High Power 5V 30A SPDT (1 Form C) Through Hole Relay for Heavy Duty Switching and Embedded Control Applications
The SLA 5V 30A 1 Form C high power relay is designed for reliable switching of high-current loads using low-voltage control signals. With a 5V DC coil, it is ideal for microcontroller-based systems such as Arduino, Raspberry Pi, and embedded control boards, while delivering a powerful 30A contact switching capacity. This relay is suitable for controlling heavy electrical loads including motors, heaters, inverters, compressors, and high-power lighting systems. The SPDT (Single Pole Double Throw) configuration supports both normally open (NO) and normally closed (NC) contacts, offering flexible circuit control options.
Built with a rugged design and a large footprint of 27.6x32mm, this through-hole relay ensures strong PCB mounting and effective heat dissipation during high-current operation. It provides excellent electrical isolation between the control and load circuits, enhancing safety and system reliability. The SLA series relay is widely used in automation systems, power management circuits, home appliances, and industrial electronics where durability and consistent switching performance are essential.
