Over-current protection relays | Choosing the Right Protection Relay
To protect an electric motor Opt for a thermal relay, specially designed to cut off the motor's power supply when it draws too much current over a long period. To protect an electrical line Opt for an overcurrent relay, which offers sufficient protection for simple, low-cost equipment. To protect against electric shock through indirect contact Choose a differential relay, which limits earth leakage currents and protects the electrical...
