Notice for New Applications
Before selecting the GX200 for new applications, we suggest you first consider GIGAVAC’s 150 Amp GX11, 225 Amp GX12, or 350Amp GX14 that accept standard size wire lugs with convenient chassis level power terminations. The EV200 was originally designed for only 200 Amps with appropriate sized terminals and pads. Over time, the EV200 current rating was increased with the assumption the user would use multiple wire lugs or use bus bars to carry the higher current. For more information about the EV200/GX200 current ratings, see the discussion under compare products.

|
In order to allow you a comparison to the Tyco/Kilovac* EV200, these GX200 ratings assume an ambient temp of 85°C, 400KCmil power cables, and a maximum terminal temperature of 150°C, which is higher than 125° allowed by UL and higher than the insulation temperature rating of some wire. This means above about 400A continuous using 150° as the maximum terminal temperature, the user must provide cables or bus bars that will pull heat from the terminals, or the ambient temperature must be reduced, or both. For UL compliant ratings, see “UL Compliant DC & AC... Ratings” below. For more information about contact ratings, see the Product Comparison.
Estimated DC Resistive Load Make & Break Life Cycle Ratings
Notes:
- Estimates are based on extrapolated data. Because every application is different, user should verify performance in the actual application.
- For the 1,800 Volt and 900 Volt ratings, the dielectric rating of the GX200 and EV200 contactors is less than the industry accepted standard of two times the source voltage, plus 1,000 volts. For details, see discussion under “Understanding Contactor Contact Ratings” on Compare Products page.
- End of life is when the insulation resistance between terminals falls below 50 megohms @500Vdc.
- The maximum make current is 650Adc, at which time welding may occur.

Electrical life rating is based on resistive load with 27µH maximum inductance in circuit. Because your application may be different, we suggest you test the contactor in your circuit to verify life is as required.
End of life is defined as when the dielectric, insulation resistance or contact resistance exceeds the specifications listed. |
1/ Assumes UL508 ratings with 400 KCmil cables, UL508 max ambient temperature of 75°C as shown, and max. UL508 terminal temperature rise of 50°C.
At 85°C ambient, contactor can also meet all of its 75°C specifications but the terminal temperature can rise can be up to 60°C, which is higher than the 50°C rise allowed by UL508 and can be higher than some cable insulation ratings.
2/ Assumes UL508 ratings with 400 KCmil cables, at a lower 50°C UL508 ambient temperature, and max. UL508 terminal temperature rise of 50°C.

1/ Assumes UL508 ratings with 400 KCmil cables, ambient max. UL508 temperature of 75°C, and max. UL508 terminal temperature rise of 50°C. Contactor can also carry the higher currents shown on page 2 at 50°C ambient, and meet all of the UL508 requirements.
Contactor meets all of its published specifications at 85°C ambient, but terminal temperature can rise 60°C, which is higher than the 50°C allowed by UL508.
The maximum terminal temperature rating is 175°C, which means much higher currents than shown on page 2 can be carried and switched. However, this temperature is much higher than most cable insulation ratings, which mean busbars must be used. Contact GIGAVAC for assistance for higher current applications.
2/ Rating consists of combined inrush + cranking current at the times specified, with 2 seconds off between cycles. This is higher current than is required for UL1107 for marine battery switches. |

Ratings are at 25ºC. For specific values at other temperatures, please contact GIGAVAC.
1/ Because the contactor is operated by a coil that changes resistance with temperature, the maximum coil voltage will be lower than indicated at temperatures above 25C, and higher than indicated at temperatures below 25C.
2/ Contactor has two coils. Both are used for pull-in, and then in approximately 75 milliseconds, one coil is electronically removed from the coil drive circuit. The remaining coil supplies low continuous hold power sufficient for the contactor to meet all of its specified performance specifications. This provides the lowest coil power possible without the use of PWM electronics that have been known to cause EMI emissions and/or cross-talk on your system control power.
3/ Because the contactor is operated by a coil that changes resistance with temperature, and because Nominal Coil voltage has been assumed for the In-Rush, Hold Current and Hold Power specifications, Current/Wattage will be lower than indicated at temperatures above 25C and higher than indicated at temperatures below 25C.
4/ For Pick-up testing of contactors with dual coils, the voltage can not be ramped up slowly, but must be applied instantly to at least the maximum pull-in voltage or current. Otherwise, the contactor will not pick-up.
5/ Because the contactor is operated by a coil that changes resistance with temperature, Pick-up Voltage, Hold Voltage, and Drop Out Voltage will be lower than indicated at temperatures below 25C and higher than indicated at temperatures above 25C.
6/ These DC coils have built-in coil suppression. The use of additional external coil suppression can slow the release time and invalidate the life cycle ratings, or can cause the contactor not to be able to interrupt the maximum current specified. If lower coil back EMF is required, please contact GIGAVAC for assistance.

To Lift and Remove the Terminal Safety Cover:
A. Push the tab of the cover to unlock it.
B. Lift the cover as shown. It will pivot on the rear pin.
C. If needed, remove the cover by pulling it straight back as shown.
D. To place the cover back in its original position, replace the cover as shown. Follow step C in reverse.
E. The cover can now pivot down to close.
F. Make sure to push the locking tab into place.
Application Information:
1. WARNING - When using more than one lug on a power terminal, make sure the primary power is closest to the contactor busbar, with the lower current lug on top, then the washer, then the lock washer, then the nut. Improper order can cause severe over-heating resulting in the possible melting of the connecting cable insulation.

5. To learn more about contactor contact ratings, see discussion under “Understanding Contactor Contact Ratings” on Compare Products page.
6. For the more user friendly panel level terminations, you may want to check out the GIGAVAC EPIC® sealed 125 Amp GX11, the 225 Amp GX12, or the 350 Amp GX14. The GX14 is nearly identical to the GX200 but has longer UL rated life and less maximum interrupt capability than the GX200. For a panel level terminal contactor with all of the GX200 ratings, contact GIGAVAC.
* Kilovac is a registered Trade Mark of Tyco International. GIGAVAC does not sell the Kilovac branded EV200 contactor, but offers the GIGAVAC GX200 as a direct alternative that we feel is better because of the EPIC® seal and other design enhancements. Compare the products. |
