Breaking capacity is specified per the standard at multiple voltages: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V.
Integrated auxiliary and shunt trip
The trip alarm signals the breaker's open state after a fault, which is useful for remote annunciation in a PLC-based monitoring scheme.
Panel fit and thermal management
The MCCB occupies a 101.6 mm width (4 in) and 70 mm depth (2.76 in) on the DIN rail or mounting plate. Maximum power loss is 17.3 W at rated load, which should be factored into enclosure thermal calculations — particularly in a sealed panel with multiple breakers ganged together.
