It carries a rated current of 16 A up to 55 °C, derating to 15 A at 60 °C and above — so in a warm cabinet you lose 1 A of headroom above 55 °C ambient. Breaking capacity is the headline here: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The overcurrent release is a TM240 thermal-magnetic type, and the breaker is fitted with three auxiliary switches HQ.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a 3-pole MCCB footprint that fits standard Siemens SENTRON mounting plates and DIN-rail adapters.
