Distribution Electrical Products

Changeover switches, also known as transfer switches or selector switches, are electrical switches that allow the manual or automatic switching between two or more power sources or circuits. They are commonly used in electrical distribution systems, backup power systems, and industrial applications where a reliable and uninterrupted power supply is critical. The primary function of a changeover switch is to transfer the load or power source from one circuit to another, ensuring continuity of power supply during power outages, maintenance activities, or when switching between different power sources. Changeover switches often have three positions: “Mains,” “Off,” and “Generator” (or any other alternate power source). The switch enables users to manually select the power source they want to use, or in some cases, it can automatically detect a power interruption and switch to an available backup power source. Changeover switches come in various sizes and configurations to accommodate different voltage and current requirements. They are typically equipped with robust safety features, such as insulation barriers, arc suppression technologies, and interlocking mechanisms, to prevent accidental misconnections and ensure safe operation.

Overall, changeover switches provide essential functionality for maintaining electrical system reliability and enabling seamless power transfer when needed.

Contactors and Overload Relays are vital components in electrical systems, ensuring equipment protection and safe operation. Contactors act as electromagnetic switches, directing electrical power flow to loads like motors or lighting systems. Comprising a coil and contacts, they engage when a control signal energizes the coil, allowing current to flow. When the signal ceases, contacts open, cutting off the power supply. Contactors are built for high currents and voltages, ideal for heavy-duty tasks. Many feature auxiliary contacts for signaling, control, or interlocking, and some offer added safety elements like overload protection or surge suppression.

Overload relays, conversely, safeguard equipment by detecting and preventing excessive current flow, common in motors or transformers. They defend against overcurrent conditions that can harm or disrupt equipment. An overload relay consists of a current sensor, contacts, and a trip mechanism. If the actual current surpasses a predefined threshold, the trip mechanism activates, opening contacts and disconnecting power to the equipment. This prevents overheating and potential damage due to excessive current, guarding against motor overload, phase loss, and mechanical failures. Overload relays often have customizable settings, adapting to equipment-specific needs.

Contactors and overload relays collaborate in electrical systems, efficiently managing power distribution and safeguarding equipment from overcurrent issues. Their presence is essential for the secure and effective operation of diverse electrical applications.

Power factor capacitor and reactor are electrical devices used to manage and improve the power factor of electrical systems.

A power factor capacitor is designed to correct a low power factor, which is caused by inductive loads in the electrical system. Inductive loads, such as motors and transformers, draw reactive power from the power supply, resulting in a lagging power factor. The power factor capacitor is connected in parallel to the load and helps to offset the reactive power, bringing the power factor closer to unity (a power factor of 1). This not only helps improve the overall efficiency of the electrical system but also reduces energy consumption and prevents penalties from utility companies.

On the other hand, a power factor reactor is used to correct a high-power factor, which occurs in systems with capacitive loads. Capacitive loads, such as capacitors used in power factor correction devices, can cause excessive leading power factor.
