MCCB for line protection with high interrupting capacity
The interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V, dropping to 17 kA at 500 V and 690 V — so for 400 V class systems this breaker has substantial headroom above typical available fault current.
Built-in undervoltage release; no communication or ground-fault monitoring
There is no ground-fault monitoring module and no communication function; it is a standalone thermal-magnetic MCCB.
Dimensions and environmental range
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a compact 3-pole footprint for DIN-rail or panel-mount enclosures.
At 55 °C and 60 °C it derates to 24 A; at 65 °C and 70 °C it derates to 23 A. No trip indicator is fitted.
