Miniature Circuit Breakers (MCB)
Miniature Circuit Breakers (MCBs): Reliable Protection for Low Voltage Systems
At United Force Trading Company, a trusted Schneider Retail Partner, Miniature Circuit Breakers (MCBs) are a cornerstone of our LV power component portfolio. Designed to safeguard electrical circuits from overloads and short circuits, MCBs are essential for ensuring safety, preventing equipment damage, and maintaining uninterrupted power in residential, commercial, and industrial applications.
What is an MCB?
An MCB is an automatically operated electromechanical device that interrupts abnormal current flow (overload or short circuit) in a circuit. Unlike traditional fuses, MCBs can be manually reset after tripping, offering reusable protection and eliminating the need for replacements.
Key Features of Schneider MCBs:
Compact Design: Space-saving and ideal for modern electrical panels.
Precision Protection: Tailored tripping mechanisms to match circuit requirements.
Durability: High mechanical and electrical endurance for long-term reliability.
Easy Installation: Modular design with tool-free DIN rail mounting.
Types of MCBs
Schneider MCBs are categorized based on their trip curves, which define their response to inrush currents and fault conditions:
Type B (Tripping at 3-5x Rated Current):
Use: Residential and light commercial applications (lighting, sockets).
Ideal For: Circuits with low inrush currents (e.g., household appliances).
Type C (Tripping at 5-10x Rated Current):
Use: Commercial/industrial settings with moderate inrush currents.
Ideal For: Motors, transformers, and fluorescent lighting systems.
Type D (Tripping at 10-20x Rated Current):
Use: Heavy industrial applications with high inrush currents.
Ideal For: Welding equipment, large motors, and X-ray machines.
Application Of MCBs?
MCBs are versatile and widely used in:
Residential: Protecting wiring, lighting, and appliances in homes.
Commercial Buildings: Safeguarding office equipment, HVAC systems, and data centers.
Industrial: Securing machinery, control panels, and production lines.
Renewable Energy Systems: Ensuring safety in solar PV installations and battery storage.
