Four poles, TM220 thermal-magnetic release, no undervoltage or shunt trip, no communication module. It is a straightforward main or feeder breaker for a 400 V class distribution board.
Breaking capacity — the real fault-clearing envelope
The interrupting ratings span the voltage range a panel sees: 121 kA at 240 V, 75.6 kA at 415 V and 440 V, 52.5 kA at 500 V, and 11.9 kA at 690 V. At 415 V — the common low-voltage distribution level — 75.6 kA gives generous SCCR headroom for most industrial switchboards. The 690 V figure (11.9 kA) is low enough that a high-fault 690 V bus may need a current-limiting upstream device; verify coordination.
Above 50 °C it drops: 313 A at 55 °C, 306 A at 60 °C, 299 A at 65 °C, 292 A at 70 °C. Maximum power loss is 80.1 W at rated load, which matters for enclosure thermal rise calculations.
Dimensions: 248 mm high, 184 mm wide, 110 mm deep. Four-pole frame, so it occupies the full width of a standard distribution board mounting plate. IP40 on the front — protected against solid objects over 1 mm, no water ingress protection; install inside a rated enclosure.
