DC Contactor Families
DC contactors are electromechanical products developed and produced for the purpose of high current switching between a power source and a load.

A family is a group of products where each series is related by a specific technological design concept. Typically, one series of a Family will differ from another by the diameter of the housing and other performance characteristics.
PowerSeal Family
(Hydraulic Power Packs, RV, Heavy Truck Starting and Grid Heaters, and Lawn & Garden Applications)
IP66 and IP67 certified


PowerSeal Specifications:
Intermittent Duty - Carry Current 150 amps, Inrush 800 amps

Available in 12 volts and 24 volts

The power you need for high amperage applications along with the sealed construction gives the PowerSeal its name. The PowerSeal's unique design allows it to be used in tough environmental conditions.

Plastic Housing Family
(Lawn and Garden Applications)


Plastic Specifications:
Intermittent Duty - Carry Current 200 amps, Inrush 300 to 600 amps depending on model
Continuous Duty - Carry Current 100 amps, Inrush 400 amps

Available in 12 volts

Strong, high temperature-resistant housings surround these DC Contactors, resulting in high efficiency DC Contactors. Produced in a variety of sizes and pole configurations, these Plastic DC Contactors are ideal for high volume, cost-sensitive applications.

Continuous Duty PowerSeal Family
(Electric Vehicles, Utility Vehicles, and Golf Carts)
IP66 and IP67 certified


PowerSeal Specifications:
Continuous Duty - Carry Current 150 amps, Inrush 800 amps (depending on voltage)

Available in 12 volts, 15 volts, 24 volts, 36 volts, and 48 volts

It is the first contactor designed specifically for electric vehicles and applications requiring tough environmental conditions. The environmental seal is the centerpiece of the optimized design for higher performance and lower cost.

High Performance Plastic Family
(ATVs, Utility Vehicles, Snowmobiles, Golf Cars, and Lawn and Garden Applications)


Plastic Specifications:
Intermittent Duty - Carry Current 200 amps, Inrush 300 to 600 amps depending on model
Continuous Duty - Carry Current 100 amps, Inrush 400 amps

Available in 12 volts, 24 volts, and 36 volts

Best case scenario for the worst case conditions. Our High Performance (HP) Plastic DC Contactor Family is designed and built to take the worst and come in first.

Defender Family
(Ag & Construction Equipment, Emergency Vehicles, Fire Trucks)

Defender Specifications:
Continuous Duty - Carry Current 200 amps, Inrush 400 amps

Transient Voltage Suppression (TVS)

Available in 12 volts and 24 volts

The Defender is your main power relay solution, with only one relay switching point. It is designed with built-in Transient Voltage Suppression (TVS) and can handle currents as low as 350 milliamps and as high as 200 amps.

Bear Family
(Golf Carts, Electric Vehciles, Battery Disconnects, Construction Equipment, and other high current applications)


Bear Specifications:
Intermittent Duty - Carry Current 300 amps, Inrush 600 amps

Continuous Duty - Carry Current 225 amps, Inrush 600 amps

Available in 12 volts, 24 volts, 36 volts and 48 volts

This family earned the name the "Bear" because of its strong construction and high current carrying capability. While it is large in size, the Bear provides an economical solution to high current switching applications.

Metal Housing Family
(Military Vehicles, Hydraulic Power Packs, and Golf Carts)

Metal Specifications:
Intermittent Duty - Carry Current 125 amps to 300 amps, Inrush 500 amps to 700 amps

Continuous Duty - Carry Current 125 amps, Inrush 500 amps to 600 amps

Available in 12 volts, 24 volts, and 36 volts

These electromechanical devices utilize a metal casing to surround a DC Contactor, which allows for higher application ratings.

Reversing Polarity (RP) Family
(RV Slides, RV Leveling System, ATV Winch, Truck Tarp Systems, and Boat Lifts)

Reverse Polarity Specifications:
Intermittent Duty - Carry Current 75 amps to 125 amps, Inrush 150 amps to 500 amps

Available in 12 volts and 24 volts

Reversing Polarity DC Contactors provide a cost effective and simple solution for reversing polarity of permanent magnet DC motors. Integrating two DC Contactors into a single housing unit, Trombetta has eliminated many costly materials and streamlined final product assembly and wire connection.
Metal Housing SPDT Family
