Maintenance Bypass Panel APC SBP10KRMI4U Operating Temp -20 to 50°C

The APC SBP10KRMI4U maintenance bypass panel is a 19‑inch rack‑mountable unit designed to provide reliable power transfer during UPS maintenance. It supports single‑phase and three‑phase hard‑wire input configurations and offers IEC 320 C13 and C19 output connections for integration with standard server and network equipment. The unit operates in ambient temperatures from -20 to 50°C with relative humidity tolerance up to 95%, and its compact 4U form factor helps maintain continuity of power without requiring permanent changes to existing rack cabling.

Advantages

The panel delivers high power density in a 4U rack space and supports both 3‑wire (1PH+N+G) and 4‑wire (3PH+N) hard‑wire input connections, enabling flexible installation in different electrical environments. Standard IEC 320 C13 and C19 outputs make it compatible with most IT loads. Its wide operating temperature and humidity range allow installation in typical data centre and server room conditions. The unit is lightweight for its class (approximately 20.91 kg), simplifying handling during installation.

Suitable for

• Data centres and server rooms requiring uninterrupted power during UPS service
• IT racks that use IEC 320 C13 and C19 connections
• Environments needing a rack‑mountable maintenance bypass solution

How to use

Install the SBP10KRMI4U into a standard 19‑inch rack occupying 4U of space and connect the panel to the facility power using the appropriate hard‑wire input configuration for your site (3‑wire single‑phase or 4‑wire three‑phase). Route critical loads to the IEC 320 C13/C19 output sockets. When performing UPS maintenance, engage the maintenance bypass according to your site procedures to transfer the loads onto the bypass panel and isolate the UPS for service. Follow all local electrical codes and use qualified personnel for wiring and installation.

Usage recommendations

Ensure proper labeling of bypass circuits and verify load capacity before switching. Use a qualified electrician for installation and perform periodic inspections to confirm connections and mounting stability.
