Luminaire Push Button

The UH-UP operators are normally used in the chemical and petrochemical plants, off-shore platforms, refineries and any other industry where hazardous atmospheres (gas and combustible dust) are potentially present. The UH-UP operators range has been designed to meet the main requirements of power distribution, monitoring and signaling, and other electrical functions inside the hazardous area of the plant.

The WH - WP - WA series are normally installed on CSE enclosures series used for the following main applications: • control station and instrument housing

• motor starter unit

• instrument housing

• lighting control panel and fitted with other electrical and/or electronic equipment as per our client specific requirements.

The material used to manufacture the UH-UP operators and WA instruments have been studied to grant the maximum protection against the highly corrosive agents present in these industries:

• the external components (handle, push-button, diffuser, ect.) are made of high-quality antistatic and UV-protected polymers and provided with EPDM sealing to mantain the IP66 level of protection of whole control station;

• the internal Ex d components are made of high quality thermoplastic and are available for standard installation on cover or, as option, on a dedicated mounting rail;

• the larger handles are padlockable in different positions (upon request)

• the LED units for pilot light and luminaire push button are available with two range of voltage as indicated in the ordering table;

• the rated current of Ex switch module is up to 16 Amp. and its mechanical life is 1,000,000 times;

• the high brightness and the electrical life of LED units are granted for a minimum of 100,000 hours;

• the diffuser of pilot lights and luminaire push button units have a special design to grant a high visibility degree in any situation

• the external components are fixed directly on cover with a Ø 30 mm. hubs and a directional anchor point depending by type of installation requested.
