High Power 5V 30A SPST (1 Form A) Through Hole Relay for Heavy Duty Switching and Control Circuits
The SLA 5V 30A 1 Form A high power relay is built for efficient control of high-current loads in electronic and electrical systems requiring low-voltage actuation. With a 5V DC coil, this relay is ideal for microcontroller-driven applications such as Arduino, Raspberry Pi, and embedded systems, while still delivering a powerful 30A switching capacity. It is well-suited for controlling heavy loads including heaters, motors, inverters, and high-power lighting systems. The SPST (Single Pole Single Throw) normally open configuration provides simple and reliable ON/OFF switching for dedicated load circuits.
Designed with a robust structure and a larger footprint of 27.6x32mm, this through-hole relay ensures excellent mechanical stability and heat handling for high-current operations. It provides strong electrical isolation between the control side and load side, making it safe for use in automation systems, power supplies, and industrial control boards. The SLA series is known for its durability, consistent switching performance, and long service life in demanding environments.
