TORK EWZ120 Astronomic Timer Overview
The TORK nsi EWZ120 is an electronic timer with astronomic operation across a 7-day schedule. It provides a single channel and SPDT contact form rated for 30 A at 120 to 277V AC. The tan plastic enclosure carries a NEMA 3R rating for surface mounting.
Installation Power & Wiring Checks
Verify the supply voltage falls within the 120 to 277V AC range and that the load does not exceed 30 A. Confirm the circuit can accommodate 1 HP at 120V or 2 HP at 240V if driving a motor. Ensure a surface mounting location is available for the plastic enclosure.
Fit for Scheduled Lighting & Load Control
Suits installers needing automated on/off control for lighting or equipment with up to 20 programmed events. The 4-day capacitor backup maintains timing during short power interruptions. Buyers requiring more than one independent channel or a different contact configuration should look at other models.

Questions about this item
What comes with the EWZ120 timer and what must I supply?
The unit includes the electronic timer with a plastic NEMA 3R enclosure and a capacitor providing four days of backup. You must supply the 120–277 V AC power feed and the load wiring for the single SPDT channel.
Which voltage version should I choose for a 120 V or 240 V circuit?
The same model operates on 120 to 277 V AC; at 120 V it handles 1 HP and at 240 V it handles 2 HP, so no separate version is needed.
What does the 30 A rating mean when the timer is installed in a panel?
The single-pole SPDT contact is rated for 30 A resistive load at 120–277 V AC, allowing direct control of loads up to that current without an external contactor.
