MCCB for 63 A feeder or motor branch
The Siemens 3VM1163-4ED42-0AA0 is a 4-pole molded case circuit breaker on the 3VM1 IEC frame 160 platform, rated 63 A with a 36 kA interrupting capacity at 415 V (breaking capacity class S). That 36 kA at 415 V means it handles high-fault scenarios on a 400 V three-phase distribution board without needing an upstream current-limiting fuse — it clears a bolted fault up to 36 kA and stays intact. The TM210 thermal-magnetic trip unit gives fixed overload protection at Ir=63 A and fixed short-circuit pickup at Ii=10 x In (630 A), so it's a straight line-protection breaker, not a motor-protection adjustable type. The N conductor is unprotected (no overload sensing on the neutral), which is standard for a 4-pole breaker where the neutral is switched but not monitored.
Active production, made-to-order lead
Lifecycle status is active, so this is a current-production catalog number — no end-of-life notice, no last-time-buy clock running. The product class is C: manufactured/produced to order, not a stocked shelf item. That means the factory builds it per order release, so lead time is batch-dependent rather than same-day. For a BOM freeze or a line-down replacement, get the RFQ in early enough to land in the next production window.
Panel integration and compliance
Package dimensions are 150 x 119 x 116 mm — fits a standard 4-pole MCCB footprint on a DIN rail or panel-mount base. RoHS compliant since June 2012; REACH Article 33 declares lead CAS 7439-92-1 above 0.1% w/w, which is typical for the silver-alloy contacts in the trip mechanism. No UL or CSA listing appears in the evidence, so for a North American panel that requires UL 489, verify the local listing variant or order the UL-marked suffix.
