Analogue Timer Switch IH 24H with 3 Modules SRM 1C-16A

The Schneider Electric Acti9 IH CCT16364 analog time switch is a daily mechanical timer designed to automatically switch electrical circuits on and off according to a preset schedule. It operates on a 24-hour cycle, features 1 channel and a contact rated up to 16 A, and allows minimum programming intervals of 15 minutes, making it a simple and reliable solution for automating lighting, heating, and other electrical loads.

Reference CCT16364 corresponds to the IH 24h 1C SRM version, where SRM indicates that the device operates without power reserve. It is powered at 230 V AC and occupies 3 modules of 18 mm in the electrical panel. Programming is carried out directly using the segments on the front dial, with no software, digital display, or external devices required.

24-hour daily programming

The Acti9 IH CCT16364 uses a mechanical dial that represents the 24 hours of the day. The user can define the on and off periods using the segments integrated into the timer itself.

Once set, the program repeats automatically every 24 hours. This makes it especially suitable for installations where the same operating schedule needs to be repeated daily.

• Cycle duration: 24 hours.
• Number of channels: 1.
• Number of programming segments: 96.
• Minimum switching interval: 15 minutes.
• Maximum number of switchings: up to 48 on and 48 off operations per cycle.

Simple analog programming using segments

Unlike a digital time switch, the CCT16364 is configured entirely mechanically. The segments distributed around the dial allow you to select the periods during which the load should remain on or off.

The current time is set by turning the dial until the corresponding time is aligned with the indicated position. This system is especially practical for installations where a simple, intuitive daily timer without electronic menus is required.

Automatic operation and manual control

The time switch includes front controls that allow the output status to be changed manually without altering the programmed schedule.

The device can operate in different modes:

• Automatic operation: the load switches on and off according to the programmed segments.
• Manual on: allows the load to be switched on in advance.
• Manual off: allows the load to be switched off in advance.

This manual override is useful for testing, maintenance tasks, or temporarily changing the installation status without having to reprogram the schedule.

Switching contact up to 16 A

The Schneider Electric CCT16364 includes a potential-free output contact with a maximum switching current of:

• 16 A at 250 V AC with power factor cos φ = 1.
• 4 A at 250 V AC with power factor cos φ = 0.6.

The actual switching capacity depends on the type of load connected. For loads with high inrush currents or power levels above those directly supported by the time switch, an appropriately sized intermediate contactor may be required.

Suitable for automating lighting and other loads

The Acti9 IH can be used to automate different electrical devices that need to follow a fixed daily schedule. Typical applications include:

• Indoor and outdoor lighting.
• Shop windows and illuminated signs.
• Common area lighting.
• Compatible electric heating systems.
• Ventilation and small auxiliary equipment.
• Pumps and other loads via contactor when needed.
• Retail and commercial building equipment.
• Simple home automation systems.

Without power reserve

The SRM designation identifies this version as a model without power reserve. The CCT16364 does not include a battery to keep the clock running during a power interruption.

For this reason, after a power outage it may be necessary to check and reset the timer clock. The mechanical program defined by the segments remains physically set, but the time dial stops advancing while it is not powered.

For installations where it is essential to keep the time during supply interruptions, a suitable model with power reserve should be selected.

230 V AC power supply

The time switch is designed for operation from a 230 V AC mains supply. Schneider Electric documentation for this reference specifies a supply tolerance of +10% / -15%.

• Rated voltage: 230 V AC.
• Tolerance: +10% / -15%.
• Rated frequency: 50 Hz.

The time mechanism of this version is synchronized with the electrical grid, so it does not use an independent quartz oscillator to maintain time reference.

Modular DIN rail mounting

The Schneider Electric CCT16364 is designed to be installed directly on a DIN rail inside modular electrical panels. Its total width is 54 mm, equivalent to three standard 18 mm modules.

• Width: 54 mm.
• Height: 90 mm.
• Depth: 66 mm.
• Module width: 3 x 18 mm modules.
• Net weight: approximately 0.135 kg.
• Mounting: DIN rail.

This format allows the timer to be installed alongside miniature circuit breakers, residual current devices, contactors, and other modular devices within the same electrical panel.

Quick conductor connection

The device features quick connection terminals and accepts both rigid and flexible conductors. Each terminal can accommodate up to two conductors within the cross-sections specified by the manufacturer.

• Connection capacity: 2 x 0.5 to 2.5 mm².
• Stripping length: approximately 8 mm.

Electrical installation must always be carried out with the power disconnected and in accordance with the wiring diagram provided by Schneider Electric.

Protection and environmental conditions

The time switch has an IP20 protection rating according to EN 60529 and a protection class II rating when correctly installed in accordance with the manufacturer’s instructions.

• Protection rating: IP20.
• Protection class: II according to EN 60730-1 with proper installation.
• Operating ambient temperature: -20 to 55 °C.
• Color: white RAL 9003.

Simple daily timer for electrical panels

The Schneider Electric Acti9 IH CCT16364 is a practical solution for installations that need to automatically switch loads on and off following the same schedule every day. Its 96 segments allow operating periods to be set with 15-minute resolution, and its 16 A contact can directly control many compatible loads.

Its analog programming, manual operation, 3-module format, and DIN rail mounting make both installation and daily use easy. As the no-power-reserve version, it is especially suitable for applications where keeping time during possible power interruptions is not essential.
