• Three-stage SPD-20mA surge protection device meets standard

protection against power surges, voltage surges and

disturbances with three stages of protection.

• Housed in a din rail panel mount case with a protected earth

ground.

• In order to work properly, it is important to have a good

connection in E terminal to solid earth ground.

• Unknown electronic device failure and misbehave in controller

units might be avoided by using SPD-20mA

Features:

• Protection provided by high energy MOV and TVS

• Replaceable modular design, DIN Rail compatible base

• All types of 20mA current loop devices, Also works for HART

interface

Where to Use:

*Noisy industrial lines like DC inductive load switching

*Industrial power panels

*Solar plants

*Gas stations
