The Siemens 3VA5212-5GC41-0AA0 is a 4-pole molded-case circuit breaker from the 3VA5 UL frame 250 series, designed for system protection applications. This breaker has a rated operational current of 125A and a maximum breaking capacity of 35kA at 480V according to UL 489 standards. It operates with a rated operational voltage of up to 690V AC and 1000V DC.
The overcurrent release is of type TM230 with LI protection function, offering overload protection set at Ir=125A and fixed short-circuit protection from 5 to 10 times the rated current (Ii=5...10 x In). It also includes 100% N conductor protection. The breaker is suitable for HACR Type applications as per UL 489.
With a mechanical service life of typically 20,000 switching cycles and electrical endurance ratings of up to 8,000 cycles at 380/415V AC, this circuit breaker is built for durability. It is designed for DIN rail mounting and features a lever actuator. The maximum power dissipation is 22.6W.
