Description
DESCRIPTION CIRCUIT BREAKER NG125N 4P 80A CURVE-C 18658 SCHNEIDER.
Circuit Breaker NG125N 4P 80A Schneider Curve C 18658.
The range of Schneider Electric NG125N 4-pole circuit breakers, with a breaking capacity of 25 kA, suitable for IGA group headers, normally installed in the tertiary or industrial field.
The NG125N allows the coupling of auxiliary elements and Vigi NG125 differential blocks, having to be purchased separately.
We have to take into account that each pole occupies 27 mm of width, especially when calculating the space in the electrical panel. They are mounted on DIN rail and tightened by means of hex keys.
It allows a maximum cable cross-section of 35 mm2 in flexible and up to 50 mm2 in rigid, with a stripped cable depth in terminals of 20 mm.
The tightening torque recommended by the manufacturer is 6 N.m.
C-curve tripping with a maximum operating voltage of 500 V, manually operated.
The dimensions and weight of the automatic are as follows:
– Height: 103 mm.
– Width: 108 mm.
– Depth: 81 mm.
– Weight: 0.96 kg.
Miniature MCB Acti 9, NG125N, 4P, 80A, C-curve, Thermal-magnetic, Rated current (In) 80 A at 40 °C, 0.96 kg. Breaking capacity: 50 kA Icu according to EN/IEC 60947-2, 220…240 V AC 50/60 Hz, 10 kA Icu according to EN/IEC 60947-2, 500 V AC 50/60 Hz, 25 kA Icu according to EN/IEC 60947-2, 380…415 V AC 50/60 Hz, 20 kA Icu according to EN/IEC 60947-2, 440 V AC 50/60 Hz, 20 kA Icu according to EN/IEC 60947-2, <= 500 V DC. Benefits: With the advantages of all the ease of a modular installation, the NG125 circuit breaker combines the performance and robustness required in the most demanding industrial installations. Applications: Protection in all industrial and tertiary buildings: Entrance protection in modular enclosures. Projections in power distribution panels.
