This is a line-protection variant — no ground-fault monitoring, no phase-failure detection, no communication module, and no auxiliary contacts. The only integrated auxiliary release is a shunt trip (STL) with order code 3VA9688-0BL30. If your BOM calls for under-voltage release or an alarm contact, this isn't the variant. ## Thermal derating matters above 55 °C At 55 °C it derates to 38.4 A, at 60 °C to 37.6 A, at 65 °C to 36.8 A, and at 70 °C to 36 A. Size the breaker for the actual enclosure temperature, not the nameplate. ## No trip indicator, no aux contacts — plan your panel wiring This MCCB lacks a trip indicator and has no auxiliary contact block. If the PLC needs a remote tripped signal, you'll need to add an external auxiliary switch or monitor the shunt trip circuit. Dimensions: 130 mm height, 76.2 mm width, 70 mm depth — fits standard SENTRON 3VA mounting footprint.","metaTitle":"Siemens SENTRON 3VA1140-5EF36-0HA0 MCCB, 40 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1140-5EF36-0HA0 molded case circuit breaker, 40 A rated, 3-pole, 187 kA breaking capacity at 240 V.
