The Siemens 3VA5212-7EF41-0AA0 is a 4-pole molded-case circuit breaker from the 3VA5 series, designed for system protection applications. This breaker operates with a nominal current of 125A and offers a maximum rated operational voltage of 690V AC and 1000V DC.
Key electrical characteristics include a breaking capacity of 100kA at 480V (UL 489) and 85kA at 415V (IEC 60947). The overload protection is adjustable between 100A and 125A, with a short-circuit protection range of 5 to 10 times the nominal current. The breaker is built for durability, with a typical mechanical service life of 20,000 switching cycles and electrical endurance ratings of up to 8,000 cycles at 380/415V.
Designed for DIN rail mounting, this circuit breaker utilizes a lever actuator. It is rated for HACR Type applications and features a TM240 overcurrent release with LI protection function. The N-conductor is unprotected, and ground-fault monitoring is not included. The maximum power loss is rated at 22.6W.
