Description

La Series Transient Surge Suppressors Are Radial-lead Varistors That Can Be Operated Continuously

Across Ac Power Lines. These Ul Recognized Varistors "across-the-line" Components, Because Of Their

Radial Lead Construction, Require Very Little Mounting Space. This Feature Is Particularly Important

in compact, hard wired system designs.

La Series Varistors Are Available In Four Model Sizes: 7mm, 10mm, 14mm And 20mm; And Have A

Vm(ac)rms Voltage Range From 130v To 1000v, And An Energy Absorption Capability Up To 360j. Some La

Series Model Numbers Are Available With Two Clamping Voltage Selections, Designated By A Model

Number Pre X Of Either A Or B. The "a" Selection Is The Standard Model; The "b" Selection Provides

a tighter clamping voltage.
