If your panel sits near a furnace or drive cabinet that pushes internal air past 50 °C, size the load side accordingly — the breaker will trip earlier than a cold-bench test suggests. Dimensions: 130 mm height, 76.2 mm width (3-pole base), 70 mm depth. The shunt trip release (order code 3VA9688-0BL33) is integrated; no external wiring needed for the trip coil.","metaTitle":"Siemens 3VA1132-5EF32-0KH0 SENTRON MCCB, 32A, 187kA at 240V","metaDescription":"Siemens 3VA1132-5EF32-0KH0 SENTRON molded case circuit breaker, 32 A rated continuous current, 187 kA interrupting at 240 V, TM240 release, shunt trip.
