Modular contactor with manual control 20A 2 normally closed contacts (1 module, 2-speed) RD 20-20-R-24V AC/DC 002464043

Modular contactor with manual control – reliable circuit switching

This modular RD 20-20-R-24V AC/DC contactor is a compact and versatile device designed for safe and efficient switching of electrical circuits. It is ideal for both home and commercial installations where reliability and ease of use are required. The design with manual control allows for direct control over the circuit, which is particularly useful during maintenance or failure.

Construction and application

This contactor is designed for mounting on a TH35 rail, occupying only one module. It has two normally closed contacts, making it suitable for many applications, such as switching lights on and off, controlling small motors, or in home automation systems. The ability to manually control is an additional advantage – it allows operation even in the event of a control voltage failure. The rated operating voltage is 230V AC, and the rated current is 20A, ensuring compatibility with most standard electrical installations.

Key features and benefits

• Universal control voltage: The ability to power with both AC and DC voltage (230…230V) increases installation flexibility and allows adaptation to different working conditions.
• Manual controller: The built-in slider for manual operation enables direct control over the circuit, which is particularly important during servicing or power failure.
• Compact size: Occupies only one module on a TH35 rail, saving space in the distribution board.
• High reliability: Made of high-quality materials, guarantees long-lasting and trouble-free operation.
• Protection class IP20: Provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm – standard protection for devices mounted inside distribution cabinets.
• Two normally closed contacts: Allow switching of circuits with different loads.
• Wide range of applications: Ideal for controlling lighting, motors, heating systems and other electrical devices.

It is also worth mentioning the ETIM EC001653 classification (installation contactor), which facilitates product identification in electrical catalogs and ensures compliance with industry standards. This contactor does not have the possibility of expansion with additional equipment, which translates into a simple construction and reliable operation.
