No electronic trip unit here, so no auxiliary power needed for the trip logic. ## Integrated undervoltage release and auxiliary contacts That's a common requirement for safety circuits or emergency-stop chains where loss of control power must open the main disconnect. ## Mounting and environment Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — fits standard SENTRON 3VA panel cutouts and busbar systems. Front face carries IP40 protection, so it's splash-resistant from the front but not sealed for washdown. The latching endurance is rated at 15,000 operations, which is typical for a distribution MCCB — not a switching-duty device, but fine for infrequent manual operation and fault clearing.","metaTitle":"Siemens 3VA1132-4EF36-0BH0 SENTRON MCCB, 32 A, 121 kA at 240","metaDescription":"Siemens 3VA1132-4EF36-0BH0 SENTRON molded case circuit breaker, 32 A rated current, 121 kA interrupting at 240 V, line protection, active production.
