The TM240 thermal-magnetic overcurrent release gives it a rated current of 160 A at 40 °C, with the same rating holding through 50 °C before a slight derate curve begins at 55 °C. Breaking capacity is the headline spec here: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 500 V and 690 V. Maximum power loss is 38 W — useful to know for thermal management inside a sealed enclosure.
Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a standard 3-pole MCCB footprint that fits most Siemens SENTRON distribution panels and retrofit slots. The auxiliary switch block accommodates up to four HQ auxiliary switches, and the breaker ships without ground-fault monitoring.
