What this MCCB is and where it goes
The 3VA1132-6EF32-0CC0: Rated 32 A continuously at 40 °C ambient (derates slightly to 30 A at 70 °C), it carries a 220 kA interrupting capacity at 240 V — that's serious fault-clearing muscle for high-available-fault installations like utility tie points or large transformer secondaries. At 415 V it still breaks 154 kA, and at 690 V it holds 17 kA. Includes an undervoltage release and two HQ auxiliary switches. Rated insulation voltage is 800 V.
Physical fit and mounting
Dimensions: 130 mm tall, 76.2 mm wide, 70 mm deep. Width of 76.2 mm (3 in) matches the typical SENTRON 3-pole slot pitch.
