The 70 mm depth and 76.2 mm width fit the standard SENTRON 3VA footprint — it drops into the same DIN-rail slot as the 3VA1110 frame, so a panel originally laid out for the lower-rated sibling accepts this one without re-drilling the gland plate. ## Integration and thermal management The TM240 release means the thermal element is calibrated for a 240 A frame, but the breaker itself is rated 125 A continuous; the magnetic pickup is fixed and non-adjustable. The 70 mm depth keeps the breaker within the standard 3VA envelope, so it fits existing panel layouts without increasing the back-panel clearance.","metaTitle":"SENTRON 3VA1112-4EF36-0AH0 MCCB, 125 A, 3-Pole, TM240","metaDescription":"SENTRON 3VA1112-4EF36-0AH0 molded case circuit breaker, 125 A at 40 °C, 3-pole, TM240 release.
