The 80 A continuous rating is the load it carries in normal service; the thermal-magnetic trip handles both overload (thermal bimetal) and short-circuit (magnetic solenoid) in one unit. This breaker sits in the ComPacT NSXm family — the compact, modular frame sized for distribution boards where panel depth is tight. At 108 mm wide (12 module pitches of 9 mm), 137 mm high, 80 mm deep, it fits backplate-mounted enclosures with front-connect compression lugs or busbars. The 4-pole configuration (3 phases + switched neutral, neutral left) covers three-phase distribution with full neutral protection.
Standards, approvals, and environmental limits
IK07 resists 2 J impact — enough for a cabinet door but not a hammer swing. Operating altitude 2000 m without derating, up to 5000 m with derating. Relative humidity 0–95 %. Electrical endurance: 20,000 cycles at 440 V at In/2, 10,000 cycles at 440 V at In. Mechanical endurance: 20,000 cycles. That is the lifecycle to plan around for panel maintenance intervals — after roughly 20,000 switch operations under load, the contacts are worn and the breaker should be replaced.
