Siemens 3VA5215-6EC31-0AA0 Molded Case Circuit Breaker

Siemens 3VA5215-6EC31-0AA0 is a three-pole molded‑case circuit breaker in the SENTRON 3VA5 family, rated for 150 A with a 65 kA short‑circuit rating at 480 V AC. This fixed‑mount MCCB uses a TM230 overcurrent release with LI (long‑time/instantaneous) protection and FTAM line protection and is HACR‑type for loads such as heating, air conditioning, and refrigeration circuits. Rated insulation voltage Ui is 800 V and max operating voltage Ue is 750 V DC, with 50/60 Hz operation; the unit weighs 2.016 kg and is designed for fixed mounting in a 3‑pole configuration. The operating current is 150 A at 40 °C (derating to 132 A at 60 °C), while mechanical life is about 20,000 switching cycles and electrical endurance around 8,000 cycles at common distribution voltages.
