INTERMATIC T103 Electromechanical Timer, 24-Hr Time Setting, 125 VAC, 40 A, 5 HP

Intermatic T103 electromechanical timer automates the activation and deactivation of electrical circuits for controlling lighting, pumps, heaters and other equipment. By enabling users to pre-program ON / OFF schedules, it enhances energy efficiency, security and convenience.

Working Mechanism:

• The timer houses a clock mechanism that runs on electricity. This clock is responsible for tracking time intervals.
• Users set specific time intervals on the timer. These intervals determine when the connected devices should turn on or off.
• The timer motor is also electrically powered that drives the clock mechanism. It advances the clock by rotating a small gear.
• The timer has multiple switches that control the ON / OFF state of connected devices. Trippers and small plastic tabs are inserted on the timer dial next to the desired on / off times.
• As the timer motor turns the clock, the dial with trippers also rotates. When a tripper encounters a switch, it pushes or releases the switch based on its position.
• When a tripper on the dial pushes a switch, it closes the electrical circuit. This allows electricity to flow to the connected device, turning it on.
• As the dial continues to rotate, a tripper on the dial may release a switch. Releasing the switch breaks the circuit, cutting off electricity to the device and turning it off.

Features:

• Intermatic T103 electromechanical timer has a snap-out timing mechanism that simplifies setting adjustments, while the included and additional E054 trippers allow fine-tuning of the timer's ON / OFF schedule.
• It has a manual override that ensures that the set program remains intact while enabling immediate manual control when needed, offering a balance between automation and manual intervention.
• This T103 timer has a steel enclosure with gray enamel finish for resisting corrosion on exposed surfaces and durability.
• It has mounting holes for easy installation on the wall and a 2 pole configuration to enable independent control of two separate circuits.
• This electromechanical timer supports up to 12 ON / OFF cycles per day, enabling intricate scheduling for applications that require frequent changes in operation, such as lighting or heating control.
• It features a high horsepower rating, thereby making it suitable for resistive loads up to 40A per pole at 125V.
• This T103 electromechanical timer features a manual overriding facility that doesn't alter the preset programming.
• It has teeter-type terminals for numerous load connections and can be easily installed in most Intermatic enclosures.

Frequently Asked Questions:

Q. Do mechanical timers consume electricity?

A. The average mechanical timer uses 1 Watt per hour which translates to 24 Watts daily. Typically, a digital timer uses a little bit more energy. About 2 Watts per hour of power are used here.

Q. What are the three main types of timers?

A. The three major types of PLC timers are on-delay, off-delay and retentive on-delay.

Q. What benefits do an electronic timer have over a mechanical one?

A. Both of them operate similarly and are capable of carrying out the same tasks. A mechanical timer is typically constructed as a massive, grey, metal box that may stand out significantly in your home's decor. Mechanical timers are typically larger, last longer and can take more electrical load than a digital timer.

Q. What maintenance is required for this Intermatic T103 timer?

A. Regularly check for proper alignment of trippers and keep the timer clean from dust and debris.

Q. Does this timer help save energy in lighting systems?

A. Yes, by automating lighting schedules, it helps save energy by preventing unnecessary usage during off-peak times.

Q. What is the purpose of the manual on / off override in the T103 timer?

A. The manual override allows immediate control of devices outside the programmed schedule without affecting the set program.

Q. How to surface mount this timer?

A.

• Remove the cover and remove two screws on opposite corners.
• Remove the housing that encases the time switch and the terminal cover away from the base.
• Place a screw through pre-set holes in the base and screw it to the back of the panel or wall.
• Replace the terminal cup and push the timer firmly onto the base.
• Attach the housing and secure it with screws.

Q. Does Raptor Supplies offer other Intermatic electronic timers?

A. Yes, customers looking for electronic variants can choose from Intermatic SPST electronic timers having astronomic programming that offers sunset ON and sunrise OFF settings, eliminating the requirement for separate photo control devices.
