The Live CB220B Double Pole MCB is a high-capacity miniature circuit breaker designed to provide comprehensive protection for high-power single-phase circuits requiring simultaneous switching of both phase and neutral conductors. Rated at 20 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 high prospective short-circuit currents. The B-curve characteristic (3-5x In) provides fast response to faults while accommodating the minimal inrush currents typical of high-power resistive loads. With its robust construction and precision thermo-magnetic release, the CB220B ensures complete circuit isolation and equipment protection for residential, commercial, and industrial applications requiring double pole switching for higher current circuits.
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 (60A to 100A), specifically calibrated for high-power resistive loads with minimal inrush.
High-Capacity 20A Protection: Ideal for large water heaters (4.5kW), commercial ovens, high-power lighting, and dedicated appliance circuits.
Complete Isolation: Neutral pole disconnects simultaneously with phase, preventing floating neutral conditions and ensuring safety during maintenance.
Commercial & Industrial Rating: 20A suits demanding applications in restaurants, hotels, workshops, and commercial spaces.
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 20A double pole MCB with B-Curve?
Large instant water heaters (4.5kW), commercial ovens and cooktops, high-power lighting circuits in warehouses, dedicated workshop machinery circuits, and EV charging points requiring neutral switching.
2. Can this 20A double pole breaker support a 4.5kW instant water heater?
Yes, a 4.5kW water heater at 230V draws approximately 19.6A, making this 20A breaker perfectly sized with minimal headroom. Double pole ensures complete isolation for bathroom safety.
3. What is the power capacity of this 20A double pole breaker?
Maximum resistive load: 4.6kW at 230V. Continuous load (80% rule): 3.68kW. Perfect for high-power commercial kitchen equipment and dedicated appliance circuits.
4. Why choose double pole for commercial kitchen equipment?
Double pole provides complete isolation of both phase and neutral, essential for safety in commercial kitchens where equipment may be cleaned or serviced frequently and where water exposure is common.
5. What cable size is recommended for 20A double pole circuits?
2.5mm² copper conductor minimum. 4mm² recommended for longer runs or high ambient temperatures. Terminals accept up to 16mm². Both phase and neutral conductors must be same size.
