This Siemens SENTRON 3VA5215-1MU36-0AA0 is a 3-pole molded-case circuit breaker, specifically designed for starter protection applications. It operates at a rated insulation voltage of 800V and an AC operating voltage of 690V.
The breaker features a 150A operational current across a temperature range of 40°C to 70°C. Its short-circuit protection is defined by Ii=3...6 x In. The breaking capacity according to IEC 60947 includes a maximum short-circuit current (Icu) of 200 kA at 240V, 110 kA at 415V, and 10 kA at 690V. The operating short-circuit current (Ics) is also 200 kA at 240V.
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 circuit breaker is built for durability. It has a net weight of 2.2 kg and dimensions of 185 mm height, 105 mm width, and 83 mm depth. The connection type is front connection with circular conductor terminals on both sides, supporting stranded conductors from 6 AWG to 350 kcmil.
This model is UL 489 listed as HACR Type and includes the TM120M overcurrent release. It is mounted on a DIN rail.
