    Mitsubishi Electric CTU Capacitor Trip Device (SL Latched Contactors)

    Mitsubishi Electric CTU Capacitor Trip Device (SL Latched Contactors)

    Mitsubishi Electric CTU capacitor trip device that trips MSOL/SL mechanically latched contactors after a power failure using energy stored in a capacitor.

    Key features

    • Trips the latched contactor within the specified time after a power failure (charge for 10 s or more at rated voltage)
    • Trip operation possible up to 30 s after power loss
    • Operating voltage AC100V type (100-110V 50/60Hz) or AC200V type (200-220V 50/60Hz)
    • Type selected by latched contactor frame: A (T21-T50), B (T65-T100, N125-N400), C (N600, N800)
    • Uses an electrolytic capacitor - check capacitance periodically
