Lightning Surge Protectors for

Electronics Equipment M-RESTER

LIGHTNING SURGE PROTECTOR FOR

POWER SUPPLY USE

(200 V / 220 V / 240 V AC, single phase)

Functions & Features

• Designed for installation where AC power enters the

control panel for relatively large power consuming

equipment such as large instrumentation panels, computer

systems or telemetering systems in central control rooms or

operation centers

• Composed of air-core reactors, large capacity discharge

elements and electromagnetic contactors

• Thermal fuse in parallel with the discharge element opens

and cuts off the operating circuit for the electromagnetic

contactor in case of discharge elements failure, thus

protecting the equipment connected to the arrester
