provided
Functions & Features
Surge protection type: Surge energy limiting type two-port
• Designed to protect equipment from induced
lightning surges entering through power supply cables
• High discharge current capacity type with a
maximum of 20 kA is available.
SPD
Connection
Line: M4 screw terminal (torque: 1.2 N·m)
Alarm output: Tension clamp
• 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 alert the
failure status.
Applicable wire size: 0.33 to 1.5 mm
(6 to 7 mm exposed)
Screw terminal: Nickel-plated steel

Housing material: Steel plate t = 1.2 (black)
Alarm output: SPDT relay contact trips when the thermal
breaker operates.
• Conforms to IEC 61643-1 Class II, III

*1. Sections enclosed with broken line are applicable for “alarm output” option.
The schematic shows the relay contact status of a thermal trip or power off.
*2. Be sure to make a cross-wire. If the protected device has no earth terminal, earth only the MMAJ.
*3. “PE” stands for “Protective Earth”. Besides “PE” M-RESTER has a terminal called “G”,
both terminals are for grounding.
Specifications are subject to change without notice.
