Ex main switches

High-quality main switches can be used in explosion hazard zones 1, 2, 21 and 22. They meet all stringent standards (found in the ATEX Directive (94/9/EC)). They can be used as main power switches for frequency converters. They also work well with engines and many other electrical devices. The proposed main switches are equipped with a lock in the "off" position. This reduces the risk of accidental start-up.

The full switching capacity of AC-3 applies to all main switches up to 180 A. They have been designed in accordance with the PN-EN 60947-3 standard. Their advantage is not only easily accessible connections, but also a practical design that facilitates installation. The housing is made of polyamide or polyester reinforced with glass fiber. They are not only durable, but also resistant to environmental conditions. Another advantage is the high degree of protection IP 66. Switches in metal casings (above 180 A) are also available.
