EPIC® Hermetic Sealed DC and AC Contactor - 350+ Amp Power Switching
RoHS Compliant, all date codes

 

 

 

Contactor Features

https://lithium-car-battery.3dcartstores.com/assets/images/bullet.gif

Rugged EPIC® Ceramic-to-Metal Seal Rated to 175°C – Reduced risk of fire or meltdown in over-current conditions compared to the less-durable epoxy seal.

https://lithium-car-battery.3dcartstores.com/assets/images/bullet.gif

EPIC® Hermetic Seal – Designed to meet UL1604 for Class I & II, Div 2 and Class III for use in hazardous locations, IP67 for temporary water immersion for 30 min, SAE J1171 - external ignition protection, and ISO8846 for protection against ignition around flammable gasses.

https://lithium-car-battery.3dcartstores.com/assets/images/bullet.gif

High Efficiency Dual Coils - Unlike the PWM coil economizer found in other contactors that can cause cross-talk on your system control power or radiate noise, the Contactor uses two coils. One drops out after the contactor is energized providing low power to keep the contactor energized.

https://lithium-car-battery.3dcartstores.com/assets/images/bullet.gif

No Exposed Coil Electronics - The Contactor can operate almost anywhere, even under water - unlike other contactors with exposed PWM coil electronics that can fail in harsh environments.

https://lithium-car-battery.3dcartstores.com/assets/images/bullet.gif

Built-in Power Terminal Safety Cover - Extra assurance of a safer connection without the use of metal fastening screws. Can also be easily permanently removed in applications where not needed.

https://lithium-car-battery.3dcartstores.com/assets/images/bullet.gif

Fully RoHS Compliant - It is fully compliant and is better for the environment and future generations.

https://lithium-car-battery.3dcartstores.com/assets/images/bullet.gif

Built-in coil suppression - Saves you THE engineering time and parts cost to add external coil suppression.

https://lithium-car-battery.3dcartstores.com/assets/images/bullet.gif

Clear & Precise Specifications – No guessing to see if the contactor will work in your application.

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. For less than 100A, standard UL recommended cable sizes are assumed.
 
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 ECPC 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 ECPC.

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 ECPC for assistance

Application Information:

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.

The use and the manner of use of controller products shall be the responsibility of the customer. The customer covenants and agrees to indemnify and save harmless ECPC in respect to any loss or damage that may arise through the use by the customer or others, of any of ECPC’s products.
