Painless Fan-Thom Electric Fan Relay (PW30101)

This is inexpensive protection for an electric fan and a vehicle's wire harness. Provides constant voltage, protects from voltage and amperage spikes and prevents the fan from back feeding voltage through the vehicle's wire harness. An absolute necessity if adding a dash mounted manual on/off switch to your electric fan circuit.

Kit Includes:

• SPST 40 Amp relay
• 30 Amp circuit breaker
• Relay base with harness
