Functions & Features
• High discharge current capacity 10 kA (8 / 20 μs)
• Ultra-thin 7-mm-wide module can be mounted
in high density
Connection: Euro terminal block (torque 0.3 N·m)
Applicable wire size: 0.2 – 2.5 mm2, stripped length 8 mm
Grounding: DIN Rail
• Excellent protection employing multi-stage SPD circuits
• DIN rail mounting and grounding
• Power line monitor LED
Housing material: Flame-resistant resin (black)
Monitor LED: Green LED turns ON when the voltage is
supplied; OFF when the safety fuse is blown.
Typical Applications
• Protecting small capacity AC control drives
• Protecting small capacity power supply units
INSTALLATION
AC power supply: Max. output current 3 A
Caution: Use an AC power source with the overload current
protection function.

Operating temperature: -25 to +85°C (-13 to +185°F)
Operating humidity: 30 to 90 %RH (non-condensing)
Mounting: DIN Rail (TH35-7.5, 1-mm-thick)
Oxide film on the surface of an aluminium DIN rail may
lower the electric conductivity between this module and the
ground. Use a steel or copper rail.

Grounding
Grounding
*1. Oxide film on the surface of an aluminium rail may lower the electric conductivity between this module and the ground.
Use a steel or copper rail.
*2. Be sure to ground the DIN rail. Recommended grounding resistance ≤100Ω
*3. Cross-wire between the DIN rail and the metal housing of the protected device to equalize the earth potential.
Ground only the surge protector when the protected device has no ground terminal.
*4. Use an AC power source with the overload current protection function. (maximum output current 3A)
*5. Install a current limiting element (capacity 3) when the output current exceeds 3A.
Specifications are subject to change without notice.
