At 240 V this MCCB interrupts 187 kA — that's well into industrial-grade SCCR territory, meaning it can ride through a major fault without upstream coordination issues. At 415 V and 440 V it still holds 121 kA, and at 500 V it manages 75.6 kA. The 690 V figure drops to 3.7 kA, so verify your system voltage against that curve before specifying for 690 V applications. The 86 mm depth (3.39 in) means it clears most shallow enclosures without a deep gland plate. Maximum power loss is 1.6 W — negligible heat contribution inside the cabinet.","metaTitle":"Siemens 3VA2140-5MN32-0AA0 SENTRON MCCB, 40 A, 3-Pole, Motor","metaDescription":"Siemens 3VA2140-5MN32-0AA0 SENTRON molded case circuit breaker, 40 A rated at 40 °C, 3-pole, 187 kA at 240 V.
