The TM240 thermal-magnetic release gives a fixed thermal pickup at 50 A and a magnetic trip threshold of 240 A (4.8× Iu), so it clears moderate overloads thermally and short-circuit faults magnetically without needing an external trip unit. The 50 A rating holds flat from 40 °C up to 50 °C, then derates to 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. The trip indicator is present, so you get local visual confirmation of a fault trip. ## Integration notes — panel fit and wiring The breaker occupies a 76.2 mm width (3-pole), 130 mm height, and 70 mm depth — a standard SENTRON 3VA footprint that fits existing DIN-rail or mounting-plate layouts without re-drilling. The undervoltage release coil must be wired to a separate control voltage; verify polarity and suppression per the device manual.","metaTitle":"Siemens 3VA1150-5EF36-0DH0 SENTRON MCCB, 50 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1150-5EF36-0DH0 molded case circuit breaker, 50 A rated, 3-pole, 187 kA at 240 V.
