It is Class 10 trip, detects phase failure, and has no ground-fault detection.
Short-circuit ratings and selectivity
That kind of SCCR headroom means you can usually coordinate it downstream of a larger molded-case or air circuit breaker without worrying about the motor starter becoming the weak link in a fault.
Width is 45 mm, depth 97 mm, height 97 mm.
Terminals and wiring
Main circuit connections are screw-type terminals sized for M3 screws. Accepts up to 2x 4 mm² solid or stranded, or 2x (0.75 to 2.5 mm²) — plenty for the motor leads on a fractional-to-small integral-horsepower motor. No special torque specs in the evidence, but standard M3 screw torque around 0.5–0.6 Nm will get you a reliable connection. The screw terminals are a plus for panel builders who prefer them over spring-clamp for high-vibration environments.
