This Siemens SENTRON 3VA5 series molded-case circuit breaker, part number 3VA5210-7EF31-2AA0, is designed for system protection. It features a 3-pole configuration and a current rating of 100A, with an operational current of 100A at 40°C, decreasing to 84A at 70°C.
The circuit breaker has a rated AC voltage of 690V and a rated DC voltage of 750V, with an insulation voltage of 800V. It offers a maximum short-circuit current breaking capacity (Icu) of 200 kA at 240V and 10 kA at 690V. The operating short-circuit current breaking capacity (Ics) is also specified, with values matching the Icu for the tested voltages.
Adjustable parameters include the setting current (Ir) for L-tripping, ranging from 80A to 100A, and a fixed delay time (tr) of 1 second. The short-circuit protection setting current (Ii) minimum is 500A.
With a mechanical service life of typically 20,000 operating cycles and electrical endurance up to 8,000 cycles at 380/415V, this breaker is built for durability. It has a net weight of 2,100g and dimensions of 185mm height, 83mm depth, and 105mm width. The mounting type is DIN Rail. It is approved by multiple agencies including UL, CE, and DNV.
