Product details

Breaking capacity — what it handles

Rated breaking capacity is 100 kA at 240 V, 30 kA at 400 V, 6 kA at 500 V, and 3 kA at 690 V. At 480 V and 600 V the continuous current rating is 17 A — this is the motor FLA it carries, not the short-circuit interrupt.

Any mounting position. Terminal accepts 2x 1–25 mm² or 1x 1–35 mm² solid or stranded. Main contact terminals are M6. The 55 mm width means it occupies three standard 18 mm DIN spaces — plan the gland plate fill factor accordingly.

Current production — no end-of-life notice. This is the active catalog number for the SIRIUS motor protection breaker family at this rating.
