Its interrupting capacity is 75.6 kA at 240 V AC and 9 kA at 415 V AC, which means it can safely clear a fault up to those levels without catastrophic failure — critical for panel coordination studies where the available fault current is known.
Above that, derating is gradual: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. No guesswork.
Physical fit and mounting
This 1-pole breaker occupies a single 25.4 mm (1 inch) module width on the DIN rail. Overall dimensions are 130 mm height, 25.4 mm width, and 70 mm depth. No undervoltage release, no shunt trip, no auxiliary contacts, and no communication function are built in. This is a bare thermal-magnetic breaker for basic line protection. If you need remote tripping or status feedback, you will need the accessory modules from the 3VA family.
For BOM-line sourcing, this part is quoted and supplied to order against an RFQ. No minimum-buy or long lead-time constraints are associated with this order code.
