- Continuously supervises buswires in high-impedance protection schemes.
- Detects open-circuited buswires and open-circuited main current transformers.
- Provides integral buswire shorting, alarm contacts and a mechanical operation flag.
MVTP31V1CB0751E is an Alstom buswire voltage supervision relay designed for its documented industrial platform or application.
The supplied AREVA T&D Automation nameplate confirms Cortec Code MVTP31V1CB0751E. The current GE Vernova MVTP brochure identifies MVTP31 as the three-phase buswire-supervision version and documents its supervision, timing and contact functions.
Before installation or replacement, verify the complete catalog number, compatible hardware, wiring, configuration and installed-system requirements.
Availability, condition, price, and shipping time for MVTP31V1CB0751E are confirmed during quotation.

- Continuously monitors the AC voltage input against the selected threshold.
- Actuates the output relay when the monitored voltage exceeds the preset level.
- Indicates relay operation with a hand-resettable mechanical flag.
- Offers a fixed three-second or ten-second operating delay selected when ordering.
- Specifies a 150 ms contact disengaging time.
- Specifies a drop-off/pick-up ratio above 85% after the three-second delay and above 98% before it.
- Uses normally open buswire shorting contacts.
- Allows alarm contacts to be specified as 2 make, 1 make/1 break or 2 break.
- Rates the hand-reset contacts to carry 150 A rms for 0.5 seconds.
- Buswire supervision in high-impedance busbar protection schemes
