JZG1 Series
Miniature Disconnecting Switch
Introduction
JZG1 Series Miniature Disconnecting Switches (MDS) are suitable for circuits with rated working voltage of 400VAC (50Hz) and rated current of 125A. JZG1 series isolation switch is composed of a shell, an operating mechanism and a contact system. The operating mechanism and the contact system are rigidly connected. The contact system adopts a double-breakpoint direct-acting structure, and uses spring storage to realize rapid switching, which improves the reliability of work. JZG1 series isolators are mainly used for lighting and power distribution in industrial, commercial, residential and other buildings.

Rated making and breaking capacity: 3Ie/1.05Ue, COSΦ=0.65
Rated short-circuit making capacity Icm: 20kA(peak), COSΦ=0.95
Rated short-circuit withstand current Icw: 12Ie, 1s
Application Environment
Altitude: ≤2000m
Air pollution level: Level Ⅱ
Installation category: Class Ⅱ, Ⅲ
DIN-rail specification: TH35-75 steel mounting DIN rail
Wire specification: round copper wire with the terminal area not exceeding 25mm2
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°, the external magnetic field of the installation site should not exceed 5 times the geomagnetic field in any direction.
