Product Description:
The NP4 series buttons are suitable for using in circuit control
systems operating at an alternating current (AC) frequency of 50 Hz
or 60 Hz, with a voltage up to 380 V AC, and a direct current (DC)
working voltage up to 220 V DC. These buttons are primarily used to
control electromechanical starters, contactors, relays, and other
electrical circuits.Button with integrated indicator light is also

Operating Conditions and Environmental Suitability:
●Ambient temperature is -5℃~+40°C, the average temperature during
24 hours couldn't exceed +35°C.
●Altitude: ≤2000m.
●Atmosphere condition: Relative humidity of the atmosphere couldn't
exceed 50% when the highest temperature is +40°C; much higher
relative humidity is allowable under the condition of lower
temperature, for example, when the temperature reaches +20°C, the
relative humidity is up to 90%, taking into account the
condensation that may occur on the product surfaces due to
temperature changes.
●Pollution grade: 3.
●Installation category: II.
●The NP4 series pushbutton should be installed in an environment
without significant shaking, impact, vibration, and without
exposure to rain or snow.
●It should be installed in an environment without the risk of
explosion and where the medium does not contain gases that could
corrode metals or destroy insulation, nor excessive dust.
●The buttons should be mounted into a round hole in a control
panel. The round hole can include a slot to prevent rotation. If a
slot is provided, its standard position is at the top (12 o'clock
position).
