Lightning Surge Protectors for
Electronics Equipment M-RESTER
ONE-PORT SURGE PROTECTOR
BETWEEN NEUTRAL AND PROTECTIVE EARTH
Functions & Features
• Designed to protect electronics equipment from induced
lightning surges with gas discharge tube
• One-port surge protector according to IEC61643-1
• Connected between neutral and protective earth
• High discharge current capacity of 40 kA (8/20 μs)
• Protect against overvoltage between N and PE caused by
earth fault
• No interruption of power supply even when the head
element is removed: easy maintenance and replacing
• Degraded head element is automatically separated from
the power lines to prevent overheating, with a relay contact
output to alert the failure status.
• Head-base connection is keyed so that only a head
element of correct line voltage can be mounted.
Typical Applications
• Protection between N and PE of TT system
• Low-voltage distribution board
• Combination with installation for large load current

GENERAL SPECIFICATIONS
Construction: Plug-in
Degree of protection: IP20 (If the solderless terminals are
covered with insulation tubes.)
Surge protection type: Voltage switching type one-port SPD
(IEC61643-1)
Discharge element: Gas discharge tube
Connection
Line: M5 screw terminal (spring up-screw type)
(torque: 2.5 N·m)
Alarm output: Euro type connector terminal
(torque: 0.25 N·m)
Applicable wire size
Line connection: See the sloderless terminal drawing.
Alarm output: 0.14 to 1.5 mm
2
(7 mm exposed)
Housing material: Flame-resistant resin (black)
Alarm output: The SPDT relay trips when the thermal
breaker operates and/or the head element is removed.
Rated load: 250 V AC @0.5 A (resistive load)
125 V AC @0.2 A (resistive load)
Minimum switching load: 5 V DC, 1 mA
Line voltage identification key: The connection of the head
element and the base is keyed for exact matching.
Safety function: Thermal breaker incorporated
Failure indicator: The check window color changes from
green (normal) to black (failed and the thermal breaker
separated the M-rester from the circuit).
