Intermatic T10404R 40A Mechanical Pool Timer
The Intermatic T10404R is a 40-amp mechanical time switch with enclosure, designed to control high-voltage equipment such as pool pumps, heaters, lighting circuits, and commercial loads. This model operates on 208–277V and features a DPST (double-pole, single-throw) switching mechanism capable of handling demanding electrical applications.
Trusted for decades in pool and commercial installations, the T10404R provides reliable, mechanical scheduling without relying on electronics or software.
Why Mechanical Timers Still Matter
Mechanical timers remain a preferred choice for pool equipment because of their durability, simplicity, and resistance to power surges. Unlike digital timers, mechanical timers continue operating accurately in harsh outdoor environments.
Common reasons to use or replace a mechanical timer include:
-
Reliable on/off scheduling without programming complexity
-
High load capacity for pumps and motors
-
Proven longevity in outdoor installations
-
Simple visual confirmation of operating schedule
The T10404R is especially well suited for installations where consistency and durability are critical.
Designed for 208–277V Applications
This timer is specifically rated for 208–277V systems, making it ideal for commercial pools, multi-family properties, and higher-voltage residential equipment pads. The DPST switching allows both legs of the circuit to be controlled simultaneously, improving safety and compliance.
The included metal outdoor-rated enclosure protects internal components from weather and debris.
Common Pool Equipment Applications
The Intermatic T10404R is commonly used to control:
-
Single-speed and two-speed pool pumps
-
Booster pumps
-
Pool and spa lighting circuits
-
Heaters and auxiliary equipment
Installation should be performed by a qualified electrician or pool professional familiar with high-voltage wiring.
