MAL

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
