About the Siemens Allis-Chalmers BZO-115 Oil Circuit Breaker
The Siemens Allis-Chalmers BZO-115 is an oil circuit breaker with an interrupter design using a baffle stack assembly, arcing nozzle, G-10 push rod, moving contact, and stationary contact to interrupt fault current in oil. The interrupter components require replacement at the manufacturer's recommended overhaul interval. Southern Switch stocks complete kits and individual components for the BZO-115.
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.
