Capacitor contactor CEM7,5CN.11-230V-50Hz, 230V, 50Hz 004643800

Capacitor contactor – incorrect reactive power switching

The CEM7,5CN.11-230V-50Hz capacitor contactor is a key element in reactive power compensation systems, providing effective capacitor switching and optimizing electrical network parameters. This device, manufactured by ETI Polam, is used in both industrial and commercial installations where voltage stabilization and energy loss reduction are a priority.

This model is distinguished by its solid construction and reliable operation, which translates to a long service life and minimal operating costs. It uses screw connections for the main contacts, which simplifies installation and ensures a secure electrical connection. This allows installers to quickly and efficiently integrate the contactor into existing infrastructure.

#### Characteristics and application

The CEM7,5CN.11-230V-50Hz contactor is designed to operate with a control voltage of 230V AC (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. The rated reactive power of 7.5 kvar makes it ideal for compensating small inductive loads.

* Reactive power compensation: Improving the power factor (cos φ) in electrical installations.

• Energy loss reduction: Reducing currents flowing in the network and minimizing losses in cables and transformers.

• Voltage stabilization: Maintaining a stable voltage in the network, which improves the quality of operation of electrical devices.

• Device protection: Reducing the load on electrical devices by reducing harmonic currents.

• Automation: Possibility of integration with automatic reactive power compensation control systems.

The contactor design allows it to be mounted in standard electrical switchboards, and its compact dimensions make installation easy even in limited spaces. This means that both installers and end-users can count on convenience and efficiency.

#### Construction and operating parameters

This contactor is characterized by high quality workmanship and the use of durable materials. It has a solid housing that protects against external conditions and ensures safe operation of the device. It is worth paying attention to the precisely made main and auxiliary contacts, which guarantee reliable switching of electrical circuits.

* Type of control voltage: AC – allows easy integration with existing control systems based on alternating voltage.

• Number of auxiliary contacts: Two contacts (normally closed and normally open) allow for the implementation of additional control or signaling functions of the contactor status.

• Screw connection: Provides a secure and durable connection of electrical wires without the need for specialized tools.

• Rated reactive power: 7.5 kvar – optimal value for compensating small inductive loads in electrical installations with a voltage of 400V (50Hz).
