This Siemens SENTRON molded-case circuit breaker, part number 3VA5107-1MH32-0AA0, is designed for starter protection applications and is HACR Type compliant.
It features a 3-pole configuration with a rated insulation voltage of 800V and an operating voltage of 690V AC. The operational current is rated at 7A across a temperature range from 40°C to 70°C. The breaker offers significant short-circuit protection capabilities, with a maximum breaking capacity (Icu) of 150 kA at 240V and 70 kA at 415V.
Mechanically, the unit has a typical service life of 20,000 switching cycles. Its dimensions are 140mm in height, 76.2mm in width, and 76.5mm in depth. The mounting type is DIN Rail, and it utilizes a nut keeper kit for main current circuit connections.
Key electrical specifications include a maximum power loss of 3W and an active power loss of 1W per pole under hot operating conditions. The electrical endurance varies with voltage and current conditions, with 8,000 cycles at AC-1 for 380/415V and 4,000 cycles at AC-1 for 690V.
