Overview
Contact kit for the Siemens / Allis-Chalmers SDO oil circuit breaker — stationary contact finger, nozzle, moving contact rod, finger spring, and washers.
Why replace worn OCB contacts
Pitted or eroded oil-circuit-breaker contacts increase resistance and weaken interruption. Precision replacements restore dependable making and breaking under load.
