Intermatic ET90115C Astronomic Timer

The Intermatic ET90115C is an electronic timer designed for industrial electrical control and automation. It features an astronomic operation mode that tracks sunrise and sunset across a 365-day calendar. The unit is housed in a gray metal enclosure with snap-in mounting for panel installation.

Suits automated lighting and load scheduling

This timer suits facilities that need automatic lighting or equipment control based on daily astronomical events. It provides a single channel with SPDT contact form for switching one circuit. Buyers who need multiple independent channels or more than 4000 programmable events should look at a different controller.

30 A switching at 120-277 V AC

The timer switches up to 30 amps across a 120 to 277 V AC supply range. It handles motor loads rated at 1/4 HP normally closed and 1 HP normally open at 120 V, or 1/2 HP normally closed and 2 HP normally open at 240 V. Pulse duration is adjustable from 1 second to 24 hours.

Questions about this item

What is the maximum sustained load the SPDT contact can switch at 120 V AC?

The SPDT contact is rated for 30 A resistive, 1/4 HP on the normally closed side and 1 HP on the normally open side at 120 V AC.

How much heat or noise does the metal enclosure produce during continuous 24-hour operation?

The unit has no moving parts or fan, so it runs silently and generates only minimal heat from the relay coil under load.

What supply voltage must already be present at the installation point for this timer to operate?

The timer requires a 120 to 277 V AC supply connected to its power terminals before it can control any circuit.
