Hubbell Wiring Device-Kellems Announces Non-Metallic Labelless Disconnects
Tuesday, July 07, 2015

Shelton, Conn. – July 7, 2015Hubbell Wiring Device-Kellems has added to its line of Circuit-Lock® Non-Metallic Disconnects a new labelless version that is made to withstand harsh environments even better than before.


The permanent markings are made by a unique laser marking system that permanently changes the color of the plastic.  The devices are engineered to hold up to frequent washdowns, hot and high-pressure water sprays, UV light, and harsh cleaning agents. To ensure that the cover’s markings will last through use in tough conditions, they underwent several tests for accelerated weathering and abrasive scratching – and passed with flying colors.

In addition to the new labelless covers, the Circuit-Lock® Non-Metallic Disconnects continues to offer:


  • Improved SCCRs (short-circuit current ratings). Without any design changes, UL determined that Hubbell’s Circuit-Lock® Non-Metallic Disconnects are capable of a 65kA rating when protected by Class J fuses.
  • Improved water and dust ingress protection. Completing third-party confirmation for IP69k performance, the disconnects passed rigorous tests of endurance against extremely hot and high-pressure water streams.


As a result of these features, the new labelless Circuit-Lock® Non-Metallic Disconnect is certified by the National Sanitation Foundation (NSF) for use in hygienic applications, such as food and beverage processing.


“The labelless version of the Hubbell Circuit-Lock® Non-Metallic Disconnects offer all the same great features they always have – the best just got better,” says Greg McAleer, senior product manager for Hubbell Wiring Device-Kellems. “Between this new labelless feature and the product’s improved environmental ratings these disconnects will withstand even the roughest of environments.”
