Product Structure Features
The basic unit consists of a base, insulators, dynamic and static contacts, arc starting knives, arc starting contacts, arc extinguishing chambers, and other components
Adopting a manually operated spring energy storage mechanism, it has the characteristics of compact structure, small volume, comprehensive functions, light weight, fast opening and closing speed, easy operation, and high reliability
The electrical life under rated active load current is greater than 100 times, the arc ignition time is short, and the arc extinguishing performance is stable and reliable
It has three workstations: load cutting, isolation, and grounding. When cutting the load current, it can extinguish the arc. When isolating, it can form a visible fracture. When grounding, it can withstand short-circuit current.
