The 690 V AC insulation voltage (Ui) and 8 kV impulse withstand (Uimp) place it squarely in industrial distribution, not residential final circuits. Tunnel terminals accept 1.5…50 mm² rigid copper; strip 20 mm and torque to 3.5 N·m. At 108 mm wide for four poles, it fills about six modular spaces on the rail — plan your gland-plate fill accordingly. ## Electrical durability and frequency range Rated for 10,000 electrical cycles — adequate for a distribution feeder or motor branch circuit that sees a few operations per day. Network frequency covers 50…60 Hz, so it works on both 50 Hz European and 60 Hz North American grids without derating.","metaTitle":"Schneider NG125L Circuit Breaker, 32 A 4-Pole, 690 V","metaDescription":"Schneider NG125L 4-pole circuit breaker, 32 A at 40 °C, 690 V insulation, 8 kV impulse.
