GLC changeover switch disconnectors



This new range of products covers applications from 160A to 315A (AC31B), can be actuated directly or used as door interlocks and feature a wide range of accessories for all installation requirements.

Their power contact control technology, designed for very fast actuation, also enables them to be used in category AC33B without derating up to 250A.

GLC changeover switch disconnectors are supplied pre-assembled in the three-pole and four-pole configurations and their electrical specifications make them compatible with any application, despite their small size (the four-pole version is just 221mm wide). They can be plate-mounted using screws without any restriction on positioning.

The power contact open/closed setting can be seen via the transparent window on the front of the unit itself.

They can also be fitted with handles (available separately) for direct operation or as door interlocks by installing an extension shaft. All versions have integrated padlock fittings and are available with the highest protection ratings on the market (IP66 and NEMA 4X). The door interlock handles are available with shaft extensions of various lengths and, to prevent very long shafts interfering with the door itself, an accessory is available which guides the shaft into the handle when the door is closed.

All door interlock handles are compliant with UL508A, which requires that trained staff can inspect the enclosure when it is live. To enable this, they are equipped with a mechanism to inhibit the mechanical interlock, which makes doors opening possible even when the switch is in ON position. This inhibition mechanism can only be enabled with a tool, to prevent involuntary operation.

To satisfy every installation requirement, further to the above accessories, a range of auxiliary contacts, terminal covers, phase barriers, terminal lugs and bridge bars is available.
No tools are required to install these accessories, since they snap on securely so that installation is quick and easy, and access to panel for maintenance is guaranteed.

The GLC range offer a modular solution to rationalise stocks, thanks to their standardised accessories.
