Decentralised maintenance switch

Friday, 01 February, 2008 | Supplied by: Weidmuller Pty Ltd


The PowerBox Maintenance Switch with ‘on/off’ function and integrated power distribution is IP65 rated, making it suitable for installation in industrial applications.

Individual machines, plant components, motor feeders and drive sub-circuits can be isolated from their power supply by utilising the switch, allowing maintenance and service work to be performed safely. An additional T-output to distribute power is possible through a push-in connection of the contact block.

The switch means users no longer require a separate maintenance switch or junction box, thereby reducing wiring, with installation made even faster by using pre-fabricated plug-in connectors.

The switch accommodates up to three padlocks to protect as many as three service technicians or teams against the power supply being unintentionally turned on. It is also possible for a PLC to scan the position of the switch via a floating auxiliary contact at the M12 connection of the device.

The upper and lower parts of the switch can be mounted in different locations at the same time. The lower part with integrated contact block can be installed on site, while the upper part can be assembled and terminated in the workshop. Both parts can then be snapped together on site and screwed tight, considerably reducing on-site mounting times and costs.
