Mersen GSL20 Ferraz UL/CSA Listed Power Fuse 20A

Mersen Plug Fuses are for industrial and residential applications. Standard non-time delay fuses are for receptacle and lighting circuits. Standard time delay fuses are for motor loads. For Canadian requirements, a type "P" fuse is used for non-motor loads and type "D" fuses are used for electric heating and cycling loads circuits. Both fuses have low melting-point temperature elements. Low-Temp time delay plug fuses have thermal sensitivity are also for cycling loads and motor circuits. GSL20 type "S" plug fuses are time delay and tamper-resistant. Type S adaptors screw into the Edison base and allow Type S fuses to be installed. Type S adaptors prevent the wrong ampere size fuse from being used. Ferraz Shawmut GSL20 is comparable to Eaton Cooper Bussmann SL-20, 12978 920.
