These Relays are very reliable due to the fully automated manufacturing process and sophisticated coil winding procedure. The SPST High Current Relay is rated at 30 amps with an input voltage of 12 volts DC. The relay is ideal for use with the MSD RPM Activated Switch when 12 volts are responsible for activating a high current device such as a nitrous solenoid.The DPST relay is also rated at 30 amps with a 12 volt input voltage. This Relay is the best choice when 12 volts are required to activate multiple high current devices at the same time such as multiple stage nitrous solenoids.
