Breaking capacity reaches 242 kA at 240 V, stepping down to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. That gives you headroom for high-fault installations without oversizing the frame. The UVR ensures the breaker trips on loss of control voltage — standard for emergency-stop chains or safety isolation where you need the load guaranteed off when the control supply drops. Communication function is built in, so it can report status to a higher-level system without an add-on module. A trip indicator is present for visual confirmation at the panel face. Maximum power loss is 4.1 W, which keeps internal enclosure temperature rise manageable even in a densely packed cabinet.","metaTitle":"Siemens 3VA2140-6JQ32-0DH0 SENTRON MCCB, 40 A, 3-Pole, 242 k","metaDescription":"Siemens SENTRON 3VA2140-6JQ32-0DH0 molded case circuit breaker, 40 A rated, 3-pole, breaking capacity 242 kA at 240 V.
