That flat thermal performance simplifies panel design when the breaker shares an enclosure with heat-generating gear like drives or transformers. ## Integrated accessories and wiring The shunt trip lets a remote safety relay or PLC drop the breaker under fault or E-stop conditions without a manual action. The trip alarm switch signals the open state back to the control system — useful for a remote annunciator or a safety circuit that needs to confirm the breaker is open before allowing a restart. Power loss is 5.4 W maximum, low enough that ventilation slots in a standard enclosure handle the heat without forced air. The breaker includes a voltage trigger and a trip indicator — the indicator gives a local visual confirmation of a trip event, which speeds fault isolation on a multi-breaker panel.","metaTitle":"Siemens 3VA2063-5HN32-0KG0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA2063-5HN32-0KG0 SENTRON molded case circuit breaker, 63 A continuous, 3-pole, 187 kA interrupting at 240 V.
