Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V, and still holds 17 kA at 690 V — so it handles high-fault panels without cascading upstream. The 40 A rating holds steady from 40 °C up to 50 °C; above that it derates gradually to 36 A at 70 °C. ## Motor protection and trip unit This is the motor protection version, not a plain line breaker. ## Auxiliary and alarm contacts That's enough for remote status indication, fault annunciation, and a separate alarm for electrical trips. The integrated auxiliary trip module is order code 3VA9688-0BL30. ## Physical footprint No DIN-rail mount; it's bolted directly to the mounting plate or busbar system. ## Environmental and power loss Maximum power loss is 75 W — accounts for the internal heater and trip coil dissipation at full rated current. That matters for enclosure thermal rise calculations in a sealed panel.","metaTitle":"Siemens 3VA2140-5MN32-0HL0 SENTRON MCCB, 40 A, 3-Pole, Motor","metaDescription":"Siemens SENTRON 3VA2140-5MN32-0HL0 molded case circuit breaker, 40 A rated, 3-pole, motor protection with ETU350M electronic trip unit.
