24-Hour Three-Channel Digital Timer
The Intermatic PE153 is a wall-mounted electronic timer that provides three independent SPST channels for 120 or 240 volt AC circuits. It is suited for commercial or light-industrial installations that require automated on/off control of lighting, pumps or HVAC equipment across a full day.
Metal NEMA 3R Enclosure For Wall Mounting
The grey metal housing carries a NEMA 3R rating and mounts directly to a wall, simplifying installation in outdoor or damp locations. Wiring must accommodate three poles at 20 amps each, and the 36-hour backup only preserves programmed events during brief power interruptions.
Six Programmable Events Over 24 Hours
Up to six on/off events can be scheduled with a minimum setting of one minute and a maximum span of 24 hours. The timer operates reliably from -40 to 155 degrees Fahrenheit, maintaining consistent switching performance during continuous daily cycling without drift.

Questions about this item
How do I verify the timer is operating correctly after wall-mounting and wiring it to 120/240V AC?
Apply power and confirm the display lights up; program a 1-minute on/off event on one of the three SPST channels and watch the load switch at the set time — the 20 A contacts should open and close cleanly.
What does the PE153 include and what must I supply separately?
The unit ships as a complete NEMA 3R metal enclosure with the digital timer and three-pole contactor built in; you only need to provide mounting hardware, conduit fittings and the 120/240V supply conductors.
Which voltage rating should I select for a 240 V single-phase circuit?
The PE153 is rated 120/240V AC, so the same model works on either 120 V or 240 V supplies — choose this one unit for 240 V applications.
