Schneider Electric RTX-133 Time Relay 2P 5A 1-12min 220-230V AC/DC

The Schneider Electric RTX-133 is a high-quality 2-pole time relay engineered for precise time-controlled switching in electrical circuits. Operating on a 220-230V AC/DC supply, this device provides reliable performance for systems requiring a delayed switching function. With a rated current of 5A and an adjustable time range between 1 and 12 minutes, it offers the flexibility needed for various automation tasks in industrial and residential environments.

Advantages

The primary benefit of the RTX-133 time relay is its robust construction, which guarantees long-term operational stability even in demanding electrical control systems. Its dual-pole configuration allows for versatile circuit management, while the wide voltage compatibility ensures seamless integration into existing infrastructure. The adjustable timing mechanism is intuitive, allowing users to set precise intervals without complex programming, making it an efficient solution for time-based automation.

Suitable for

• Building automation systems for lighting control
• Industrial process timing and sequence management
• Ventilation and fan control systems
• Delayed activation of electrical equipment

When it may not be suitable

This relay is not designed for applications requiring millisecond precision or extremely short switching intervals, as its range is limited to 1-12 minutes. It is also not suitable for high-power loads exceeding the 5A rated current capacity without the use of additional contactors or auxiliary relays.

Key specifications

• Number of poles: 2
• Rated current: 5A
• Operating voltage: 220-230V AC/DC
• Time adjustment range: 1 to 12 minutes

How to use

Installation should be performed by a qualified professional in accordance with local electrical safety standards. The relay is typically mounted on a standard DIN rail within an electrical distribution board. Once mounted, connect the power supply to the designated input terminals and wire the controlled load through the output contacts. Use the adjustment dial on the front of the unit to set the desired delay time within the 1-12 minute range before energizing the circuit.

What to consider before purchase

• Ensure the load current does not exceed 5A
• Verify that the control voltage matches the 220-230V AC/DC specification
• Confirm that the required timing interval falls within the 1-12 minute range

Usage recommendations

Regularly inspect the terminal connections to ensure they remain tight and free from oxidation. Avoid installing the device in environments with excessive moisture or extreme temperatures to maintain optimal relay longevity.
