UR8NH GE Multilin 8CT High Density CT/VT Module

The UR8NH is a single-slot plug-in high-density CT/VT analog input module built for GE Multilin UR universal protection relays. It features 8 CT input channels and supports additional VT inputs, enabling sampling of multiple current and voltage signals for multi-feeder, busbar and complex power protection schemes. This module incorporates enhanced per-channel diagnostics to detect open CT, broken wiring and abnormal signal conditions. Galvanic isolation protects the relay backplane from voltage transients and electromagnetic interference. It adopts automatic CT shorting during removal to eliminate the risk of dangerous open CT secondary voltage during maintenance. The module is auto-recognized by UR relay firmware for simple drop-in replacement and retrofit. We supply surplus original and fully tested refurbished UR8NH modules with worldwide shipping and pre-shipment functional testing.

H2: FAQ

Q: What is UR8NH?

A: UR8NH is GE Multilin UR series high-density 8CT CT/VT analog input module, collecting multi-circuit current and voltage signals for multi-feeder and busbar protection applications.

Q: What is the difference between UR8NH, UR8FV, UR8GH and UR8LH?

A: UR8NH = high density 8CT for multi-feeder / busbar protection; UR8FV = standard 3CT+1GCT feeder module; UR8GH = sensitive ground fault optimized for generator protection; UR8LH = 4CT/4VT dedicated for transmission line protection.

Q: Does UR8NH prevent open CT hazards?

A: Yes. UR8NH automatically shorts CT circuits when pulled out of chassis to avoid dangerous open CT secondary voltage during maintenance. It also has built-in per-channel diagnostics for open CT detection.

Q: Are your UR8NH modules new?

A: We offer surplus original and fully tested refurbished UR8NH modules. Contact us to confirm available condition and stock.

Q: What about warranty?

A: Warranty is available for tested modules; the warranty period depends on product condition.
