Rated insulation voltage Ui is 690 V, and the maximum operational voltage on DC circuits is 500 V. The TM210 release has a fixed I²t characteristic; the lg (long-time pickup) is adjustable down to 50 A minimum. That adjustment range covers the full 50 A rating — no derating needed at the top end. Above that, the thermal curve drops: 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, 45 A at 70 °C. Mounting footprint is 101.6 mm wide (4 in), 130 mm tall (5.1 in), 70 mm deep (2.8 in). The back and sides are open-frame, so clearance to grounded metal in the enclosure matters. ## What the TM210 release means for coordination The TM210 is a thermal-magnetic release: the thermal element (bimetal) handles overload protection with an inverse-time curve; the magnetic element (solenoid) provides instantaneous short-circuit protection. It is not electronic — no adjustable short-time pickup or I²t-on-demand. That makes it a straightforward choice for feeder protection where selectivity with downstream MCBs is achieved by time grading (the MCCB's magnetic trip is slower than a miniature breaker's instantaneous). For systems requiring zone-selective interlocking or ground-fault alarm, this is not the right variant — the 3VM series offers electronic releases in other order codes. The SENTRON 3VM series carries IEC 60947-2 certification for MCCBs. The front-face protection class is IP40.","metaTitle":"Siemens SENTRON 3VM1050-3ED42-0AA0 MCCB, 50 A, 4-Pole, 76 kA","metaDescription":"Siemens SENTRON 3VM1050-3ED42-0AA0 molded case circuit breaker, 50 A, 4-pole, 76 kA at 240 V.
