DZ47 Series
Miniature Circuit Breaker
Introduction
DZ47 Series Miniature Circuit Breakers are suitable for circuits with rated working voltage of 230/400VAC (50Hz/60Hz) and rated current of 63A. DZ47 series circuit breaker has the advantages of advanced structure, reliable performance, high breaking capacity, beautiful and compact appearance, no maintenance, and suitable for unexperienced personnel. The shell of DZ47 series is made of new plastic, so it has the advantages of good flame-retardant performance, arc resistance and impact resistance. The contact system of the DZ47 series adopts an electric repulsion mechanism, which has a significant current limiting effect and can greatly improve the breaking capacity of the circuit breaker. Various accessories can be assembled on the side of DZ47 series, such as shunt release, auxiliary contact, and alarm contact. The trip device of DZ47 series circuit breaker adopts solenoid type electromagnetic trip, the setting current is accurate and stable, but its protection characteristics have been set before leaving the factory, and you cannot adjust it during use. Multiple single-pole DZ47 series circuit breakers can be assembled into a multi-pole circuit breaker. DZ47 series circuit breakers are mainly used for lighting and power distribution in industrial, commercial, residential and other buildings. DZ47 series circuit breaker complies with the GB10963.1-2005 standard.

Electrical life: 4000 Times
Compliance with standards: IEC60898-1/GB10963.1
Application Environment
Altitude: ≤2000m
Air pollution level: Level Ⅱ
Installation category: Class Ⅲ
DIN-rail specification: TH35-75 steel mounting DIN rail
Wire specification: round copper wire with the terminal area not exceeding 25mm2 (1-63A) .
Ambient temperature: -5℃~+40℃, the average value of 24h does not exceed +35℃. If the circuit breaker works in an environment where the temperature is higher than +40°C or lower than -5°C, please contact us.
Relative humidity: monthly average ≤90% (the average temperature of the month is +25℃); relative humidity ≤50% (when the ambient temperature is +40℃). The relative humidity is related to the ambient temperature. The lower the ambient temperature, the higher the allowable relative humidity. For condensation caused by temperature changes, take appropriate protective measures (such as adding drainage holes).
Installation site: no significant shaking, impact and vibration, and the vertical inclination of the circuit breaker should not exceed 5°.
Derating factor: If the circuit breaker is installed in a closed protective enclosure and multiple units are installed close to each other, the derating factor (0.7~0.8) should be considered. A higher derating factor can be used for metal protective enclosures, and a lower derating factor can be used for plastic protective enclosures.
