At 690 V AC the Icu drops to 42 kA, still high enough for most 690 V plant distribution. The Ics (service breaking capacity) matches the Icu at each voltage level, so the breaker clears its maximum fault and remains usable afterward without immediate replacement. ## Pollution degree 4 — this breaker lives in the dirt Pollution degree 4 per IEC 60664-1 means the ENW24243 is rated for conductive pollution environments — think cement plants, foundries, paper mills, or outdoor substations where dust or moisture creates a continuous conductive path. The 12 kV impulse withstand voltage (Uimp) and 1000 V insulation voltage (Ui) back that up: creepage distances are sized to hold off transient overvoltages even when the enclosure is grimy. IP40 on the breaker body keeps out tools and wires larger than 1 mm, but the real protection against conductive contamination comes from the internal insulation coordination, not the housing seal. Fixed-mount base plate installation, rear-connected. The 537 mm width and 352 mm height fit a standard switchgear cubicle; depth is 297 mm including the operating mechanism. Neutral on the right side of the 4-pole assembly. Connection pitch is 115 mm without a spreader — verify busbar drilling matches before torquing down.","metaTitle":"ENW24243 EasyPact NW Circuit Breaker, 3200 A, 50 kA Icu","metaDescription":"ENW24243 EasyPact NW 4P circuit breaker, 3200 A at 40 °C, 50 kA Icu at 440 V AC, IEC 60947-2.
