PRODUCT DESCRIPTION

The MGXDC1F250 contact arc suppressor (DC power applications)

protects, cleans, and restores the contact points of relays and

contactors. This improves their overall performance and extends

contact life to the mechanical life of the relay or contactor.

The MGXDC1F250 arc suppressor is designed to suppress

contact arcing from 12Vdc to 250Vdc. It connects across the

contact terminals on existing products and equipment using

only two wires.

In simple terms, NOsparc operates as follows:

1. NOsparc detects the occurrence of an arc event.

2. NOsparc activates to suppress the arc.

3. NOsparc deactivates when the contacts are open and

suppression is not required.

4. NOsparc is continuously protected by over-voltage suppression.

PRODUCT DIMENSIONS AND MOUNTING

NOsparc MGXDC1F250 dimensions:

PANEL MOUNTING

Panel mounting of an arc suppressor can be accomplished

using a #6 screw through the two mounting holes.

DIN RAIL MOUNTING

Optional DIN rail mounting (shown left) of up to three (3) stacked

MGXDC1F250 products can be accomplished by adding a single

DIN rail mounting adaptor (NOT PROVIDED), with a #6 screw to

the

arc

each side of the single arc suppressor or stacked arc suppressors.

Accepts a 1in #6 screw for two (2) stacked NOsparc units or a 1¾in

#6 screw for three (3) stacked NOsparc units.
