Model Meaning

Normal Conditions of Use and Installation

● The surrounding air temperature should be -5℃~+40℃ (beyond the range can be used with reduced capacity), and the average value of 24h should not exceed +35℃;

● The altitude of the installation site does not exceed 2000 meters above sea level, and it can be used with reduced capacity if it exceeds 2000 meters;

● The relative humidity of the air at the installation site does not exceed 50% at a temperature of +40℃, and can be higher at lower temperatures, e.g. 90% at 20℃, and measures should be taken for occasional condensation due to temperature changes;

● Pollution class 3;

● The installation category of the main circuit of the circuit breaker is IV, and the installation category of the remaining auxiliary and control circuits is III;

● The circuit breaker shall be installed in a place where there is no danger of explosion, no conductive dust, no rain or snow, and no place where there is sufficient corrosion of metal and damage to insulation.

Main Technical Indicators

Intelligent Universal Circuit Breaker (Drawer Type) Mounting Dimensions

△ Steel cable interlocking of two flat or stacked circuit breakers

Note: The length of steel cable for steel cable interlocking is 2.5m, 1.5m steel cable can also be provided, but users need to specify when ordering.                              △Interlocking of two stacked circuit breakers with interlocking rods

Fixed and drawer type

Note: The distance between the upper and lower mounting plates is 0.6m~0.7m.

"Break" locking device

The "open gate" locking device can lock the break button of the circuit breaker in the pressed position, at this time, the circuit breaker will not be able to close.

Factory supplied locks and keys when fitted as an option to the user; three circuit breakers with three identical locks and two keys.
