The Siemens 3VA5150-1MU32-0AA0 is a 3-pole molded-case circuit breaker from the SENTRON series, specifically designed for starter protection applications. It operates at a rated insulation voltage of 800V and an operating voltage of 690V AC.
This circuit breaker features an operational current of 50A across a temperature range from 40°C to 70°C. Its breaking capacity according to IEC 60947 includes a maximum short-circuit current (Icu) of 70 kA at 415V and 10 kA at 690V. The operating short-circuit current (Ics) is 70 kA at 415V and 5 kA at 690V.
With a mechanical service life of typically 20,000 switching cycles and electrical endurance ratings of up to 8,000 cycles at 380/415V, this breaker is built for durability. It has a net weight of 1.034 kg and is designed for front connection using a nut keeper kit on both ends. The dimensions are 140 mm in height, 76.2 mm in width, and 76.5 mm in depth. It is suitable for DIN rail mounting.
