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)

■

Manufacturing range of NVD10UBC is varistor voltages 22…270. *

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.
