This Siemens 3VA5 series molded-case circuit breaker, part number 3VA5110-4EC41-0AA0, is designed for system protection applications. It features a 4-pole configuration and a permanent rated current (Iu) of 100A, with operational current ratings varying slightly with ambient temperature from 100A at 40°C down to 88.1A at 70°C.
The breaker operates at a maximum rated operational voltage of 690V AC and 600V DC, with an insulation voltage of 800V. It offers significant breaking capacities, including 55kA at 240V and 36kA at 415V according to IEC standards, and 25kA at 480V according to UL 489 standards. The short-circuit protection is adjustable, with a minimum li of 500A and a maximum of 1000A.
With a mechanical service life of typically 15,000 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 type. The unit is compliant with various approval agencies including CCC, CE, CSA, EAC, UL489, and VDE.
