The 500 V rated insulation voltage (Ui) and IP40 front protection suit it for panel-mount installation in a dry, enclosed environment. The 40 A rating holds flat from 40 °C through 50 °C, then derates only 1 A per 5 °C step to 37 A at 70 °C (–) — minimal thermal compression, so you don't oversize the frame for a warm cabinet. The TM210 release's instantaneous pickup is adjustable up to 400 A, letting you tune short-circuit protection to the connected load's inrush without nuisance tripping. Dimensions are 70 mm deep, 50.8 mm wide, and 130 mm high — a compact 2-pole footprint that mounts on a DIN rail or directly to a backplate. No auxiliary contact slots are populated from the factory; if you need status feedback, plan for an external auxiliary switch block. ## DC capability and environmental range Maximum rated operational voltage on DC is 250 V — usable for DC distribution in control panels or battery-backed circuits.","metaTitle":"Siemens SENTRON 3VM1140-4ED22-0AA0 MCCB, 40A 2-Pole, 121kA a","metaDescription":"Siemens SENTRON 3VM1140-4ED22-0AA0 molded case circuit breaker. 40A, 2-pole, TM210 release. 121kA at 240V AC, 76kA at 415V AC.
