Palazzoli ATEX Surface-Mounted Two-Way Switch, 1P, 16A, 1xM20, IP66, Aluminium

The Palazzoli ATEX surface-mounted two-way switch is a high-performance electrical component engineered for secure operation in potentially explosive atmospheres. Constructed with a durable aluminium housing, this 1P 16A switch provides exceptional resistance to mechanical impact and environmental stressors. Its design ensures reliable switching functionality in demanding industrial settings where safety and compliance with international hazardous area standards are critical requirements.

Advantages

The primary benefit of this switch is its robust construction, which guarantees longevity even in harsh industrial conditions. The IP66 protection rating ensures that the internal components are fully shielded against dust ingress and powerful water jets, making it suitable for outdoor or wash-down environments. Furthermore, the inclusion of an M20 cable entry simplifies the installation process while maintaining the integrity of the explosion-proof enclosure.

Suitable for

• Industrial facilities with hazardous atmospheres
• Chemical and petrochemical processing plants
• Outdoor installations requiring high ingress protection
• Manufacturing environments with dust or moisture exposure

When it may not be suitable

This device is not intended for use in standard residential or office environments where ATEX-rated equipment is unnecessary. It is also not suitable for applications requiring higher current ratings than 16A or for systems that demand more than a single-pole switching configuration.

Key specifications

• Switch type: Two-way surface-mounted
• Current rating: 16A
• Poles: 1P
• Protection rating: IP66
• Material: Aluminium
• Cable entry: 1xM20

How to use

Installation should be performed by a qualified professional in accordance with local safety regulations for hazardous areas. The switch is designed for surface mounting using the provided fixing points. Ensure that the cable gland used for the M20 entry is compatible with the cable diameter and maintains the IP66 rating of the unit. Once mounted, connect the electrical conductors to the internal terminals, ensuring all connections are secure and the housing is properly sealed before energizing the circuit.

What to consider before purchase

• Verify that the hazardous area classification of your site matches the ATEX certification of the switch.
• Ensure the 16A current rating is sufficient for your specific load requirements.
• Check that the 1xM20 cable entry is compatible with your existing conduit or cable gland system.

Usage recommendations

Regularly inspect the housing for signs of physical damage and ensure that the cable entry point remains tightly sealed to maintain the IP66 protection level throughout the operational life of the device.
