High Power 12V 30A SPST (1 Form A) Through Hole Relay for Heavy Load Switching and Industrial Applications
The SLA 12V 30A 1 Form A high power relay is designed for robust switching of high-current loads in demanding electrical and electronic systems. Operating on a 12V DC coil, this relay is suitable for automotive circuits, industrial control panels, battery-powered systems, and power distribution units. With a high contact rating of 30A, it can efficiently control heavy loads such as compressors, inverters, heating elements, and high-power lighting. The SPST (Single Pole Single Throw) normally open configuration ensures simple and reliable ON/OFF switching for dedicated load control.
Featuring a larger footprint of 27.6 x 32mm, this through-hole relay provides strong mechanical stability and secure PCB mounting. It offers excellent electrical isolation between control and load circuits, enhancing safety in high-power applications. Built for long operational life and consistent performance, the SLA series relay is widely used in automation systems, UPS units, solar power systems, and industrial electronics where durability and high current handling are critical.
