Modular contactor 20A normally open and normally closed contact (1 module, 2-pole) R 20-11 24V 002461221

Modular contactor – reliable circuit control

This R 20-11 24V modular contactor is a compact and efficient solution for remote control of various electrical circuits. It will work both in home and industrial installations where reliability and precision are required. Ideal for controlling lighting, heating, ventilation, as well as devices with motors. Compatibility with modular equipment simplifies mounting in standard distribution boards.

Construction and application

This contactor is designed to operate in AC (alternating current) systems with a rated voltage of 230…400V. Its construction based on solid materials guarantees long-lasting and trouble-free operation. It has one normally open (NO) and one normally closed (NC) contact, which provides flexibility in configuring control circuits. The control voltage of 24V AC ensures compatibility with popular automation systems. The rated operating current is 20A, which allows for handling most standard loads.

Key features and benefits

• Compact size: A width of only 1 module saves space in the distribution board.
• Versatility: Suitable for controlling various loads – from lighting to motors.
• Reliability: Made of high-quality materials, ensuring long life and stable operation.
• Safety: Protection class IP20 protects against accidental contact and the ingress of solid objects larger than 12.5 mm.
• Easy installation: Compatible with DIN mounting rails, which facilitates installation and replacement.
• Contact position indicator: Allows for quick visual control of the contactor status (on/off).
• Wide operating temperature range: From -40°C to +60°C allows use in harsh environmental conditions.
• Compliance with standards: Meets the requirements of PN-IEC 60947-4-1, which guarantees the safety and quality of the product.

Technical parameters in practice

Rated current of 20A means that the contactor is adapted to handle devices drawing up to 20 amps of current without risk of damage. The control voltage of 24V AC is commonly used in building and industrial automation systems, which ensures easy integration with existing installations. Lack of manual operation option (manual operation slider: false) increases safety, eliminating the risk of accidental switching on or off of the circuit.
