More about air breaker accessories and parts

Air breakers are complex electromechanical devices with multiple serviceable accessories and parts. Trip units — whether thermal-magnetic, solid state, or electronic — are the most commonly replaced accessory when upgrading protection capabilities. Operators include closing spring motors, manual charging assemblies, and solenoid mechanisms that control breaker operation. Shunt trip coils enable remote tripping from external control circuits, while contacts — both main and arcing — wear over time and require periodic replacement to maintain safe current-carrying capacity. Arc chutes, auxiliary switches, undervoltage releases, and bell alarm contacts round out the essential air breaker accessories that keep these critical devices performing to specification.
