The Live CB132D Single Pole MCB is a specialized heavy-duty miniature circuit breaker engineered to provide reliable protection for demanding high-power single-phase industrial circuits with extremely high inrush currents. Rated at 32 Amps with a D-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. The D-curve characteristic (10-20x In) is specifically designed for applications with very high momentary startup currents, ensuring the breaker tolerates these surges while maintaining full protection against overloads and short circuits. With its robust construction and precision thermo-magnetic release, the CB132D ensures equipment protection and operational safety for the most demanding industrial applications.
High 10kA Breaking Capacity: Enhanced fault current interruption capability for installations with higher prospective short-circuit currents.
D-Curve Characteristic: Trips instantaneously at 10-20 times rated current (320A to 640A), specifically designed for applications with extremely high inrush currents.
High-Power 32A Protection with Extreme Surge Tolerance: Ideal for large single-phase industrial motors, heavy transformers, welding equipment, and heavy machinery with very high startup currents.
Single Pole Configuration: Protects one phase conductor for single-phase 230V heavy industrial circuits.
Industrial Heavy-Duty Focus: Prevents nuisance tripping where standard B/C curves would fail due to extreme inrush from large industrial equipment.
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 in demanding industrial environments.
Professional Installation: DIN-rail mounting with IP20 finger-safe terminals and 16mm² wiring capacity.

1. What type of industrial equipment requires a 32A D-Curve single pole breaker?
Large reciprocating compressors, punch presses, large industrial mixers, heavy-duty conveyor motors, and plasma cutters that draw startup surges exceeding 300A.
2. Can this breaker handle a 7.5HP single-phase motor?
Yes, a 7.5HP (5.5kW) single-phase motor drawing 32A running current with startup surges up to 250A is ideally protected by this 32A D-Curve breaker without nuisance tripping.
3. Why is 10kA breaking capacity critical for this 32A rating?
At 32A, installations are often closer to main distribution where fault currents can exceed 6kA. The 10kA rating ensures the breaker can safely interrupt higher short-circuit currents.
4. What is the maximum transformer kVA for this 32A D-Curve breaker?
Suitable for isolation transformers up to 7.5kVA and welding transformers up to 10kVA, handling the massive magnetizing inrush during energization without tripping.
5. Why is D-Curve preferred over C-Curve for large single-phase motors?
Large motors (5HP+) often have starting currents exceeding 10x running current. D-Curve's 10-20x range accommodates these extreme surges while C-Curve's 5-10x range would trip during startup.
