About the Allis-Chalmers SDO Oil Circuit Breaker
The Allis-Chalmers SDO is an oil circuit breaker used in substation fault interruption applications. Its interrupter assembly includes a stationary contact mount, upper arcing nozzle, offset rod, retaining ring, bottom plate, interrupter shell, and spring. The interrupter components wear through interrupting duty and require replacement at overhaul. Southern Switch machines replacement components and stocks complete interrupter kits for the Allis-Chalmers SDO.
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.
