High-inrush switch module provides 4 independent channels of switching for high-inrush loads such as motors, HID lighting and fluorescent ballasts, as well as incandescent, low-voltage and neon/cold cathode lighting. Each channel is rated for 16A or 1 HP, with total module rating of 64A when fed from four separate 16A feeds. Air-gap relays are provided on every channel output allowing individual circuits to be serviced without disabling entire module. An override feature allows each channel to be set to preset state during setup. In event that Cresnet communications should be disrupted for any reason, simple contact closure can be used to activate override presets on global or semi-global basis.
