Low voltage switchgear products are vital elements for controlling, protecting, and distributing electrical power for systems of up to 1 kV. This range includes circuit breakers, distribution boards, motor control centers, and protection devices. They help systems remain operational and fault-free, enabling reliability.
What is low voltage switchgear ?
Low voltage switchgear is an electrical system that provides control, protection, and power distribution for circuits that work at voltage levels of 1 kV or less. Its functional units include circuit breakers, switches, fuses, and protection relays that control the flow of electrical energy to keep the system safe and operational. They also provide the detection of system faults, such as overloads and short circuits, and provide the capability to isolate and clear the affected areas quickly.
Low voltage switchgear is used in homes, offices, and industrial applications. Providing fault detection and safe isolation enhances the operational safety, and an effective power distribution system ensures safe energy use. Additionally, new features in these systems allow digital control and monitoring, which greatly increases the effectiveness and control.
