JZB1 Series
Miniature Circuit Breaker
Introduction
JZB1 Series Miniature Circuit Breakers (MCB) are suitable for circuits with rated working voltage of 400VAC (50Hz) and rated current of 125A. JZB1 series circuit breakers are mainly used for lighting and power distribution in industrial, commercial, residential and other buildings.
How to order
Application environment
● 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;
● Altitude: ≤2000m;
● 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);
● Air pollution level: Level Ⅱ;
● Installation category: Class Ⅰ;
● Ingress Protection Ratings of Shell: IP20;
● Installation site: no significant shaking, impact and vibration, and the vertical inclination of the circuit breaker should not exceed 5°, the external magnetic field of the installation site should not exceed 5 times the geomagnetic field in any direction;
● DIN-rail specification: TH35-75 steel mounting DIN rail;
