What this MCCB carries and where it lands
The 3VA1132-5ED26-0AA0 is a 2-pole SENTRON molded case circuit breaker rated 32 A continuous at 40 °C, with a TM210 thermal-magnetic release tuned for line protection — meaning it handles overload and short-circuit in one device, no external relay needed. Interrupting capacity hits 187 kA at 240 V AC and 121 kA at 415 V AC, so it clears high-fault conditions without cascading upstream on a 415 V panel feed. Rated operating voltage is 415 V AC and 250 V DC, insulation rated 500 V — covers most commercial and light industrial distribution boards.
Panel fit and thermal derating
Footprint is 50.8 mm wide (2 in), 130 mm tall, 70 mm deep — two-pole width on a DIN-rail or panel-mount assembly, so it occupies one standard MCCB slot. Current rating holds flat at 32 A from 40 °C through 50 °C, then steps down to 31 A at 55–60 °C, and 30 A at 65–70 °C. No derating needed for most ventilated enclosures; at 70 °C ambient you lose 2 A. Front IP40 protection — fine for a dry indoor panel; not rated for washdown.
Lifecycle and sourcing posture
This is a standard catalog item from the SENTRON 3VA family, designed for line protection with no communication function, no undervoltage release, and no ground-fault monitoring — a straightforward thermal-magnetic MCCB for distribution panels.
