MCCB for line protection with undervoltage release
It carries a 121 kA breaking capacity at 240 V and 75.6 kA at 415 V, which means it can safely interrupt high fault currents on a 400 V panelboard without needing an upstream current-limiting fuse. The TM240 thermal-magnetic trip unit gives a fixed thermal pickup of 32 A and a magnetic trip threshold of 240 A — the magnetic setting is 7.5x the rated current, so it handles motor inrush without nuisance trips on pump or compressor starts.
The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into a SENTRON panelboard or a DIN-rail adapter without re-drilling. No communication module or ground-fault monitoring is fitted on this variant; it's a straight line-protection device with the UVR as the only auxiliary release.
