Megger CSU600AT Current Supply Unit

Megger CSU600AT Current Supply Unit

The Megger CSU600AT high-current supply unit is designed for primary testing of protective relays and for current testing of low-voltage circuit breakers and overcurrent devices. A primary test shows whether all parts of the protection system work together correctly and within the specified time limits under operating conditions. Delivering up to 600 A, the CSU600AT includes a built-in timer and an analogue ammeter for quick current settings and accurate timed tests — so, unlike the CSU600A, no external timer or ammeter is required. It is well suited to relay testing and to current-transformer performance and turn-ratio tests.

Key features of the Megger CSU600AT

• Up to 600 A output – high-current primary injection for relay and breaker testing.
• Built-in timer & ammeter – integrated analogue ammeter and timer for fast setting and accurate timed tests (no external TM200 needed).
• Primary relay & breaker testing – primary tests of protective relays; current tests of LV circuit breakers and overcurrent devices.
• CT testing – suitable for current-transformer performance and turn-ratio tests.
• External ammeter output – 600/6 A output available, ±0.5% inaccuracy.
• Compact & portable – 115/230 V input, supplied in a transport case.
