Panel fit and footprint
The 3VA1132-5EF32-0AH0 measures 76.2 mm wide by 130 mm tall by 70 mm deep — a standard 3-pole MCCB footprint for DIN-rail or panel-mount integration. The 70 mm depth leaves clearance behind the gland plate for outgoing cable bends.
Breaking capacity across voltage levels
Breaking capacity is the headline rating here: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. For a 32 A frame, these numbers mean it handles high-fault-current scenarios at lower voltages typical of North American 240/277 V distribution, while still clearing substantial faults at European 400 V-class systems. The 17 kA floor at 690 V matters for industrial drives and UPS bypass circuits where line-to-line voltage is higher.
Continuous current derating
Rated 32 A from 40 °C through 50 °C ambient, then derates to 31 A at 55–60 °C and 30 A at 65–70 °C. That 2 A drop at the top end is tight — if your panel interior runs hot near the breaker, you lose about 6% of the continuous rating. The TM240 thermal-magnetic release is fixed-trip, so the derating curve is the only adjustment available in the field.
Auxiliary switch complement
Built with 2 auxiliary switches plus 1 trip alarm switch (HQ type). That gives three separate signal paths — two for status feedback (open/closed) and one dedicated to trip indication. The trip alarm output is useful for remote fault annunciation without tying up a PLC input with the main status contact.
Lifecycle and sourcing posture
Listed as current production. This is a standard catalog item in the SENTRON 3VA family, specified into new panel designs and MRO spares alike. Sourced and quoted to order against an RFQ through independent distribution — availability and current pricing confirmed at quote time.
