FEATURES
■
Varistors own two-way symmetries and can absorb positive and
negative surges
■
Able to withstand high current and high energy handling capability
■
Wide operating voltage range
■
Ideal for use as countermeasure for inductive lightning surges of
equipment which is connected to DC and AC lines
■
Absorption of surge voltages from inductive load of motors, relays etc.
and protection of semiconductor elements from excessive voltage
■
Flame retardant epoxy resin overcoating (UL94 V-0)
■
Products (82V or over) of this series are recognized

NVD14C100 is applied.
Use the varistor within the specified values as there is a risk of destruction of the varistor when the impulse power over the maximum energy is applied.
