Standard Basic Lock is suitable for use with a wide range of electrical switchgear. Lock is available in Pin type ( I#L ) and Figure Type ( I#S ) with standard and customised accessories to suit most suppliers of switchgears equipment (#: L for Brass and S for Stainless Steel). The Standard version comes with a 9.5 mm square shaft or a 14.5 mm round shaft on the rear side, which engages with the actuating lever on the switchgear/isolator. Power isolation is done by turning the key, which can be transferred to an access lock to enforce an interlocking sequence. The standard basic lock is also used to ensure that multiple power suppliers are not connected to a common busbar. Please contact PSPC for standard suggested schemes.
