Rated 100 A continuous at 40 °C, it carries that same rating through 50 °C, then derates to 91 A at 70 °C — useful to know if the breaker sits in a warm enclosure. Breaking capacity is 121 kA at 240 V, dropping to 75.6 kA at 415 V and 52.5 kA at 440 V — still high enough for most secondary distribution applications. At 690 V it holds 11.9 kA.
The breaker measures 130 mm high by 101.6 mm wide by 70 mm deep, fitting standard panel-mount cutouts for 4-pole SENTRON MCCBs. It ships with four auxiliary switches (HQ type) pre-installed — verify the auxiliary contact wiring scheme matches your control circuit before panel wiring. Maximum power loss is 25 W; account for that heat in enclosure sizing, especially when grouping multiple breakers.
