Safety Start-Up Power Cords

Wire Leads × Wire Leads

After shutting off power to equipment during a power failure, these cords must be manually reset, preventing unexpected equipment start-up. Use them to replace three-wire power cords on equipment driven by small single-phase motors. The industry designation is SJTO, so the insulation resists oil.
