The ilS4-121 electrical load switcher safely switches high amperage equipment with low cost timer or controller. Used with optional on-delay timer, the iIS4-121 activates its outlets in sequence to protect circuits from overload at equipment startup.

  • Description

    Plug load switcher sense cord in a timer or a controller to increase your capacity. When the sense cord is powered up, the iLS4-121 switches on its 4 outputs which each of them a device can be connected.
    • 4 x 120 V outputs, 15 A
    • Pilot lamp activation
    • One 15 A circuit breaker per outlet

    Fed by a 120 v 40 A circuit breaker, the iLS4-121 will feed four 1000 W lights, three 1,500 W heaters or three 15,000 BTU air conditioners for about 3.75 T of refrigeration. It is also possible to connect 2 iLS4-121 modules on a same circuit and feed height 400 W lights.
    • 120 V, 40 A load capacity
