Potential hazards related to relay protection

Home / Potential hazards related to relay protection

Refer to the Safety Precautions for individual Relays for precautions specific to each Relay. Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. Hazardous environment relays must withstand explosive atmospheres, chemical vapors, and combustible dusts without creating ignition sources.
