The Live CB210C Double Pole MCB is a versatile miniature circuit breaker designed to provide comprehensive protection for single-phase circuits requiring simultaneous switching of both phase and neutral conductors while handling moderate inrush currents. Rated at 10 Amps with a C-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 C-curve characteristic (5-10x In) provides excellent protection for circuits with small inductive loads while accommodating the inrush currents typical of fluorescent lighting, small pumps, and light commercial equipment. With its robust construction and precision thermo-magnetic release, the CB210C ensures complete circuit isolation and equipment protection for applications requiring double pole switching with inductive load tolerance.

Key Features of Live CB210C 10A 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.

  • C-Curve Characteristic: Trips instantaneously at 5-10 times rated current (50A to 100A), specifically calibrated for circuits with small inductive loads and moderate inrush.

  • Versatile 10A Protection with Inductive Tolerance: Ideal for small pumps, fluorescent lighting circuits, ventilation fans, and light commercial equipment.

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

  • Inductive Load Capability: Handles moderate inrush currents from small motors and lighting ballasts without nuisance tripping.

  • 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 10A C-Curve double pole MCB?
Small circulating pumps (up to 1HP), fluorescent lighting circuits with magnetic ballasts, ventilation fans, small commercial refrigeration units, and light industrial control circuits requiring neutral switching.

2. Why choose C-Curve over B-Curve for 10A commercial lighting circuits?
C-Curve (5-10x In) tolerates the inrush from fluorescent tubes and LED drivers (50-100A surge) where B-Curve (3-5x In) would nuisance trip during startup, especially with multiple fittings.

3. Can this breaker protect a small 750W circulation pump?
Yes, it's ideal for small pumps up to 750W. The C-Curve handles the motor starting current (up to 50-60A surge) while providing excellent overload protection during running.

4. What is the advantage of double pole for commercial equipment?
Double pole provides complete isolation of both phase and neutral, essential for safe maintenance of commercial equipment and compliance with electrical regulations in many jurisdictions.

5. What cable size is recommended for 10A C-Curve double pole circuits?
1.5mm² copper conductor minimum. 2.5mm² recommended for mechanical robustness in commercial installations. Terminals accept up to 16mm². Both phase and neutral conductors must be same size.
