North Canton, Ohio — April 7, 2015 — Kirk Key has developed a reduced-size mechanical bolt interlock for smaller stature breakers.
Modeled on the KIRK Standard Duty series Type F, the smaller Type FF ensures that workers follow a pre-determined sequence of operation to safely access electrical switchgear.
Manufactured with a brass lock housing and cylinder, the Type FF has a ¾-inch travel, with a smaller diameter ½-inch stainless steel lock bolt to better fit in smaller cabinets.
The proprietary seven-pin tumbler key design is unique to Kirk and not available commercially, minimizing the risk of circumventing safety sequences with duplicate keys.
The Type FF footprint is 2-by-1¼ inches and is generally flat or face mounted with ¼-inch mounting bolts through the front of the housing. The reduced footprint of the Type FF is about 50 percent smaller and nearly 60 percent lighter, allowing for greater clearance around the breaker within the switchgear assembly.
The Type FF, in conjunction with Kirk’s current comprehensive line of Standard Duty bolt, electro-mechanical, access, transfer, and cylinder interlocks, creates a complete trapped key interlock system for switchgear and other process safety applications.
