Things To Consider

Cross-Reference Alternatives

Carling Technologies model numbers generally cross individual reference to the equivalent Hubbell Wiring Device-Kellems & Power First MPNs (manufacturer's part numbers). So, if you're looking for switches, circuit breakers & accessories that are either out of stock or obsolete, chances are Raptor Supplies has the alternate product available.


These Carling Technologies switches, breakers & accessories are generally small in size and require compact packaging. They are suitable for courier shipment and not air freight.
