Breaking capacity is 25 kA at 400 V AC. For a 400 V panel fed by a 630 kVA transformer, that covers the typical secondary fault level. The 100 kA rating at 240 V AC handles high-fault locations on the low-voltage side. No screw torque to verify — termination is tool-less and vibration-resistant. Good for a panel that sees frequent transport or machine-mounted duty. Rated insulation voltage covers 20 to 690 V, so it's suitable for 400 V and 480 V systems with headroom for 690 V line-to-line applications.
Mounting position any orientation. That's the minimum free air for arc quenching — don't crowd it against a gland plate or enclosure wall. The spring-loaded terminals exit the bottom — leave the 50 mm downward clearance for cable bend radius.
