It carries a continuous current rating of 63 A at 40 °C, with minimal derating up to 70 °C — at 65 °C it still holds 60 A, and at 70 °C it's rated 58 A, so you can run it warm without swapping frames. The interrupting capacity is what makes this a fast mover for plant spares: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V. That covers most low-voltage fault scenarios in a 400 V class panel without needing a current-limiting upstream breaker. Physical footprint is 130 mm tall, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB form factor that drops into existing SENTRON or comparable panel mountings without re-drilling the gland plate.
Sourcing and lifecycle — still a current-production line item
No separate undervoltage release is fitted — that's a field-add option if your safety circuit requires it.
At 70 mm deep and 76.2 mm wide, this breaker fits a standard 3-pole MCCB slot in a SENTRON distribution board or any DIN-rail-compatible enclosure. The 130 mm height leaves room for cable bending below the line terminals. Maximum power dissipation is 17.3 W — factor that into your enclosure thermal budget, especially if you're grouping several breakers in a sealed cabinet.
