Vapor relays & contactors

Designed, Tested and Proven for Critical Applications

From rail passenger cars and locomotive control and starting circuits to earth moving
equipment, Vapor relays and contactors have established a reputation for quality and reliability where dependable control of DC circuits is required. Performance-proven in thousands of applications worldwide, Vapor relays and contactors meet or exceed stringent qualification requirements of major locomotive and rail passenger car builders and heavy machinery manufacturers.
 
 
Units are in daily service on U.S. Class 1 railroads, the New York City Transit Authority, the Chicago Transit Authority, the Toronto Transit Commission and other railroads and transit agencies around the globe.
 

Extended Service Life

Vapor designs incorporate the highest quality components and materials to provide long life with minimum maintenance. Control relays provide from 1 to 2 million cycle load life and 10 million mechanical cycles. Contactors provide up to 5 million mechanical cycles.
 

Shock and Vibration

All products have been designed for an extended service life on moving equipment, and will withstand continuous conditions
of shock and vibration.

Custom Designs

A wide selection of standard relays and contactors is available. In addition, Vapor can design and manufacture units to meet
specific requirements.
 

Minimum Maintenance

Rugged enclosures, accessible designs, quality materials and controlled manufacturing processes all contribute to minimizing
maintenance problems and expense.
 

Compact, Lightweight Units

As units are engineered for a particular purpose, application and/or specification, they represent the lightest, most compact
design possible.

Computerized Testing

All relays and contactors are thoroughly tested during the manufacturing process using computerized test equipment. Electronic records verify the specification compliance
of every unit.
