Raychem Frostex GFI GFI

* UL (Underwriter Lab) Inc listed Ground Fault Equipment Protection
* Separate Test and Reset buttons
* Will handle up to 15 Amps
* Internal relay cuts out both Hot and Neutral connections if fault detected. Standard American IEC pins(two flat, one round)
* All IC, diodes, transistor, capacitor and resistors etc on one pcb.
* Simple Philips screw termination: easy to install AC cord(not supplied)
* A Must for household appliance protection (e.g., if wired to replace the AC plug on a hair dryer, this GFI will cut off AC source if the dryer accidentally drops into water ) or, if water or moisture seeps into the transformer that is exposed to the elements(such as a sprinkler transformer), the AC power will cut out.

Great for AC cord manufacturers whose customers need GFI protection. If water or moisture might get into your AC equipment or appliance, this is the cheapest and easiest way to protect it .

Original price $25 each

Now: $2.50 each, sold in 100-pc carton only.

Each carton weighs about 20 lbs and costs $25 to ship GFI

within United States. Total is therefore $250 + $25= $275

Many cartons available. Same day shipment when paid with Paypal.
