Miniature circuit breakers

Hager Miniature Circuit Breakers (MCBs) are compact, automatic switching devices designed to protect electrical circuits from damage caused by overloads and short circuits. When an abnormal current is detected, the MCB interrupts the flow to prevent hazards such as fire, equipment failure, or wiring damage. Hager MCBs are engineered for high reliability, easy installation, and long-term performance in residential, commercial, and industrial environments.

Types of Hager MCB

Hager MCBs are categorized by their tripping characteristics, which define how quickly they respond to overcurrent conditions:

• Type B: Trips between 3 to 5 times the rated current; suitable for lighting and general domestic use.
• Type C: Trips between 5 to 10 times the rated current; ideal for commercial and mixed inductive/resistive loads like small motors and appliances.
• Type D: Trips between 10 to 20 times the rated current; designed for heavy inductive loads such as industrial motors, transformers, and large machinery.

These MCBs are available in various current ratings ranging from 0.5A to 63A, depending on the application needs.

Key Features of Hager MCB

• High Breaking Capacity: Rated at 6kA or 10kA, ensuring the breaker can safely interrupt high fault currents without damage.
• Compliance with Standards: Built in accordance with IEC 60898-1 for global safety and performance assurance.
• Bi-Connect Terminals: Allow simultaneous connection of both cable and busbar, reducing installation time and improving flexibility.
• Positive Contact Indication: Provides a clear visual cue that ensures the device is truly off before maintenance.
• Compact Modular Design: Fits easily into standard distribution boards, offering a space-saving solution without compromising performance.
• Long Mechanical Life: Designed for durability, with a high number of switching cycles for extended usage.
