The differences lie in their application scope, structure, and operating principle.
1. Application Scope: Capacitor contactors are primarily used for capacitor switching control to achieve reactive power compensation; regular contactors are widely used in various electrical control systems to control the switching of loads such as motors and lighting fixtures.
2. Structure and Operating Principle: Capacitor contactors add capacitor switching control functionality to the basic functions of regular contactors, and have special arc-extinguishing devices and capacitor protection functions; regular contactors mainly consist of an electromagnetic mechanism, contact system, and arc-extinguishing device, used to control the opening and closing of circuits.
