Multi funcational Adjustable type RCBO circuit breaker with screen

GENERAL
STSF2-100(STRO7-40) series Multi function residual current circuit breaker with over current protection(RCBO)is suitable for AC 50/60Hz,
rated in a circuit with a voltage of 230V-400V and a rated current of 100A,when a person is electrocuted or the power grid leaks..
When the leakage,overvoltage,and undervoltage reach the set values,the residual current circuit breaker can quickly operate in a very short period of time quickly cut of the power supply.When the monitoring temperature of the residual current circuit breaker reaches the set value,the monitoring ground wire is not connected.

When connected,the product emits an alarm sound to protect the safety of personnel and electrical equipment,
and can avoid Prevent damage to equipment caused by overvoltage in the power grid.It has overload,short circuit,leakage,
overvoltage, undervoltage and overtemperature protection functions can also be used to intermittently turn on and off electrical
devices under normal circumstances lighting circuits,especially suitable for industrial and commercial lighting distribution systems.

The product has a small volume,compact structure,and better cost effectiveness than other similar products.It has a beautiful
appearance,high breaking capacity makesit a good choice for household power distribution.This product complies with
GB/T 16917.1 and IEC61009-1 standards and has obtained CE certification.

SURROUNDING AIR TEMPERATURE:
1.The ambient air temperature shall not be lower than -5ºC,not higher than+40ºC,and the daily average value shall
not exceed +35ºC .

2.Altitude:The altitude of the installation site shall not exceed 2000m.

3.Atmospheric conditions
The air is clean,and at a maximum temperature of+40ºC,the relative humidity of the air is not high More than 50%.Higher relative humidity is allowed at lower temperatures,such as at+20ºC,
The relative humidity should not exceed 90%.Due to occasional moderate condensation caused by temperature changes,
attention should be paid to taking appropriate measures.

4.Installation Category :DIN RAIL Installation.

5. Recommended selection principles:
5.1 General selection principles
a)The rated working voltage of RCBO ≥ the rated voltage of the line.
b) The rated current of RCBO is 1.1-1.25 times the load current calculated by the line.
c)The rated short-circuit breaking capacity of RCBO ≥ the maximum short-circuit
current that may appear in the line.
d)RCBO instantaneous release setting current ≤ 0.8 times the end of the line phase
-to-ground or phase-to-phase short circuit current.
e) Single-phase rated current of electric heaters, refrigerators and incandescent la-
mps at a given voltage and power In=P/U; three-phase rated current In=P/1.732U.
RCBO residual current is generally selected as 30mA, which is used as personal
contact protection.
