APC by Schneider Electric E3SBPSU10K20F Easy UPS 3S Maintenance Bypass Panel
Overview
The E3SBPSU10K20F is APC by Schneider Electric's single-unit maintenance bypass panel for the Easy UPS 3S series, covering the 10–20KVA range at 208V. Its purpose is straightforward but operationally critical: it lets you take a UPS offline for scheduled maintenance, firmware updates, or unplanned service without ever cutting power to the connected load. In data centers, server rooms, and industrial facilities, the alternative — shutting down protected equipment to service the UPS — is rarely acceptable. This panel removes that constraint.
Sized at 550mm wide × 260mm deep × 600mm tall, the E3SBPSU10K20F is designed to install alongside its companion Easy UPS 3S unit, giving maintenance technicians a clean transfer path from UPS output to raw bypass feed and back. RoHS compliance means it meets current environmental regulations on restricted substances, relevant for facilities operating under EU or equivalent standards.
Key Features
- Maintenance Bypass Function: Transfers the connected load from the UPS output to a direct mains bypass path — and back — without interrupting power to downstream equipment. This is the core reason this panel exists: zero-downtime UPS servicing in production environments.
- 10–20KVA 208V Coverage: Covers the full single-unit Easy UPS 3S range at 208V, from 10KVA through 20KVA. One panel SKU covers both ends of the range, which simplifies sparing and procurement for sites running mixed-capacity deployments.
- Operating Temperature 0–40°C: Rated for the full range of conditioned data center and server room environments. The 0°C lower bound means it also handles cold-start conditions in unheated equipment rooms during winter commissioning or power restoration after an outage.
- Operating Humidity 0–95% (Non-Condensing): A wide humidity tolerance reduces the risk of the panel becoming the weak link in facilities with imperfect environmental control — useful in edge deployments, industrial closets, or older building infrastructure.
- RoHS Compliant: Meets the EU Restriction of Hazardous Substances directive. Required for projects with EU sustainability mandates, government contracts with environmental reporting requirements, or facilities pursuing LEED or similar green-building certifications.
- Compact Enclosure — 550 × 260 × 600mm: At roughly 21.7
