Air Circuit Breaker (ACB) and Molded Case Circuit Breaker (MCCB) are used to protect electrical systems from overloads, short circuits, and other electrical faults in industrial, commercial, and residential applications.
Air Circuit Breaker (ACB)
An ACB is typically used for high voltage and high current applications. It ensures protection by interrupting the circuit when a fault is detected.
Key Features of ACB:
- High Voltage Protection: Suitable for systems with voltage ratings up to 1,000 volts.
- Adjustable Trip Settings: Allows control over how quickly the breaker trips during a fault.
- Arc Quenching: Efficient arc extinguishing technology to prevent damage during fault interruption.
- Manual and Automatic Operation: Can operate both manually and automatically for versatility.
- Durability: Built for long operational life, even in high-duty cycles.
Applications:
- Industrial plants
- Power distribution systems
- Commercial buildings
- Large electrical panels
Molded Case Circuit Breaker (MCCB)
An MCCB is used for medium-voltage applications and is known for its compact size and affordability.
Key Features of MCCB:
- Medium Voltage Range: Typically used in systems up to 1,000 amps and 690 volts.
- Thermal-Magnetic Protection: Provides both overload and short circuit protection using thermal and magnetic mechanisms.
- Compact Design: Ideal for applications with limited space.
- Adjustable Trip Settings: Customizable trip settings to suit different load protection requirements.
- Cost-Effective Solution: More affordable compared to ACB for medium-scale power protection.
Applications:
- Residential buildings
- Commercial buildings
- Small industries
- Distribution boards
