GEWISS improves rotary isolator switches
Posted by: electime 11th June 2018
GEWISS has launched a new and improved range of its popular rotary isolators, offering a wider range of codes, and special features to create a buzz in the industry.
70 RT HP (High Performance) is a range of surface-mounted rotary isolators designed for use as main switches for applications that need to be isolated from a network. This range complements GEWISS IEC 309 High Performance range of plugs and sockets.
The devices are available with plastic or metal boxes, in versions from 16A to 160A. Reducing installation time and providing the ultimate solution in terms of safety and strength, the new range of isolators are available in both control and emergency versions with a variety of poles: 2P, 3P, 3P+N or 4P.
The range includes panel-mounted options, for front-panel or DIN rail (EN50022) assembly in 16 to 63A options, all of which can be equipped with auxiliary contacts. This means the range is extremely flexible as it can be installed in any of GEWISS’ enclosures and distribution boards.
These devices have been designed to reduce wiring time, simplifying installation, and offer maximum safety and durability, even in the most demanding conditions. The innovative protection level – up to IP69 against the ingress of dust and water jets, means the 70 RT HP isolators range meet the most demanding requirements, even heavy-duty ones.
70 RT HP is ideal for a wide variety of applications, including industrial kitchens, air conditioning systems, lifts, technical rooms, modular buildings and even for the most heavy-duty applications.
With a modern and ergonomic design, the range fits in perfectly with the entire Gewiss industrial system, and offers high impact resistance at IK08, UV protection, and protection against chemicals.
With protection of IP66/IP67/IP69 protecting the product from dust and liquid ingress, 70 RT HP switch isolators are ideal for demanding applications, thanks to their high level of mechanical resistance.
Fast and easy to install
The plastic front of 70 RT HP isolators can be closed with just four quarter-turn captive screws.
70 RT HP features ergonomically-designed switches that are hardwearing. The padlocking system, concealed within the switches, will take up to 3 padlocks and can be locked in both ON and OFF positions in the command versions (in the emergency version the switch can only be locked in the OFF position).
More technical features have been introduced to this range:
- Dual metric entry points top and bottom.
- External fixing points for surface-mounting.
- Plenty of internal space for cable wiring.
- Optional N/O N/C auxiliary contacts make them suitable for a wide variety of applications.
The metal box versions (IP66) are made from painted aluminium alloy. The devices are also available in ATEX versions up to 100A for explosive atmospheres.
The metal box is pre-equipped with 4 external brackets for surface-mounting, maintaining the original IP rating even after installation. The bottom of all versions up to 80A are pre-drilled, ready to take metric cable glands.
