Lightning Surge Protectors for

Electronics Equipment M-RESTER

LIGHTNING SURGE PROTECTOR

FOR THREE-PHASE POWER SUPPLY

Functions & Features

• Connected in parallel between the power and earth lines

regardless of load current

• Applicable to single phase 2/3-wire and threephase 3/4-

wire system

• High discharge current capacity 20 kA or 40 kA (8/20 μs)

• Degraded head element is automatically separated from

the power lines by the incorporated thermal breaker, and

the LED lamp (turns off) and the relay contact alerts the

failure status.

• Complies with IEC 61643-11 Class II

Typical Applications

• Low-voltage distribution board

• Combination with installation for large load current
