24mm LA19 Series Push Button IP40 Industrial Control Circuit
Pushbutton Switch
Product Description:
The LA19 series pushbuttons are designed for industrial control
circuits operating at an alternating current (AC) frequency of 50
Hz or 60 Hz, with a rated working voltage up to 380 V AC, and a
direct current (DC) working voltage up to 220 V DC. These buttons
are used to remote control electromagnetic starters, contactors,
relays, and other electrical circuits.
Meet the standard: GB/T 14048.5.
Product Specification:
| Rated Insulation Voltage Ui(V) | 380V |

| Rated working voltage Ue(V) | 380V | 220V | 110V |
| Rated working current le(A) | AC-15 | 2.5 | 4.5 | - |
| DC-13 | - | 0.3 | 0.6 |
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 LA19 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 cutout dimensions for the mounting panel: Φ24.5 0+0.5 mm.
●Head protection rating: IP40.
●Short circuit protection: Type gG model 16.
