This Siemens 3VA5210-1BB36-0AA0 is a 3-pole molded-case circuit breaker from the 3VA5 series, designed for line protection. It features an operational current of 100A across a temperature range of 40°C to 70°C and a rated insulation voltage of 800V.
The circuit breaker has a maximum operating voltage of 690V AC and a significant short-circuit breaking capacity of 100kA at 480V, according to IEC 60947 standards. The overcurrent release is designated as MCS110, providing protection function 'I' with an adjustable response value current (li) ranging from 2500A to 2500A.
Mechanically, the unit has a typical service life of 20,000 switching cycles. Electrically, it offers endurance ratings such as 8,000 cycles at AC-1 for 380/415V and 480V, and 4,000 cycles at 690V and 600V. The device is designed for DIN rail mounting and features front connections with circular conductor terminals suitable for stranded conductors from 6 AWG to 350 kcmil.
It is compliant with UL 489 standards for HACR Type applications. The breaker does not have communication or other measurement functions, nor does it support neutral conductor retrofitting. Its dimensions are 185mm in height, 105mm in width, and 83mm in depth, with a net weight of 2.25 kg.
