LIGHTNING SURGE PROTECTOR  
GENERAL SPECIFICATIONS  
Construction: Wall-mounted, front terminals; terminal cover  
FOR POWER SUPPLY USE  
(fast response: 3 nsec.)  
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
