LOW VOLTAGE SWITCHGEARS
Product Overview
Low voltage (LV) switchgear is a centralized assembly of electrical components that protect, control, and isolate electrical circuits operating at voltages up to 1,000 volts AC or 1,500 volts DC. It is a critical part of power distribution systems in industrial, commercial, and residential facilities.
Air Circuit Breaker (ACB)
An Air Circuit Breaker (ACB) is a high-capacity electrical safety device that automatically interrupts high currents in low-voltage systems (e.g., below 450V, 800A-10kA) during faults like overloads or short circuits, using a blast of compressed air to extinguish the electrical arc and protect equipment. ACBs are vital in main distribution panels for factories, substations, and large buildings, providing reliable power distribution and protection without oil, which enhances safety.
MCCB (Molded Case Circuit Breaker)
An MCCB (Molded Case Circuit Breaker) is an electrical protection device that safeguards circuits from overloads and short circuits, designed for higher currents than MCBs and suitable for commercial/industrial use, offering features like adjustable trip settings for precise protection and circuit isolation in its durable case.
Miniature Circuit Breaker (MCB)
A Miniature Circuit Breaker (MCB) is an electromechanical safety device used to protect electrical circuits from damage caused by overcurrent. Unlike a fuse, which melts and must be replaced, an MCB acts as a resettable switch that automatically trips to cut off power during a fault.
