It uses a thermal-magnetic trip unit for overload and short-circuit protection, with a magnetic trip threshold of 149 A. That rating holds up to 690 V AC with lower values — 15 kA at 440 V, 10 kA at 500 V, 3 kA at 690 V.
Dimensions are 101 mm height, 45 mm width, 78.5 mm depth — slots into a standard enclosure without surprises. Spring terminals accept 1 to 6 mm² solid or 1.5 to 4 mm² flexible wire. Two conductors per terminal allowed, which saves space when looping through.
Compliant with EN/IEC 60947-2, EN/IEC 60947-4-1, UL 60947-4-1, and CSA C22.2 No 60947-4-1. Also tested for glow-wire at 960 °C per IEC 60695-2-11. IP20 protected, IK04 impact resistance.
