Siemens 3VA5150-6EC31-0AA0 65kA Circuit Breaker
Siemens 3VA5 Series 3-Pole Molded Case Circuit Breaker.
The Siemens 3VA5150-6EC31-0AA0 is a 3-pole molded case circuit breaker from the 3VA5 series, featuring a 125A frame size and a nominal current (In) of 50A. It provides a robust breaking capacity of 65 kA at 480V. This model uses TM230 protection with an FTAM trip unit, including overload protection (Ir) set at 50A and adjustable short-circuit protection (Ii) from 5 to 10 times the nominal current.
This circuit breaker is ideal for demanding industrial applications where a high interrupting rating is essential. It offers reliable protection for main feeders, large motor circuits, and distribution systems with significant fault current potential. The adjustable Ii setting allows for finer tuning of protection coordination.
