External Maintenance Bypass Switches for UPS Systems
If you are operating a UPS system, then having an External Maintenance Bypass Switch (EMBS) allows your critical power system more flexibility while maintenance is carried out on the UPS system. This allows you to safely keep the equipment online without interruption to the load.
Our range of maintenance bypass key-switches aims to offer key control to improve not only the safety aspect of bypass switching but ensuring only authorised personnel are able to use the switch when required thus maintaining the integrity of a sound UPS and maintenance system.We specialise in 1 to 4 pole, 2 to 4 position UPS bypass switches. Additionally we build rotary cam switches and reverse star delta switches, designed to customer specifications.
All of our products are manufactured to the highest standard using the superior quality materials from Germany. Ranging up to 1200 Amperes, our MBS units are the first and last word in electrical safety and control.
