1. Application
Safe and reliable electric energy allocation, continuity and control for industrial , construction and machinery manufacturing. Innovative protection concepts, and communication functions with fault diagnosis.
Features
· Compact structure, standard type(L type) and higher type( M type)
· Electric ratings: AC 400V ,50Hz/60Hz
· Up to 800A current rating
· Mounting mode: Vertical and horizontal
· Compliant standard: IEC/EN60947-2.
· High interruption, short arc (partial zero arc) and anti-vibration.
2. Selection
For example, if you order CQM3-125, standard type, three-pole, distribution, rated current 50A with 2 shunt tripper and front panel wiring , that is, to order CQM3-125L/3310 50A, qty:2.

Note：
1: According to the IEC60947-1 term "life" denotes the probability of the number of operating cycles that an electrical appliance completes before repairing or replacing components.
2: Zero flying arc cover with height of 4mm (CQM3-63L/M,), 6.2mm CQM3-100L/M, 7.5mm (CQM3-250L/M), 9.3mm (CQM3-400L/M, CQM3-630L/M) and 9.5mm (CQM3-800L/M) is selected to realize zero flying arc.
