Electromagnetic relays are commonly used in control systems, automation, power distribution, and telecommunications. They provide an efficient means of controlling circuits and switching electrical loads. EM relays are capable of handling both low and high power loads, making them suitable for a wide range of applications.
Electromagnetic relays play an inportant role in earth leakage circuit breakers
When selecting an electromagnetic relay, consider important parameters such as coil voltage, contact rating, and contact configuration. The coil voltage should match the operating voltage of the control system, while the contact rating determines the maximum current and voltage the relay can handle. The contact configuration, such as normally open (NO) or normally closed (NC), depends on the specific circuit requirements.
