Maximum power loss is 10.6 W, which keeps the internal temperature rise manageable in a crowded panel. The shunt trip (STL) and two HQ auxiliary switches are built in, so you don't need separate add-on modules for remote trip or status feedback.","metaTitle":"Siemens SENTRON 3VA1132-3EF36-0HC0 MCCB, 32 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1132-3EF36-0HC0 molded case circuit breaker, 32 A rated, 3-pole, breaking capacity 75.6 kA at 240 V.
