For motor circuits with higher inrush, a D-curve breaker would be the better pick. At the rated operational voltage of 380/415 V AC, the breaking capacity will be lower per the manufacturer's derating curve; check the coordination tables if you're feeding a high-fault panel. ## Panel fit and environment Snaps onto DIN rail; dimensions are 81 x 103 x 54 mm, so it takes up a standard 2-module width. Torque the terminals to 3.5 Nm — that's the spec for the screw clamps, and under-torquing is the most common cause of thermal trip nuisance in the field. Designed to IEC 60947-2, the standard for low-voltage switchgear and controlgear circuit breakers.","metaTitle":"Merlin Gerin NG125NC16A Miniature Circuit Breaker, C Curve,","metaDescription":"Merlin Gerin NG125NC16A miniature circuit breaker, C curve, 16 A, 2 pole, 50 kA breaking capacity at 240 V.
