Kirk Key PPS Interlock Achieves Power Panel Isolation
Key activated lock with multiple contact arrangements
Kirk Key’s new Power Panel Switch (PPS) interlock provides reliable electrical isolation in a flexible design to fit a variety of equipment configurations. Ideal for switchgear, electrical distribution, and machine guarding applications, the PPS is available in all three of Kirk’s duty series, with six standard contact arrangements, as well as custom configurations.

Suitable for switch ratings of 20, 25, 40, 63, or 100 amps, the rotary style PPS promotes safe work flows by isolating electrical power or switching control circuitry. When the PPS key is turned and released, it can be used in the next sequence of operations such as gaining access to now isolated equipment through a hatch door.
The PPS is available in any of Kirk Key’s three interlock series: the Standard Duty (SD), Medium Duty (MD) and Heavy Duty (HD). The UL and CSA approved PPS is available in an IP65 polycarbonate enclosure. The MD and HD series will soon be available in an optional IP65 panel mounted version as well.
