4. AUTO OFF/ON DELAY & MANUAL START/STOP

The timer provides Auto OFF/ON Delay operation for applications where equipment needs to run for a preset duration before switching OFF. The MANUAL function allows convenient manual starting and stopping, while AUTO mode enables programmed automatic operation.

5. DIN RAIL MOUNT, LCD DISPLAY & SILICON KEYPAD

Designed for convenient installation inside electrical panels and distribution boards. The DIN rail mounting design, compact body, clear LCD display and silicon keypad provide easy installation, programming and operation.

PRODUCT DESCRIPTION

The LEYDEN LE363AT 63A 380–440VAC Three Phase Digital Timer Switch is a programmable digital timer designed for automatic time-based control of suitable three-phase electrical loads.

The device offers multiple operating functions, including Real Clock Based ON/OFF Programming, Auto OFF/ON Delay, Cyclic ON/OFF Timer and Manual Start/Stop Operation.

With up to 24 ON/OFF programs per day, users can set multiple automatic switching schedules according to the actual clock time. The weekly programming function allows operation on selected days or all seven days of the week: MO, TU, WE, TH, FR, SA and SU.

The Cyclic ON/OFF Timer allows the connected load to operate repeatedly according to preset ON and OFF intervals from approximately 1 second to 24 hours. This function can be useful for fogger systems, hydroponic pumps, irrigation systems, ventilation and similar repetitive automation applications.

The Auto OFF/ON Delay function can be used for applications where a connected device needs to operate for a preset time before automatically switching OFF, such as suitable motor applications, geysers, charging equipment and other compatible loads.

The Manual Start/Stop function provides convenient manual control, while AUTO mode allows the programmed schedule to control the load automatically.

The LE363AT features a 63A rating, 380–440VAC three-phase operation, LCD display, silicon keypad, compact design and DIN rail mounting for convenient installation in suitable electrical panels and control systems.

IMPORTANT: Installation and electrical connection must be carried out by a qualified electrician or trained electrical professional. Always use proper-size copper wire, suitable protection devices and wiring according to the connected load and applicable electrical standards.

OPERATING MODES

1. REAL CLOCK BASED ON/OFF PROGRAMMING

Use this mode when you want the connected electrical load to automatically turn ON and OFF at specific clock times.

Example:

Program 1: ON at 08:00 → OFF at 12:00
Program 2: ON at 14:00 → OFF at 18:00

The timer supports up to 24 ON/OFF programs per day.

2. AUTO OFF / ON DELAY MODE

This mode is suitable when the connected load needs to operate for a preset time and then automatically switch OFF, or when delayed operation is required.

Suitable applications may include:

Suitable motor applications
Geysers
E-bike charging
Charging systems
Electrical equipment
Other compatible loads requiring timed operation

3. CYCLIC ON/OFF MODE

The Cyclic ON/OFF mode repeatedly switches the connected load ON and OFF according to preset ON and OFF intervals.

Suitable applications may include:

Fogger systems
Hydroponic systems
Irrigation systems
Hydroponic pumps
Ventilation systems
Repetitive automation systems
Other suitable electrical loads

IMPORTANT APPLICATION NOTE: The suitability of the timer depends on the actual load type, starting current, motor rating, wiring, protection devices and installation conditions. For motors, compressors, pumps and other high-inrush or inductive loads, use a properly rated contactor, overload relay and suitable protective devices as required by a qualified electrician.

INSTALLATION & SAFETY INSTRUCTIONS

⚠️ IMPORTANT SAFETY WARNING

Installation must be carried out by a qualified electrician or trained electrical professional.
Always use good-quality copper wire for electrical connections.
Select the proper wire size according to the connected load and applicable electrical standards.
Use appropriate MCB, MCCB, fuse, overload protection and other safety devices as required.
Ensure all electrical terminal connections are properly tightened.
