ABB IEC 60309 Plugs, Connectors Now IP69K Rated

Connectors work in applications requiring liquid ingress protection

ABB IEC 60309 plugs and connectors are now IP69K rated, which is the highest dust and liquid ingress rating attainable, making the connectors ideal for applications requiring liquid ingress protection. Examples include wash-down operations in food processing plants, dairy farms, breweries and other applications.

“In environments like the food processing industry, which require routine high-pressure wash downs, electrical components are vulnerable to liquid ingress of both water and chemicals,” said Camilo Delgado, product marketing director at ABB. “The IP69K rating offers complete assurance that our ABB IEC 60309 pin and sleeve devices have been certified to be both durable and resistant, and conform to the highest ingress protection rating.”

The IP69K tests entailed placing the ABB IEC 60309 devices on a turntable at a speed of approximately 5 rpm. They were then sprayed at close range at a rate of 4 gpm with water pressure between 1,160 and 1,450 psi at a temperature of 176 degrees Fahrenheit. The water nozzle was held at a variety of angles, between 4 in. and 6 in. from the product. To attain the IP69K rating, the product being tested must completely resist liquid ingress.

ABB IEC devices are also durable and offer superior cable strain relief and pullout prevention. Safety measures incorporated into the ABB IEC 60309 connectors include a double cable clamp system to prevent cable detachment and two screws at each terminal to maintain electrical connection.

The housing is designed for maximum durability in harsh operating conditions, and is made from a self-extinguishing (UL 94V0), ultraviolet (UV)-resistant (UL 746 F1) Valox 357 material. The material is also highly resistant to chemicals like mineral and organic acids, organic solvents and petroleum. Fiberglass-reinforced nylon is used for the contact carrier on devices rated between 60 and 125 amps. A self-cleaning design keeps debris or dirt out of the electrical contacts to reduce down time.
