This 3-pole unit carries the TM120M thermal-magnetic trip — the thermal element provides starter protection (motor overload curve), while the magnetic short-circuit pickup is adjustable from 5 to 15 times In (315 A to 945 A). The 'AM' designation means it ships without overload protection on the magnetic side, so the thermal curve governs running overloads and the magnetic element handles only short-circuit events. That split makes it suited for motor branch circuits where a separate overload relay handles the running protection. The clamp-type terminals accept copper or aluminum conductors without lugs, which speeds panel wiring. The UVR coil terminals are separate from the main power lugs; verify the control circuit voltage matches the 208-230 V AC coil rating before energizing. The clamp connectors accept conductor cross-sections typical for 63 A branch circuits — no special lug kit needed.","metaTitle":"3VA1163-5MH36-0DA0 Circuit Breaker 3VA1, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5MH36-0DA0 IEC frame 160 MCCB, 63A, 55kA breaking capacity @ 415V, starter protection TM120M, UVR 208-230V AC.
