Megger CSU600AT High Current Supply Unit

The Megger CSU600AT high-current supply unit has two main fields of application. The first is to conduct primary tests on protective relays. A primary test shows whether all parts of the protection system are functioning together properly within the specified time limits under operating conditions. The second field of application involves conducting current tests on low-voltage circuit breakers and overcurrent devices. It has a built-in timer and an analog ammeter that provide rough current settings quickly and easily. As a result, connection time has been reduced to the bare minimum. FEATURES Compact and rugged. Quick and easy to use. Broad application range. Excellent weight/performance ratio. Current Supply Units CSU600A/AT are used for: Performance and transformation-ratio testing of current transformers. Primary testing of relay-type cutouts. Testing circuit breakers. Commissioning of substation switchgear.
