It interrupts 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — numbers that tell you the SCCR headroom for a line-side transformer or a generator-fed bus. The TM240 release means the thermal pickup is fixed; you get a single time-band adjustment (tr max. 1 s) on the magnetic trip, not a full electronic curve.
The 100 A rating holds from 40 °C through 50 °C ambient; above that it steps down — 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, 90 A at 70 °C. Width is 76.2 mm, depth 70 mm, height 130 mm — a standard 3-pole MCCB footprint that drops into a SENTRON distribution board or a separate enclosure.
What the auxiliary contact version gives you
This variant ships with 2 auxiliary switches (HQ type) built in. That means you get two form-C contacts for status feedback — one to signal the breaker's open/closed state to a PLC or indicator lamp, the other for a remote trip alarm. No separate add-on module needed.
