The Live CB132C Single Pole MCB is a high-capacity miniature circuit breaker engineered to provide reliable protection for very high-power single-phase electrical circuits in commercial, industrial, and large residential applications. Rated at 32 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 features an enhanced 10kA breaking capacity, making it suitable for installations with higher prospective short-circuit currents. It delivers precise protection against overloads and short circuits, making it the ideal choice for high-capacity circuits, large cookers, industrial power outlets, welding receptacles, and equipment where moderate inrush currents occur. With its robust construction and precision thermo-magnetic release, the CB132C ensures equipment protection and operational safety in demanding high-power applications.
High 10kA Breaking Capacity: Enhanced fault current interruption for installations with higher prospective short-circuit currents.
C-Curve Characteristic: Trips instantaneously at 5-10 times rated current (160A to 320A), ideal for very high-power circuits with moderate inductive loads.
High-Capacity 32A Protection: Perfect for large electric cookers, industrial power outlets, welding receptacles, and high-load commercial equipment.
Single Pole Configuration: Protects one phase conductor for single-phase 230V high-capacity circuits.
Industrial & Commercial Rating: 32A suits demanding applications in factories, workshops, large kitchens, and commercial facilities.
Precision Thermo-Magnetic Release: Thermal bimetal strip for overload protection and magnetic solenoid for short-circuit response.
Superior Electrical Isolation: 4000V impulse withstand rating and 500V insulation voltage.
Extended Operational Life: 8,000 electrical operations for long-term reliability.
Professional Installation: DIN-rail mounting with IP20 finger-safe terminals and 16mm² wiring capacity.

1. What are the main applications for the CB132C 32A 1P MCB?
Large electric cookers and ranges (7kW+), industrial single-phase power outlets, welding machine receptacles, large commercial catering equipment, and high-power heating systems.
2. What is the power capacity of this 32A single pole breaker?
Maximum resistive load: 7.36kW at 230V. Continuous load (80% rule): 5.89kW. Suitable for very high-power single-phase equipment and appliances.
3. Can this 32A breaker support a large commercial oven?
Yes, most large commercial ovens up to 7kW draw approximately 30A, making this 32A breaker ideally sized with appropriate safety margin for continuous operation.
4. Why is 10kA breaking capacity important for industrial power outlets?
Industrial environments often have high fault current potential due to proximity to transformers and main distribution. 10kA ensures safe interruption of these higher fault levels.
5. What cable size is recommended for 32A high-capacity circuits?
6mm² copper conductor minimum. 10mm² recommended for longer runs and industrial environments. Terminals accept up to 16mm² for flexibility.
