Engineering Specifications & Design Criteria

Our contactors are manufactured in Liushi Town under certified ISO9001 procedures. Designed strictly around IEC 60947-4-1 guidelines, each contactor undergoes strict coil pull-in testing, insulation resistance validation, and temperature-rise evaluations before shipping.

Silver Nickel Contact Tips

Equipped with wear-resistant Ag-CdO / Ag-SnO2 silver tips that prevent contact welding during severe inductive inrush current peaks.

High Duty Copper Coil

Precision-wound vacuum varnished copper coils guarantee stable pull-in at 85%-110% Us and clean drop-out at 20%-75% Us without hum.

Arc Chute Technology

Multi-plate arc splitters quickly extinguish switching arcs, substantially extending electrical lifespan in heavy AC-3 and AC-4 cycles.
