The interrupting capacity is 121 kA at 240 VAC, stepping down to 75.6 kA at 415 VAC and 52.5 kA at 440 VAC; at 500 V and 690 V it holds 11.9 kA.
The 50 A continuous rating holds across ambient temperatures up to 50 °C without derating; at 55 °C it drops to 49 A, at 60 °C to 48 A, and at 70 °C to 45 A — relevant if the breaker sits in a warm enclosure near other heat sources. The TM240 trip unit is a fixed thermal-magnetic design — no electronic adjustment or communication function — so it is a straight swap for existing thermal-magnetic MCCB installations where selectivity and coordination are already calculated.
Dimensions are 130 mm height, 101.6 mm width, 70 mm depth — fits standard MCCB panel cutouts and DIN-rail adapters for the SENTRON 3VA platform. No undervoltage release, no shunt trip, no ground-fault monitoring module fitted on this variant; those are added via accessory slots if needed.
