For years, electrical switching devices for explosion-hazardous areas have been a focus for Pepperl+Fuchs. Now, the portfolio with electrical explosion protection has been updated with a completely new range of switch disconnectors (DIS*) and safety switches (SAF*) in types of protection Ex e and Ex tb. These product lines ensure safe disconnection of machines and power supplies for cleaning, maintenance or repair.
The new switch disconnectors and safety switches handle 25 A or 40 A operating current and are suitable for operation in gas and dust explosion-hazardous areas of Zones 1, 2, 21, and 22. Due to a wide range of configuration options, they can be tailored to meet diverse switching requirements. For instance, all products of these ranges can be purchased with either 3, 4, or 6 pole main contacts as well as with various auxiliary contact configurations.
The switches feature a glass fiber reinforced polyester or stainless steel enclosure with IP rating and a wide temperature range for use in almost any automation application. A threefold padlockable rotary actuator protects the devices from unauthorized access. Furthermore, the enclosure cover of SAF* models can only be opened when the switch is in ‘ON’ position, ensuring conformity with IEC 62626-1.
“By extending our portfolio with Ex e disconnectors and safety switches, we further shape our profile as a one-stop-shop for electrical explosion protection equipment. Whether terminal and junction boxes, control units, control stations, or complex control and distribution panels: we offer one-stop shopping to our customers with a high-quality product portfolio —from individual components to enclosures that are cast at our own facilities,” comments Product Group Manager Rainer Nägle.
