High-Performance Molded Case Circuit Breakers (MCCBs)

Ensure unparalleled safety and continuity for your electrical systems with our advanced range of Molded Case Circuit Breakers (MCCBs). Engineered for robust performance in commercial, industrial, and utility applications, our MCCBs provide critical protection against overloads, short circuits, and ground faults, safeguarding your equipment and personnel.

What is an MCCB?

A Molded Case Circuit Breaker (MCCB) is an electrical protection device designed to protect electrical circuits from excessive current, which can cause damage to equipment and pose fire risks. Unlike Miniature Circuit Breakers (MCBs), MCCBs are designed for higher current ratings and breaking capacities, often featuring adjustable trip settings for enhanced flexibility and selective coordination in complex power distribution systems. They are housed in a sturdy, molded insulating material to ensure durability and safety.

Key Features & Benefits:

• Superior Circuit Protection:
  • Overload Protection: Accurately detects and trips during sustained overcurrents, preventing overheating and damage to cables and equipment.
  • Short Circuit Protection: Reacts instantly to sudden, high fault currents, interrupting the circuit rapidly to minimize destructive energy and maintain system integrity.
  • Optional Ground Fault Protection: Integrated or add-on modules to detect dangerous ground faults, enhancing safety and preventing equipment damage.
• Wide Current Rating Range:
  • Available in ratings from 15A up to 1600A (and beyond), catering to a vast spectrum of applications from feeder circuits to main incomers.
• High Breaking Capacity (kA):
  • Designed to safely interrupt extremely high fault currents, with breaking capacities ranging typically from 10kA to 150kA at various voltages, ensuring reliable operation even in high-energy fault conditions.
• Flexible Trip Unit Options:
  • Thermal-Magnetic Trip Units: Combine thermal elements for overload protection and magnetic elements for short-circuit protection. Cost-effective and reliable for many applications.
  • Electronic Trip Units: Offer advanced, highly accurate, and adjustable protection characteristics.
    • Adjustable Long-Time (Overload): Fine-tune the current threshold and time delay for overload protection.
    • Adjustable Short-Time (Short Circuit Delay): Introduce intentional delays for selective coordination, ensuring only the affected circuit trips, minimizing downtime.
    • Adjustable Instantaneous (Short Circuit Pick-up): Set the immediate trip threshold for severe short circuits.
    • Ground Fault Protection: Integrated options for sensitive earth leakage detection.
    • Communication Capabilities: Modern electronic units can offer data logging, remote monitoring, and integration into building management systems (BMS) or SCADA systems.
• Robust Construction:
  • Housed in a durable, flame-retardant molded case, providing excellent insulation, mechanical strength, and protection against environmental factors.
• Modular & Expandable:
  • Designed for ease of installation, maintenance, and modification. Available in fixed, plug-in, and draw-out versions for enhanced flexibility and reduced downtime during maintenance or upgrades.
• Comprehensive Range of Accessories:
  • Auxiliary Contacts: For remote indication of breaker status (ON/OFF/TRIP).
  • Shunt Trips: For remote tripping of the breaker in emergency situations.
  • Undervoltage Releases (UVR): To trip the breaker when the supply voltage drops below a preset level.
  • Motor Operators: For remote or automatic switching operations.
  • Rotary Handles & Extended Shafts: For external panel mounting.
  • Alarm Switches: To signal a trip condition.
• Global Standard Compliance:
  • Manufactured and tested to meet international standards such as IEC 60947-2, UL 489, and CSA C22.2 No. 5, ensuring quality, safety, and compatibility worldwide.

Typical Applications:

Our MCCBs are indispensable in a wide array of demanding environments:

• Industrial Facilities: Factories, manufacturing plants, heavy machinery protection.
• Commercial Buildings: Office complexes, shopping malls, hospitals, data centers for main and sub-distribution panels.
