The Live CH1100C Single Pole MCB is a high-capacity miniature circuit breaker designed to provide reliable protection for very high-power single-phase electrical circuits in industrial and commercial applications. Rated at 100 Amps with a C-curve tripping characteristic, this 1-pole breaker safeguards the phase conductor on AC systems up to 230V at 50/60Hz frequency. It delivers precise protection against overloads and short circuits, making it the ideal choice for main distribution feeders, large industrial equipment, high-power commercial installations, and applications requiring higher current capacity than standard MCBs. With its robust construction and precision thermo-magnetic release, the CH1100C ensures equipment protection and operational safety for demanding high-power applications.
High-Capacity Single Pole Protection: Protects one phase conductor for very high-power single-phase 230V circuits up to 100A.
6kA Breaking Capacity: Reliable fault current interruption for standard industrial and commercial installations.
C-Curve Characteristic: Trips instantaneously at 5-10 times rated current (500A to 1000A), specifically calibrated for high-power circuits with significant inductive loads.
Very High-Capacity 100A Protection: Ideal for main distribution feeders, large industrial equipment, high-power commercial installations, and heavy-duty applications.
Wide Application Range: Suitable for industrial facilities, large commercial buildings, and main distribution applications requiring high-current protection.
Precision Thermo-Magnetic Release: Thermal bimetal strip for accurate overload protection and magnetic solenoid for instantaneous short-circuit response.
Superior Electrical Isolation: 4000V impulse withstand rating and 500V insulation voltage for protection against voltage transients.
Extended Operational Life: 8,000 electrical operations for long-term reliability.
Professional Installation: Standard 35mm DIN-rail mounting with IP20 finger-safe terminals.

1. What specific applications require a 100A single pole MCB with C-Curve?
Main distribution feeders for large commercial units, high-power industrial equipment, large welding machines, heavy-duty industrial heaters, and sub-main distribution boards requiring high current capacity.
2. What is the power capacity of this 100A single pole breaker?
Maximum resistive load: 23kW at 230V. Continuous load (80% rule): 18.4kW. Suitable for very high-power industrial and commercial applications.
3. Can this breaker be used as a main switch for a large commercial unit?
Yes, it's ideal as a main isolation switch for large commercial units, small industrial facilities, and high-power workshops requiring up to 23kW single-phase supply.
4. Why choose C-Curve for 100A high-power circuits?
C-Curve (5-10x In) handles moderate inrush from large transformers and motor loads while providing excellent protection for general high-power industrial applications.
5. What cable size is required for 100A circuits?
25mm² copper conductor minimum. 35mm² recommended for longer runs or higher ambient temperatures. Ensure terminals are rated for appropriate cable size.
