A 12V 100A relay is an essential component used in various industries and applications that require high power control. It is a crucial device for switching high-current loads while maintaining the safety and reliability of electrical circuits. This article explores the features, working principles, and common applications of the 12V 100A relay.

What is a 12V 100A Relay? A 12V 100A relay is a type of electrical relay designed to handle a 12V DC voltage for the coil (activating voltage) while providing up to 100A of switching capacity on the load side. The relay operates by using an electromagnet to open or close contacts in a circuit, allowing or preventing the flow of electricity. These relays typically have multiple contacts (normally open or normally closed) and can handle both AC and DC loads, with their load handling capacity varying depending on the design. Key Features Coil Voltage： The coil of a 12V 100A relay is designed to operate with a 12V DC power source. This makes it suitable for automotive, solar power, and other low-voltage systems where a 12V battery is commonly used.
