The Live CB206C 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 while handling moderate inrush currents. Rated at 6 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 control transformers and small motors. With its robust construction and precision thermo-magnetic release, the CB206C ensures complete circuit isolation and equipment protection for applications requiring double pole switching with inductive load tolerance.
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 (30A to 60A), specifically calibrated for circuits with small inductive loads and moderate inrush.
Precision 6A Protection with Inductive Tolerance: Ideal for small control transformers, solenoid valves, small motors, and lighting with electronic ballasts.
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 control equipment 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.

1. What specific applications require a 6A C-Curve double pole MCB?
Small control transformers (up to 500VA), solenoid valve circuits, small circulating pump motors, lighting circuits with electronic ballasts, and control panels requiring neutral switching with inductive loads.
2. Why choose C-Curve over B-Curve for 6A double pole circuits?
C-Curve (5-10x In) tolerates the moderate inrush from control transformers and small motors (30-60A surge) where B-Curve (3-5x In) would nuisance trip during startup.
3. Can this breaker protect a small 500VA control transformer?
Yes, it's ideal for control transformers up to 500VA. The C-Curve handles the magnetizing inrush during transformer energization while providing excellent overload protection.
4. What is the advantage of double pole for control circuits?
Double pole provides complete isolation of both phase and neutral, essential for safe maintenance of control panels and compliance with machinery safety standards (IEC 60204).
5. What cable size is recommended for 6A C-Curve double pole circuits?
1.5mm² copper conductor minimum. 2.5mm² recommended for mechanical robustness in control panels. Terminals accept up to 16mm². Both phase and neutral conductors must be same size.
