What it is and what it does
The Siemens SENTRON 3VA1163-5ED46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 63 A at 40 °C through 50 °C before derating begins — at 70 °C it still holds 58 A. The TM210 thermal-magnetic release handles overload and short-circuit protection in one package, so there's no separate relay to wire in.
Breaking capacity — what the numbers mean for your fault level
This MCCB interrupts 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. Those are the maximum fault currents the breaker can safely clear at each voltage level — if your available fault current at the panel exceeds the rating for your system voltage, you need a current-limiting upstream device or a higher-rated frame. The 187 kA figure at 240 V is unusually high for a 63 A frame; it's sized for high-fault industrial services where the transformer is close.
Panel fit and integration
The breaker measures 101.6 mm wide, 130 mm high, and 70 mm deep — a standard SENTRON 3VA frame footprint that drops into existing DIN-rail or panel-mount layouts without re-drilling. Front IP40 protection means it's sealed against tools and wires but not washdown; keep it inside the enclosure. The 4-pole configuration covers three-phase plus neutral, common for TT or TN-S systems where the neutral needs overcurrent protection. Rated insulation voltage is 800 V, so it's comfortable on 690 V line-to-line systems with margin.
What the TM210 release and power loss tell you
The TM210 designation means a thermal-magnetic release with a fixed thermal pickup and adjustable magnetic trip — the '210' typically indicates the magnetic trip is set at 10x In (630 A), so it's a standard motor-and-distribution profile, not a selective or high-inrush variant. Maximum power loss is 17.3 W at rated current, which matters for enclosure thermal calculations if you're packing several breakers in a sealed cabinet. An optional motor drive extension is available for remote switching.
