The unit includes phase failure detection, which prevents single-phasing damage on a three-phase motor.
Clearance requirements are 20 mm upward, 20 mm downward, 9 mm to the side, and zero forward or backward. That means it fits into a typical motor control center bucket or sub-panel without needing extra gland-plate space; the zero forward clearance is notable for tight enclosures where the breaker sits flush against the backplane.
The 100 kA breaking capacity at 400 V (and also at 240 V, 500 V, 690 V) means this breaker can be used in high-fault-current installations — common in industrial distribution where the transformer is close to the panel. The Class 10 trip curve is the default for most IEC motor starters; if you are replacing a competitor's Class 10 breaker, this is a direct thermal match.
