APC by Schneider Electric SBP20KP 20kVA Rack-Mount Service Bypass Panel
Overview
The APC by Schneider Electric SBP20KP is a 20,000 VA service bypass panel designed for data centers and critical facilities that need to take a UPS offline for maintenance without dropping the load. At 4U rack height and rated for up to 125A, this unit lets technicians safely isolate, service, or replace an upstream UPS while connected equipment stays live — the single most important feature in any always-on environment. Browse the full APC by Schneider Electric catalog for the complete power protection lineup.
This panel fits into the broader category of power distribution and bypass equipment alongside APC's UPS families, and pairs directly with high-capacity three-phase and single-phase UPS systems operating at 200–240V. If you're spec'ing a redundant power architecture, review our UPS and power protection buying guide for topology and sizing guidance before finalizing your bypass strategy.
Key Features
- 20,000 VA / 125A Maximum Current: Handles full-load bypass for large UPS installations up to 20kVA — enough headroom for mid-to-large server rooms, broadcast facilities, or industrial control environments running high-draw equipment around the clock.
- Wide Input Voltage Range (200–240V, plus 380/400/415V): Supports both standard North American 208V three-phase legs and international 380–415V infrastructure. One SKU covers multi-region deployments without sourcing a country-specific variant.
- 99% Bypass Efficiency: When utility power routes through the bypass path, losses are negligible — critical when the bypass state is sustained during extended maintenance windows rather than just momentary transfers.
- Circuit Breaker Protection: Integrated circuit breaker on the bypass path provides overcurrent protection without requiring external fusible disconnects, simplifying the installation and reducing the number of single points of failure in the power chain.
- 4U Rack-Mount Form Factor (43.2 × 55.4 cm footprint): Fits standard 19-inch equipment racks. At 19.32 kg, it requires two-person installation or a rack lift — plan accordingly. Pairs with APC rack enclosures for a fully integrated power bay.
- -20°C to 50°C Operating Range: Rated for environments from cold storage anteroom to warm server closet. The 0–95% relative humidity tolerance means it can be deployed in facilities without precision air conditioning, as long as condensation is controlled.
- Operating Altitude to 15,000 ft: Suitable for high-altitude data centers and facilities — a spec that matters in mountain-region installations where standard equipment derates earlier.
- CSA and GOST Certified: CSA marks the unit for Canadian installations; GOST covers Russian Federation approval. Verify local AHJ requirements before specifying for other regions.
Integration and Compatibility
The SBP20KP is engineered to work within APC's Symmetra and Galaxy UPS families at the 20kVA class. Confirm your UPS model's bypass panel compatibility in APC's compatibility tool or contact pre-sales engineering with your UPS model number before ordering. Input voltage flexibility (200/208/220/230/240V on the load side; 380/400/415V on the input side for three-phase feeds) means this unit integrates into both North American and international electrical infrastructure without rewiring the distribution panel — a real advantage in mixed-region enterprise rollouts.
Frequently Asked Questions
Q: What UPS systems is the SBP20KP designed to work with?
A: The SBP20KP is a 20kVA-class service bypass panel designed for use with APC UPS systems at compatible capacity ratings. Confirm specific UPS model compatibility using APC's online selector or consult pre-sales engineering with your UPS model number before ordering.
Q: What is the maximum current rating of the SBP20KP?
A: The SBP20KP is rated for 125A maximum line current on both input and output sides.
Q: Does the SBP20KP support three-phase input?
A: The input voltage range includes 380V, 400V, and 415V — voltages consistent with three-phase distribution. Confirm your specific wiring configuration with an electrician familiar with the installation environment.
Q: What rack space does the SBP20KP require?
A: The SBP20KP occupies 4U in a standard 19-inch rack. Its depth is 55.4 cm (approximately 21.8 inches) — verify clearance in your rack before ordering.
Q: What certifications does the SBP20KP carry?
A: The SBP20KP is certified to CSA (Canadian Standards Association) and GOST standards. Verify with your local authority having jurisdiction for region-specific compliance requirements.
Q: What is the warranty on the SBP20KP?
A: APC provides a 2-year parts-only manufacturer warranty on the SBP20KP.
The SBP20KP is the unit I spec when a facility can't tolerate a maintenance blackout on a 20kVA UPS — the bypass path runs at 99% efficiency, so even extended maintenance windows on utility power don't translate into meaningful heat or energy loss at 125A full load.
Technical Highlights:
- 125A / 20,000 VA Capacity: Sized for large UPS installations. At full 125A draw, the integrated circuit breaker provides overcurrent protection without external fusible hardware — one less failure point in the distribution chain.
- Voltage Flexibility (200–415V Input): Covers single-phase 208–240V North American feeds and three-phase 380–415V international infrastructure in a single SKU — eliminates country-specific procurement for multi-region enterprise deployments.
- -20°C to 50°C Operating Range at 0–15,000 ft Altitude: Operational envelope extends to high-altitude facilities and uncontrolled environments — useful for edge data centers in mountain regions where standard equipment derates or requires derating calculations.
Deployment Considerations:
- At 19.32 kg and 55.4 cm depth, this is a two-person rack installation — confirm both vertical clearance (4U) and depth clearance before the unit ships, especially in older or shallower rack enclosures.
- CSA and GOST are the only listed certifications; if your project requires UL listing or CE marking, verify with APC's compliance team before specifying — do not assume regional certification coverage beyond what the evidence states.
This panel earns its place in large enterprise data centers and broadcast infrastructure where UPS service intervals are planned events, not emergencies — specifically any 20kVA installation where taking the load offline, even briefly, is operationally unacceptable.
