Description

The CA Series of transient surge suppressors are industrial

high-energy disc varistors (MOVs) intended for special

applications requiring unique electrical contact or packaging

methods provided by the customer. The electrode ﬁnish

of these devices is solderable and can also be used with

pressure contacts. Discs of the same diameter may be

stacked.

This series of industrial disc varistors are nominal 60mm

diameter, with disc thickness ranging from 2.0mm

minimum to 32mm maximum. The voltage range is 250V

to 2800 V

For information on soldering considerations, refer to EC637

"Recommendations for Soldering Terminal Leads to MOV

Varistor Discs."
