The line-protection version covers cable and busbar faults, not motor overload curves. Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — those numbers tell you the maximum fault current it can safely interrupt at each voltage level, so the panel designer sizes the upstream transformer and bus bracing accordingly.
Thermal derating and real-world mounting
At 55 °C it derates to 60.48 A, at 60 °C to 59.22 A, at 65 °C to 57.96 A, and at 70 °C to 56.7 A. The front face is IP40, so it keeps out tools and fingers but not fine dust; mount it inside a sealed enclosure if the atmosphere is gritty. Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard 3-pole MCCB footprint that fits most DIN-rail or screw-mount panel layouts without re-drilling.
Auxiliary contacts and release options
It ships with two auxiliary switches HQ — those are the signal contacts that tell a PLC or indicator light whether the breaker is open or closed. The overcurrent release is the TM240, a fixed thermal-magnetic unit with a maximum adjustable response time of 1 second — not a solid-state electronic trip.
