It controls electrical loads up to 40 amps per pole and operates on 120 VAC at 60 Hz with a DPST switch configuration. The unit supports up to 10 ON\/OFF settings per day and includes a skip-a-day function, allowing operators to omit scheduled cycles on days when loads are not needed. A spring-wound carry-over backup maintains schedule integrity for up to 16 hours without power, restoring at a rate of 1 hour for every 2 hours offline. The enclosure is an outdoor-rated Type 3R metal housing suitable for exposed installations.\u003c\/p\u003e\n\u003cp\u003eThe 173CR is appropriate for a wide range of load types across residential, commercial, and industrial settings. Typical applications include indoor and outdoor lighting control, pool heaters, pumps, blowers, fans, filters, conveyors, electric fences, and signs. It is compatible with LED and HID lamp loads. The unit is well-suited for panel integrators and machinery and pump control scenarios where reliable daily scheduling with day-skip capability is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSkip-a-day function with three skipper screws included to omit scheduling on up to three days\u003c\/li\u003e\n  \u003cli\u003eUp to 10 ON\/OFF operations per day with a minimum interval of 1 hour\u003c\/li\u003e\n  \u003cli\u003eSpring-wound carry-over backup protects schedule for up to 16 hours without power\u003c\/li\u003e\n  \u003cli\u003eOutdoor Type 3R metal enclosure rated for exposed installations\u003c\/li\u003e\n  \u003cli\u003eManual override capability included\u003c\/li\u003e\n  \u003cli\u003ecULus and cCSAus certified; UL916 file number; LED rated\u003c\/li\u003e\n  \u003cli\u003eAccepts wire sizes from 14 AWG to 8 AWG via terminal wiring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with LED and HID electrical loads.
