That 70 kA SCCR gives you headroom for high-fault panels where a standard 25 kA or 36 kA breaker would cascade upstream. Rated In = 63 A, with a TM120M thermal-magnetic trip unit set for starter protection (motor branch circuit). The adjustable short-circuit pickup Ii = 5...15 × In lets you coordinate with downstream contactors and overloads without nuisance tripping on inrush. This variant ships without overload protection — it is a magnetic-only short-circuit protector for use ahead of a separate overload relay. The undervoltage release (UVR) coil is 24 V DC; if that control voltage drops, the breaker opens instantly, which is standard for emergency-stop chains or undervoltage protection schemes on conveyor lines. ## Deployment context The clamp terminals accept copper or aluminium conductors up to the frame's rated cross-section — no lug kit required for the main power connections. The UVR coil draws a few milliamps at 24 V DC; verify your control transformer can supply the holding current without a separate power supply.","metaTitle":"Siemens 3VA1163-6MH36-0BA0 Circuit Breaker, 70kA @ 415V, 63A","metaDescription":"Siemens 3VA1163-6MH36-0BA0 circuit breaker, 3VA1 IEC frame 160, breaking capacity class H, Icu=70kA @ 415V, 3-pole, 63A, undervoltage release 24V DC.
