UPS Maintenance Bypass Panel Keeps Equipment Powered During UPS Maintenance
This wall-mount three-breaker maintenance bypass panel is compatible with Tripp Lite’s SVX120KL and S3M120KX 3-phase 120kVA UPS systems. It allows you to reroute power around the UPS, providing an alternate path for electricity that keeps the connected load operational while the UPS is offline for maintenance or repairs.
Features 3 Built-In Circuit Breakers to Isolate Loads
Three circuit breakers – an AC input breaker, a maintenance bypass breaker and a maintenance isolation breaker – are connected to heavy-duty buswork and isolate the UPS system from its connected load with no loss of network availability. A Kirk-key interlock system enhances safety and security. The 225-amp unit has a kAIC rating of 35.
Switching Between Normal and Bypass Modes Is Easy
When a UPS needs maintenance, this UPS bypass panel keeps power supplied to components via its mechanical interlock system by switching power to the external bypass breaker. Simply unscrew the interlock switch, rotate the switch from the UPS AC input breaker (SW1) to the bypass breaker (SW2), then turn on the bypass breaker and turn off the UPS and isolation breaker (SW3) to perform UPS maintenance without service interruption.
