Timer insulators help protect electrical timer components by maintaining separation around switch contacts and energized hardware. The Intermatic Double-Pole Switch Timer Insulator (124-00157) is a replacement insulator for compatible Intermatic double-pole switch timer applications. This part may be needed when an insulator is cracked, missing, heat-damaged, or removed during service and cannot be safely reused. Restoring the correct insulator helps support safer timer operation and protects the integrity of the electrical assembly during continued equipment use. Replacement insulator for compatible Intermatic timers Designed for double-pole switch applications Helps maintain separation around electrical contacts Useful when original insulation is damaged or missing Supports safer timer service and operation
