The Siemens 3VA5215-1MU32-0AA0 is a molded-case circuit breaker from the 3VA5 series, designed for starter protection applications. This 3-pole breaker operates at a rated voltage of 690V and has an operational current rating of 150A across a wide temperature range from 40°C to 70°C.
It features a maximum breaking capacity of 200 kA at 240V, 110 kA at 415V, and 10 kA at 690V according to IEC 60947 standards. The mechanical service life is rated at a typical 20,000 switching cycles, with electrical endurance varying based on voltage and current conditions.
This circuit breaker is designed for DIN rail mounting and utilizes a nut keeper kit for front connections. Its dimensions are 185 mm in height, 105 mm in width, and 83 mm in depth. The overcurrent release is of type TM120M, providing short-circuit protection with an adjustable range of 3 to 6 times the rated current (In).
General technical data includes a rated insulation voltage of 800V and a maximum power loss of 19.6W. The active power loss per pole at rated current in a hot operating state is 6.53W. This model does not include communication functions, phase failure detection, or other measurement functions.
