This Siemens 3VA5107-1MU32-0AA0 is a 3-pole molded-case circuit breaker from the 3VA5 series, specifically designed for starter protection applications. It features an operational current of 7A across various temperature ratings from 40°C to 70°C and a rated insulation voltage of 800V with an operating voltage of 690V AC.
The circuit breaker provides robust protection with a maximum short-circuit breaking capacity (Icu) of 150 kA at 240V and 70 kA at 415V. Its mechanical service life is rated at a typical 20,000 switching cycles, with electrical endurance varying based on voltage and load conditions.
Designed for front connection with a nut keeper kit on both ends, it supports conductor cross-sections from 12 x 1 mm up to 17 x 6.5 mm. The unit is mounted on a DIN rail and has dimensions of 140 mm in height, 76.2 mm in width, and 76.5 mm in depth. It does not include communication functions or phase failure detection.
This breaker is UL 489 listed for HACR Type applications. It operates without ground-fault monitoring and features a TM120M overcurrent release.
