1. Authorization prior to returning product is required.

Please refer to your original purchase agreement or

contact your distributor or sales representative for an

RMA number and instructions before returning product.

2. After we receive your return, we will examine it and try to

verify the reason for returning it.

3. In cases of manufacturing defect, we will enter a

replacement order or issue credit for product returned. In

cases of customer misuse, we will request a purchase

order to provide replacement product.

4. To return products that are not defective, goods must be

in new condition, in the original boxes and they must be

returned within 120 days of receipt. A 20 percent

restocking charge is applied for all returned stock.

5. Arc Suppression Technologies reserves the right to

charge for no trouble found (NTF) returns.

CASE SPECIFICATIONS AND MOUNTING

CASE DIMENSIONS

DIN RAIL MOUNTING

DIN rail mounting of one (1), two (2), or three (3) stacked arc

suppressors can be accomplished by

adding a single DIN rail mounting

adaptor (NOT PROVIDED) (accepting

up to a 1¾ inch #6 screw) to each side

of the single arc suppressor or stacked

arc suppressors.

Note: The above images are a representation only. DIN

Mounting Clips are available from a variety of suppliers.

(One example of an appropriate plastic DIN Rail Mounting

Clip is available from Digikey with the part number: 277-

2296-ND).

PRODUCT DESCRIPTION

The NOsparc MGXDC1F250 (DC power applications) is a

two-terminal contact arc suppressor that attaches across the

contact points of a power relay, contactor, or snap action

switch. The product is designed to protect the contact

points from premature destruction due to contact current

arcing. This extends contact life 10X or more depending on

application.

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.

DEFINITIONS

Arc Current ............. Plasma flow supported between open

contacts

Arc Suppression

Duration .................. Time during which the electrical current

contact arc is arrested

Arc Suppressor ...... Device designed to reduce contact

arcing

Break ....................... Action of a contact which transitions

from close to open

Bounce .................... One or more brief transition(s) to the

OPEN state as the contact is closing or

to the CLOSE state as the contact is

opening

Break Current ......... Contact current during Break

Cycle Time ............. Time between successive ON or OFF

contact states

Inductive Load ....... Motor or transformer form the main part

of the load

Inrush Current ........ Resulting turn-on current when

powering an inductive, capacitive or

tungsten load

Inrush Current

Limiter ..................... Device intended to limit the amount of

turn-on current when powering an

inductive, capacitive or tungsten load

Make ....................... Action of a contact which transitions

from open to close

Make Current ......... Contact current during Make

MOV ........................ Metal Oxide Varistor

MTBF ...................... Mean-Time-Between-Failures

Power-On

Passthrough ........... Current passing through the arc

suppressor during initial power-up

RC Snubber ............ Device with resistor and capacitor in

series across contact

Snubber .................. Device designed to limit voltage rise

times

Suppression ............ Action of minimization of undesired

event

Varistor Clamping

Voltage ................... Voltage at which steady state current

through the arc suppressor is ≥ 1mA

Maximum Varistor

DC Voltage ............. Maximum allowed voltage across the

arc suppressor (NOT operating voltage)
