Leviton Enhances Line of PowerSwitch(TM) IEC 309 Mechanical Interlock Devices Adding Safety, Convenience, Ease of Installation

Little Neck, NY, February 14, 2003 -- Leviton's Industrial Products Division has enhanced its line of IEC 309-1 and 309-2 PowerSwitch(TM) Mechanical Interlock devices with features that add greater reliability, durability, and ease of installation. These North American IP67 Watertight devices combine a pin and sleeve receptacle with a safety disconnect switch into a single unit that safeguards end-users and their equipment by preventing the haphazard making/breaking of "under load" electrical connections. The PowerSwitch Mechanical Interlock devices are now available in 20, 30, 60, and 100 amp non-fused configurations and new 20, 30, and 60 amp fused configurations. All configurations are contained in rugged, non-metallic NEMA Type 3R, 4X, and 12K Valox® 357 enclosures.

Enhancements to the line include a new enclosure design that comfortably fits within an I-Beam and a downward facing receptacle angled to protect the receptacle-to-plug connection. The bottom-hinged cover, a Leviton exclusive, provides a handy resting place for tools and reduces cover damage during installation and maintenance. The new high-visibility red "pistol grip" handle includes the integrated lockout feature meeting OSHA's safety regulations while providing visual confirmation of the switch's status.

Internal design enhancements include fused versions in 20, 30, and 60 amps featuring integrated, "finger-safe" fuse holders that accept "Class J" Time-Delay fuses. All models now include 1-factory-installed auxiliary contact for remote line management and power monitoring, making these devices ideal for automated factory applications in the chemical processing, plastics, packaging, and metal production industries. Space is provided for an additional auxiliary contact, maximizing the device's utility.

For easier installation, the new mechanical interlock devices feature generous wiring space for drip loops and are supplied with a pre-wired grounding plate connected to the factory-installed liquid-tight hub.

The new enclosure also allows end users to choose their preferred mounting method, with or without mounting feet. For faster trouble-shooting and maintenance, a circuit identification pad is conveniently located just above the receptacle.
