The breaker is fitted with a TM240 thermal-magnetic trip unit: the thermal overload protection (Ir) is adjustable from 44 A to 63 A, and the magnetic short-circuit pickup (Ii) is adjustable from 5 to 10 times In (315 A to 630 A). This adjustability lets the panel builder coordinate selectivity with upstream devices without changing the breaker itself. The 160 A frame means the breaker body and bus connections are physically sized for conductors up to that ampacity, even though the trip unit is set to 63 A; this gives headroom if you later need to uprate the trip coil. The TM240 trip is a fixed thermal-magnetic design — no electronic adjustment, no communication module — so it is a straight replacement for older Sentron or 3VL breakers in the same footprint. The clamp (box lug) terminals accept aluminum or copper conductors without compression lugs.","metaTitle":"Siemens 3VA1163-3EF36-0AF0 Circuit Breaker, 63A, 25kA @ 415V","metaDescription":"Siemens 3VA1163-3EF36-0AF0 IEC frame 160 MCCB, 3-pole, 63A, 25kA breaking capacity @ 415V.
