11227 Domovoy VA 63 3P 40A C /SCHNEIDER/

Circuit breaker Domovoy ВА63 3P 40A type C 4.5kA /Schneider Electric/ The three-pole circuit breaker of the Domovoy (Домовой) series from Schneider Electric is designed to protect three-phase electrical circuits against overloads and short circuits. The model with a rated current of 40 amperes is a power device specially developed for use in the residential sector and civil construction. This series combines the proven reliability of Schneider Electric with an optimal cost, which makes it an ideal choice for protecting high-power household appliances and incoming distribution units in private houses. Technical parameters Brand: Schneider Electric Series: Domovoy (Домовой) Model: ВА63 Article number: 11227 Number of poles: 3 (3P) Rated current: 40 A Tripping curve: C (suitable for most types of load) Breaking capacity: 4.5 kA Rated voltage: 400 V AC Mounting type: DIN rail Width: 3 modules (54 mm) Degree of protection: IP20 Design features The circuit breaker is housed in a one-piece enclosure made of dielectric plastic resistant to high temperatures. The orange operating lever is the hallmark of the Domovoy series and makes the device easy to identify in the distribution board. The instantaneous trip mechanism guarantees simultaneous opening of all three phases when a fault is detected in any one of them. The terminal clamps hold the conductors firmly, preventing them from heating up. Clear marking of all technical parameters is provided on the front face. Advantages Specialisation in the residential sector: The device parameters are ideally balanced for the loads typical of flats and private houses. High power: The 40A rating in a three-phase network makes it possible to protect lines with a total power consumption of up to 25–26 kW. Safety of three-phase consumers: Synchronous disconnection of all phases prevents phase imbalance and failure of electric motors. Proven reliability: The Domovoy series is used by millions of users, confirming the stability of its tripping characteristics. Ease of installation: Standard DIN-rail mounting makes it possible to quickly install or replace the device in a switchboard. Scope of application In Almaty, Domovoy 3P 40A circuit breakers are most often used as incoming circuit breakers in cottages and private houses with a three-phase supply. They are also indispensable for protecting high-power electric heating boilers, large-capacity instantaneous water heaters and central air-conditioning systems. The type C characteristic allows the circuit breaker to cope successfully with the starting currents of compressors and pumps, ensuring reliable operation of the building services of the house without nuisance tripping.
