LOVATO Electric presents switch disconnectors and changeovers GL series up to 1000A.
The offer of LOVATO Electric GL series switch disconnectors and changeover switches is getting wider with the introduction of a new construction size that covers applications up to 1000A. The new switch disconnectors and changeover switches can be actuated directly or used with a door interlocked handle and feature a wide range of accessories for all installation requirements.
The switching technology, designed for very fast actuation, allows the using of these devices for switching loads in category AC23A up to 1000A at 500V or 800A for higher voltages.
GL switch disconnectors up to 1000A feature an extremely compact body.
The UL98 versions, suitable for applications in the USA and Canada, are available from 100A to 800A and have a dimension that is the smallest currently available on the market.
The four-pole version can be made up directly by the client thanks to the supplementary fourth pole (available separately) which, like the neutral and earth terminals, can be installed on both sides of the switch with 2 screws included in the kit. The switch disconnectors can be mounted to a plate with 4 screws, without any restriction on positioning.
GLC changeover switches are supplied pre-assembled in the three-pole and four-pole configurations, and their electrical features make them compatible with any application, despite their small. They can be plate-mounted using 4 screws without any restriction on positioning.
For both types of products, the power contact position (open/close) can be seen via the transparent window on the front of the switch itself.
GL switch disconnectors and changeover switches can also be fitted with handles (available separately) for direct operation or door interlocked by installing an extension shaft. All versions have integrated padlock fittings and are available with the highest protection ratings on the market (IP66, IP69K and NEMA 4X).
The door interlock handles are available with shafts of various lengths; in order to prevent the inclination of very long shafts from causing interference with the doors, an accessory is available to support and perfectly guide the shaft into the handle while closing the door.
All door interlock handles are compliant with UL508A, which requires that trained personnel is able to inspect the panel when it is switched ON. To enable this, they are equipped with a mechanism to inhibit the mechanical interlock, which makes it possible to open the door even when the switch is in ON. This inhibition mechanism can only be enabled with a tool, to prevent involuntary operation.
To satisfy every installation requirement, along with the accessories above mentioned, a range of terminals auxiliary contacts, terminal covers and phase barriers are also available. The terminals are screw-mounting, while no tools are required to install the other accessories, since they securely snap on so that the installation is quick and easy.
The compactness and wideness make this series the ideal solution for switching applications, especially for installations in panels with limited space.
