Brand: Intermatic | Manufacturer Part Number: T104M | Big Frog Supply SKU: T104M
Product Overview
The Intermatic T104M is a mechanism-only 24-hour mechanical time switch for controlling compatible 208–277 VAC two-pole loads. Its DPST switching arrangement is commonly used for pumps, motors, heaters, lighting, and other approved equipment where a matching Intermatic enclosure is already installed or will be supplied separately. The dial repeats the same schedule each day, and the manual override allows temporary operation without moving the programmed trippers.

Compatibility and Installation Notes
The T104M fits many compatible Intermatic enclosures, but the enclosure, voltage, mounting, wiring, and connected load must be confirmed for the specific installation. The existing custom specification that described an outdoor plastic enclosure did not apply to this mechanism-only SKU and has not been repeated in the customer-facing copy. Installation involves hazardous line voltage and should be completed by a qualified person with power disconnected.
Frequently Asked Questions
Does the T104M include an enclosure?
No. It is the mechanism only.
What voltage does it use?
The clock mechanism is rated for 208–277 VAC at 60 Hz.
What switching arrangement does it use?
The T104M uses DPST switching for compatible two-pole loads.
Why Buy This Product from Big Frog Supply?
The T104M is the correct replacement when the enclosure remains serviceable and only the higher-voltage DPST mechanism is needed. Big Frog Supply clearly separates it from complete T104 timer assemblies and avoids carrying over enclosure specifications that do not belong to this SKU.
