The Live CB206B Double Pole MCB is a precision-engineered miniature circuit breaker designed to provide comprehensive protection for single-phase circuits requiring simultaneous switching of both phase and neutral conductors. Rated at 6 Amps with a B-curve tripping characteristic, this 2-pole breaker safeguards both the phase and neutral conductors on AC systems up to 230/400V at 50/60Hz frequency. It features a powerful 10kA breaking capacity, making it suitable for installations with higher prospective short-circuit currents. The B-curve characteristic (3-5x In) provides fast response to faults while accommodating minimal inrush currents typical of sensitive circuits. With its robust construction and precision thermo-magnetic release, the CB206B ensures complete circuit isolation and equipment protection for residential, commercial, and industrial applications requiring double pole switching.

Key Features of Live CB206B 6A 2P MCB

  • Complete Double Pole Protection: Simultaneously protects and switches both phase and neutral conductors, ensuring complete circuit isolation during fault conditions and maintenance.

  • High 10kA Breaking Capacity: Powerful fault current interruption for installations with high prospective short-circuit currents up to 10,000 amps.

  • B-Curve Characteristic: Trips instantaneously at 3-5 times rated current (18A to 30A), specifically calibrated for sensitive circuits with minimal inrush.

  • Precision 6A Protection: Ideal for lighting circuits, control systems, PLC power supplies, and sensitive electronic equipment.

  • Complete Isolation: Neutral pole disconnects simultaneously with phase, preventing floating neutral conditions and ensuring safety during maintenance.

  • Wide Application Range: Suitable for residential, commercial, and light industrial installations requiring double pole protection.

  • Precision Thermo-Magnetic Release: Thermal bimetal strip for accurate overload protection and magnetic solenoid for instantaneous short-circuit response on both poles.

  • 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 and 16mm² wiring capacity.

Frequently Asked Questions (FAQs)

1. What specific applications require a 6A double pole MCB with B-Curve?
Lighting circuits in bathrooms and outdoor areas (safety isolation), control circuit transformers, PLC power supplies, small appliance circuits requiring neutral switching, and circuits where complete isolation is mandated by regulations.

2. Why choose double pole over single pole for 6A lighting circuits?
Double pole provides complete isolation of both phase and neutral, essential for safety in wet locations (bathrooms, kitchens), for equipment requiring total disconnection, and compliance with local electrical codes.

3. What is the power capacity of this 6A double pole breaker?
Maximum resistive load: 1.38kW at 230V. Continuous load (80% rule): 1.1kW. Suitable for approximately 30-40 LED downlights (30W each) or control transformers up to 1kVA.

4. Can this breaker be used for lighting circuits in bathrooms?
Yes, it's ideal for bathroom lighting circuits where double pole isolation is often required by electrical regulations to ensure both phase and neutral are disconnected for safety in wet environments.

5. What cable size is recommended for 6A double pole circuits?
1.5mm² copper conductor minimum. 2.5mm² recommended for mechanical robustness. Terminals accept up to 16mm² for installation flexibility. Both phase and neutral conductors must be same size.
