DC Voltage
............. Maximum allowed voltage across the arc
suppressor (NOT operating voltage)
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
each side of the single arc suppressor or stacked arc suppressors.
Accepts a 1in #6 screw for two (2) stacked NOsparc units or a 1
¾
in
#6 screw for three (3) stacked NOsparc units.
Above is an example of two (2) MGXDC1F250 products on
DIN rail clips.
Below is just one example of many DIN Mounting Clips that are
available from a variety of suppliers.
(The example below of an appropriate
plastic DIN Rail Mounting Clip is
available from Digikey with the part
number: 277-2296-ND).
Some NOsparc distributors also carry a 3-product mounting
kit containing two (2) DIN clips and two (2) screws. Contact
your distributor for details.
