(Note: conventional wiring method for 100\~630 type)

Fire control does not require additional intermediate relay (DC24V input)

Warning!

This secondary wiring is strictly prohibited from connecting to an active power supply

Series Surge Protective Device (SPD)

Scope of application

EBS1 series products have a large flow capacity and are suitable for C-level (Il-level) and D-levelIll-level) protection in low-voltage distribution systems.

Different combination wiring methods are chosen based on different power supply systems.

High energy varistor, nanosecond response speed;

Equipped with overheating and overcurrent protection;

(Local indicationl) and remote alarm contact2);

1)It visually displays the working status of the protector on the protector

2)It provides contacts for remote monitoring of protector status, which requires external wiring.

Pluggable in charged condition, module replaceable in case of failure.
