Mersen plug fuses are intended for industrial and residential applications.
Non time-delay fuses are available for receptacle and lighting circuits and
time-delay fuses for motor loads. For Canadian requirements, a type "P" fuse is
used for non-motor loads and Type "D" for electrical heating and cyclical load
circuits. Both fuses have low melting-point temperature elements. Type "S" plug
fuses are time-delay and tamper resistant.
