Breaking capacity is the headline here: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 42 kA at 690 V. That SCCR headroom means this 4-pole breaker can be specified into panels fed from large transformers or high-capacity gensets without worrying about cascading failure upstream. The IP40 front protection means it's suitable for enclosed switchboards where the door provides the environmental seal. At 1.6 W maximum power loss, heat dissipation inside the enclosure is manageable even in densely packed MCC sections. ## Protection and configuration The ETU340 release is a microprocessor-based trip unit with LSI protection curves (long-time, short-time, instantaneous) plus ground-fault capability — though this specific variant ships without ground-fault monitoring. Communication function is not fitted, so this is a standalone breaker for hardwired protection schemes.","metaTitle":"Siemens 3VA2140-6HK46-0AA0 SENTRON MCCB, 40A, 4-Pole, 242kA","metaDescription":"Siemens 3VA2140-6HK46-0AA0 SENTRON molded case circuit breaker, 40 A rated current, 4 poles, 242 kA breaking capacity at 240 V, ETU340 release.
