CyberPower P403URC1 4-Outlet Surge Protector with USB Charging
Overview
The CyberPower P403URC1 is a compact, wall-mountable surge protector built around four NEMA 5-15R outlets and a resettable 15A circuit breaker — a practical choice for small equipment clusters in security head-end closets, desktop workstations, or AV equipment racks where you need surge protection and USB device charging from a single unit. The P403URC1 delivers 500 joules of surge energy absorption on a white plastic housing sized to fit tight utility spaces.
Unlike disposable strip-style surge protectors that require a complete unit swap after a breaker trip, the P403URC1 uses a resettable circuit breaker — field-serviceable without calling an electrician or pulling a replacement unit from stock. For power protection equipment in commercial environments, that distinction matters when a tripped breaker at 2 AM is the difference between a five-second fix and a service call.
Key Features
- 500-Joule Surge Energy Rating: absorbs transient voltage spikes before they reach connected equipment. At 500J, this unit is suited for general-purpose electronics and peripheral protection — not a substitute for a dedicated UPS on mission-critical network gear, but appropriate coverage for workstations, monitors, and USB-charged devices at a security desk or operator station.
- 800V Clamping Voltage: the voltage level at which the surge protector begins diverting excess energy. Lower clamping voltage means tighter protection; 800V is within standard range for equipment rated to handle typical utility-grade transients. Pair with a UPS upstream if your equipment has stricter tolerance requirements.
- 15,000A Peak Current (Normal Mode): the maximum surge current the MOV-based protection circuit can handle in a single event. At 15kA, it covers the vast majority of utility-induced transients including nearby lightning strike coupling — though a direct strike is outside any MOV's protection envelope.
- 1ms Response Time: the protection circuit engages within one millisecond of a detected surge. Fast enough for standard transient events; equipment with sub-millisecond sensitivity should be evaluated against this spec before deployment.
- Resettable 15A Circuit Breaker: press-to-reset breaker replaces the fuse-style protection found on cheaper strips. When an overload trips the breaker, reset takes seconds — no tools, no replacement parts. Rated at 15A, which matches a standard 15A NEMA 5-15P wall circuit.
- 4x NEMA 5-15R Outlets: standard North American 15A outlets in a 4-position strip. No surge-protected outlets are dedicated to always-on use — all four share the same protection path. Plan outlet count carefully if you need to serve more than four receptacles from a single strip.
- 2x USB Charging Ports: integrated USB-A ports for direct device charging without occupying an AC outlet. Useful at operator desks, visitor check-in stations, or any position where tablets, handheld scanners, or phone chargers compete for outlet space.
- 32 dB EMI/RFI Noise Filtering: attenuates electromagnetic and radio frequency interference on the AC line. In environments near variable-frequency drives, switching power supplies, or dense wireless infrastructure, even modest EMI filtering reduces noise artifacts that can affect sensitive analog inputs or audio equipment.
- 6,000V Maximum Data-Side Voltage Rating: this spec applies to any connected data line protection if data ports are present. Verify your specific connection type is covered before routing signal lines through the unit.
- NEMA 5-15P Power Plug: standard 15A North American plug connects directly to any standard 15A duplex outlet. No adapter required in typical US commercial installations.
Integration and Compatibility
The P403URC1 fits into standard surge protector applications across security, AV, and general commercial IT deployments. The NEMA 5-15P plug and 5-15R outlets are universal in North American 15A circuits. The white housing suits exposed-installation environments — reception desks, training rooms, or any space where aesthetics are a consideration alongside function. For rack-mounted equipment, a rack-format PDU with surge protection is the more appropriate fit; the P403URC1 is optimized for desk and shelf deployment.
USB charging is natively compatible with any USB-A charging device. The 2-port configuration handles simultaneous tablet and phone charging without a hub. For deployments integrating PoE-powered devices, note that this unit provides AC-side protection only — PoE-injected circuits require separate surge suppression on the data/power line.
Frequently Asked Questions
Q: How many outlets does the CyberPower P403URC1 have?
A: The P403URC1 includes four NEMA 5-15R AC outlets, all surge-protected, plus two USB-A charging ports that do not consume any AC outlet positions.
Q: What is the surge energy rating of the P403URC1?
A: The P403URC1 is rated at 500 joules of surge energy absorption. This is appropriate for desktop electronics, monitors, and peripheral devices. For mission-critical network or security recording equipment, consider pairing with a higher-joule UPS upstream.
Q: Does the P403URC1 have a resettable breaker or a fuse?
A: It uses a resettable 15A circuit breaker. If an overload trips the breaker, you press the reset button to restore power — no replacement parts or tools needed.
Q: What is the clamping voltage on the P403URC1?
A: The clamping voltage is 800V. This is the threshold at which the surge protection circuitry begins diverting excess voltage away from connected equipment.
Q: Can the P403URC1 be used in a server rack?
A: The P403URC1 is a horizontal strip form factor designed for desk and shelf use, not rack mounting. For rack deployments, a 1U rack-mount PDU with surge protection is the correct choice.
Q: Does the P403URC1 filter EMI/RFI noise?
A: Yes. The unit provides 32 dB of EMI/RFI noise filtering on the AC line, which reduces interference from nearby switching power supplies, motor drives, or dense wireless equipment.
The P403URC1 is one of those units I recommend specifically when a security integrator needs a clean, no-fuss surge strip for operator desk positions — the resettable 15A breaker is the feature that earns it a spot in commercial deployments over comparable consumer strips. At 500J energy absorption and 800V clamping, it's well-matched to the electronics load at a guard station or access control workstation, without overspecifying for an application that doesn't need a full UPS.
Technical Highlights:
- 500J Energy Rating: sufficient for desktop computers, monitors, and USB-charged devices at operator stations — not positioned as primary protection for NVR or server-class equipment, which should have a higher-joule UPS in the circuit.
- 32 dB EMI/RFI Filtering: meaningful in security head-end rooms with high-density switching power supplies, where unfiltered line noise can show up as artifacts in analog audio or cause nuisance resets on sensitive peripherals.
- Dual USB-A Ports: lets integrators leave all four NEMA 5-15R outlets for equipment while still providing device charging — a practical detail when outlet count is tight at a reception or monitoring desk.
Deployment Considerations:
- The 15A rating matches a standard 15A wall circuit — confirm you're not mixing this onto a 20A dedicated circuit where a 20A-rated PDU would be the appropriate spec.
- Watch the outlet count: four outlets fills fast once you account for a workstation, monitor, VOIP phone, and a secondary display — plan before install rather than daisy-chaining another strip downstream, which defeats the protection intent.
Best fit for security desk and operator console positions in commercial buildings — reception counters, guard booths, and access control workstations where you need clean power, USB charging, and a field-resettable breaker in a compact white form factor.
