Thermal Overload Protector - SN-2


The SN-2 delivers the maximum protection in the smallest package at an excellent price. It’s the most reliable on the market, backed by the leading innovators in protection technology. Each SN-2 has a bimetal disc specifically manufactured for each rating. Each device is then calibrated and checked for opening temperature. This results in optimum snap–acting open and reset characteristics necessary to achieve consistent performance over the required cycle life. The SN-2 protector is our most popular product, and it is 4.7 mm thick with contact rating of up to 12 Amps.
