This Siemens 3VA5102-1MH31-0AA0 is a molded-case circuit breaker designed for starter protection applications. It features a 3-pole configuration and a permanent rated current of 2A, maintaining this rating across operating temperatures from 40°C to 70°C.
The circuit breaker operates at a maximum rated operational voltage of 690V AC and has an insulation voltage of 800V. It provides robust short-circuit protection with a maximum breaking capacity (Icu) of 150kA at 240V and 70kA at 415V. The operating short-circuit breaking capacity (Ics) is also 150kA at 240V and 70kA at 415V. The adjustable response current (Ii) ranges from 10A to 24A.
With a mechanical service life of typically 15,000 switching cycles and electrical endurance ratings of up to 8,000 cycles at 380/415V, this breaker is built for durability. It has a compact mechanical design with dimensions of 140mm height, 76.2mm width, and 76.5mm depth. The mounting type is DIN Rail, and it features a lever actuator.
Environmental specifications include an operating ambient temperature range of -25°C to 70°C and a protection class of IP40 on the front. The breaker is compliant with various approval agencies including UL489 and is HACR Type certified.
