Capacitor contactor CEM25CN.10-230V-50HZ, 230V, 50Hz 004645130

Capacitor Contactor – Incorrect Reactive Power Switching

The CEM25CN.10-230V-50HZ capacitor contactor is a component used to switch reactive power in electrical installations. It finds application in automatic power factor correction (cos φ) systems, improving energy efficiency and reducing losses in the network. This device, manufactured by ETI Polam, is characterized by a solid construction and reliability, which translates into a long service life and minimal risk of failure.

Construction and Application

This contactor is designed to operate at 230V and a frequency of 50Hz. It has three normally closed main contacts and one normally open and one normally closed auxiliary contact, allowing it to be integrated with various control and signaling systems. Screw connection of the main contacts ensures secure and durable electrical connections. The rated reactive power of 20 kvar makes this contactor suitable for use in medium-power installations.

• Reactive Power Compensation: A key element of power factor correction systems, reducing network load and energy costs.
• Automation: Cooperation with controllers allows for automatic switching of capacitors depending on demand.
• Application in Industry and Construction: Ideal for workshops, production halls, offices and other facilities with a variable load characteristic.
• DIN Rail Mounting: Modular design simplifies mounting on a standard TH35 rail.

Technical Characteristics and Benefits

The CEM25CN.10-230V-50HZ contactor is distinguished by its high reliability and precise operation. The use of high-quality materials guarantees long-term operation even in harsh environmental conditions. This allows installers to be confident in the stable operation of the reactive power compensation system, and end-users – to lower electricity bills and improve power quality. Having normally open and normally closed auxiliary contacts provides additional control and monitoring possibilities of the device status within a larger automation system.
