At 415 V it still holds 121 kA, and at 690 V it drops to 4.5 kA, so the voltage you're protecting at determines the fault-current headroom. It's designed for starter protection, meaning it's built to coordinate with motor contactors and overload relays in a motor control center (MCC) or individual starter bucket. ## Thermal derating — the real-world current you can pull Above that it starts to step down: 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, and 142 A at 70 °C (–). If this breaker lives in a sealed enclosure next to a drive or transformer, expect internal ambient to hit 55–60 °C — plan for 151–156 A continuous, not the full 160 A. The 35.5 W maximum power loss is the heat it dumps into the enclosure; factor that into your thermal budget. ## Auxiliaries and releases — what's inside the package That's typical for emergency-stop or safety circuits where loss of power must open the motor circuit. The trip indicator provides local visual confirmation of a fault trip vs. manual open. Width: 105 mm (4.13 in), height: 158 mm (6.22 in), depth: 70 mm (2.76 in) (–, –). That's a compact 3-pole MCCB footprint — fits standard 160 A frame cutouts in switchgear or MCC buckets. The 70 mm depth means it won't protrude past the gland plate in most enclosures. Mounting is via the rear panel or DIN rail adapter (check the specific 3VA1 mounting kit for your enclosure). ## Environmental range","metaTitle":"Siemens 3VA1216-5MH32-0DH0 SENTRON MCCB, 160 A, 3-Pole, 187","metaDescription":"Siemens 3VA1216-5MH32-0DH0 SENTRON molded case circuit breaker, 160 A rated current, 3-pole, 187 kA breaking capacity at 240 V.
