That auxiliary complement means you can wire a remote status indication and a shunt-trip pushbutton without adding external relay logic — saves a DIN-rail slot and a few terminal blocks. Dimensions are 110 mm deep, 138 mm wide, and 248 mm tall. The 110 mm depth leaves room for rear-connected bus bars or a panel-mounting plate. Maximum power loss is 63.5 W — worth factoring into the enclosure thermal calculation if you're grouping several of these in a sealed cabinet.","metaTitle":"SENTRON 3VA2440-5MN32-0HH0 MCCB, 400 A, 3-Pole, Motor Protec","metaDescription":"SENTRON 3VA2440-5MN32-0HH0 molded case circuit breaker, 400 A rated at 40-70 °C, 3-pole, motor protection design, 187 kA at 240 V interrupting capacity.
