Lightning Surge Protectors for

Electronics Equipment M-RESTER

ONE-PORT SURGE PROTECTOR FOR

POWER SUPPLY USE

(class I)

Functions & Features

• Designed to protect electronics equipment from direct

lightning surges entering through power supply cables.

• Connected in parallel between the power and ground lines

regardless of load current

• High discharge current capacity of 25 kA (10/350 μsec.)

• Detect degraded discharge element, with a relay contact

output to alert the failure status.

Typical Applications

• Installation in service entrance switch gear
