What this MCCB is and where it fits
The Siemens 3VA1132-6ED32-0AA0 is a SENTRON 3-pole molded case circuit breaker (MCCB) carrying a 32 A continuous rating at 40 °C through 50 °C, derating to 30 A at 70 °C. It's built for line protection — meaning it sits on the incoming feeder side of a panel, not downstream on a motor branch — and uses a TM210 thermal-magnetic release that gives you fixed thermal pickup with magnetic trip factory-set at 10× In. That's a standard distribution breaker: no adjustable trip curves, no ground-fault module, no communication module. If the BOM calls for a simple, high-interrupting MCCB for a main or subfeed, this is the one.
Breaking capacity — what the numbers mean on a real line
This breaker's interrupting rating is voltage-dependent, and the spread matters. At 240 V it clears 220 kA — that's a very high fault-current capacity for a 32 A frame, typical for a main breaker close to a large transformer. At 415 V it's still 154 kA, and at 440 V it holds 121 kA. The drop to 17 kA at 500 V and 690 V tells you the arc extinction is optimized for the 240–440 V range. If your panel's available fault current is in the 100–200 kA range at 480 V or below, this part handles it without cascading an upstream breaker. Above 500 V, you need to check the 17 kA limit against your transformer's nameplate impedance.
Physical fit and panel integration
Footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — a standard 3-pole MCCB width that drops into most SENTRON or 3VA-series panelboard mounting plates without adapter brackets. The IP40 front rating means it's protected against tools and wires larger than 1 mm entering the front face, but it's not sealed against washdown; keep it inside a rated enclosure if the environment is wet or dusty. Power loss at full load is 10.6 W — negligible for thermal budgeting inside a ventilated panel, but worth noting if you're packing breakers tight in a sealed stainless enclosure.
