PowerGuard 0800

PowerGuard 0800 is a system to provide safe maintenance areas for servicing overhead cranes and other mobile equipment without having to shut down the whole runway. This specially engineered switch array is ideal for our 0812 or 0813 conductor rail programs.

The system is available up to 1250 A and voltages up to 690 V. Target applications are overhead crane systems and other similar applications.

Use PowerGuard 0800 when... 

• you need an individual isolation of single mobile consumers on a shared conductor rail system
• you need explicit workers safety during maintenance 
• you want to avoid an overall shut-down of the runway during maintenace
• you want to be in line with today‘s requirements for the general safety of electrical equipment
• Easy-to-integrate maintenance system out of the box

Key features: 

• Robust and well-tested industrial design.
• Easy to implement for retrofits as well as for new installations.
• True isolation of Maintenance Zone via Buffer Zone, also if units are powered via arrays of multiple current collectors.
• Simple standard component selection.
• Easy use via simple switch operation.
• Two switches in one housing to separately disconnect the power from the Buffer Zone and Maintenance Zone.
• Interlocking concept with key switches to ensure a correct switching sequence.
• Switches with padlocks provision to lock the switch against reclosure.
• Integrated Earthing / Grounding Function of the Maintenance Zone.
• Maintenance Zone can be re-energized (e.g. for testing purpose) while the Buffer Zone remains OFF.
• Optional phase indication lights for remote visual identification of the conductor rail system and correct switching sequence.
• Designed and manufactured to CE standards.
