MCCB for line protection — 100 A, 3-pole, TM240 release
This MCCB delivers 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. For a 415 V panel with a prospective short-circuit current of 100 kA, this breaker clears it without cascading upstream.
Above that it derates linearly: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. If your enclosure ambient runs at 55 °C, plan for 96 A continuous — not 100 A. The 15 000 latching endurance cycles give a service life estimate for switching applications.
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a compact footprint for a 100 A MCCB. The IP40 front protection means it is sealed against tools and solid objects larger than 1 mm on the front face, but not against dust ingress or water; mount it inside a panel with a higher overall rating. The reference code Q per DIN EN 81346-2 is used for circuit-breaker identification in schematics. For DC network applications, consult the 3VA device manual referenced in the datasheet.
