SENTRON 3VA1150-5EE36-0AC0 — 50 A MCCB with TM220 Release
The Siemens SENTRON 3VA1150-5EE36-0AC0 is a 3-pole molded case circuit breaker (MCCB) with a TM220 thermal-magnetic release, rated 50 A at 40 °C. Interrupting capacity is 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — that covers most industrial service entrances and sub-distribution boards without needing a current-limiting fuse upstream. Thermal derating is gradual: holds 50 A up to 50 °C, then drops to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C.
Dimensions: 130 mm height, 76.2 mm width (3 in), 70 mm depth. Comes with 2 auxiliary switches (HQ design) factory-fitted.
