The TM240 thermal-magnetic trip unit gives an overload protection range (Ir) adjustable from 44 A to 63 A, so you set it to match the full-load amps of the protected conductor or load, not the breaker's fixed In. Short-circuit pickup (Ii) is adjustable 5 to 10 times In (315 A to 630 A), letting you coordinate downstream with smaller branch breakers or motor starters. ## Deployment context The clamp connection terminals accept copper or aluminum conductors up to the rated cross-section for the frame size — no lug kit needed for most panel builds. The integrated shunt trip (STL) coil, rated 220-250 V DC or 208-277 V AC, allows remote tripping from an E-stop circuit or fire-alarm relay, which is common in machine-tool and HVAC distribution panels.","metaTitle":"Siemens 3VA1163-4EF36-0KC0 Circuit Breaker, 63A, 36kA @ 415V","metaDescription":"Siemens 3VA1163-4EF36-0KC0 IEC frame 160 circuit breaker, 3-pole, 63A, breaking capacity 36kA @ 415V.
