This MCCB delivers 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. For a 415 V panel with a prospective fault level of, say, 85 kA, this breaker clears it with margin. At 690 V the 17 kA figure is the limit; if your upstream transformer can deliver more, step up to a higher-rated frame.
Above that it derates: 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, 112.5 A at 70 °C.
Built-in undervoltage release
When line voltage drops below the release threshold, the breaker trips. That is useful for motor circuits that must not auto-restart after a brownout, or for safety disconnects that need to drop out on loss of control voltage. No separate auxiliary contact block is fitted on this version.
Panel fit and protection class
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration.
