Descripción

Product Description

The REF601CE446BB1 feeder protection relay from ABB belongs to the Relion 600 family, engineered for dependable protection, measurement, and control of medium-voltage distribution feeders. Designed with a compact footprint and DIN-rail mounting, this relay is well suited for space-constrained switchgear panels in substations and industrial power systems.

Built on ABB’s proven protection platform, the REF601CE446BB1 combines essential feeder protection algorithms with advanced monitoring and communication capabilities. It supports digital substation architectures and integrates smoothly into modern automation environments through IEC 61850 and conventional serial protocols.

Frequently Asked Questions

Q: Is the REF601CE446BB1 suitable for IEC 61850 substations?
A: Yes. The relay natively supports IEC 61850, enabling seamless integration with modern digital substations and station-level systems.

Q: Can the same relay be used for both 1 A and 5 A CT inputs?
A: Yes. The rated current input is configurable via settings, allowing use with either 1 A or 5 A current transformers.

Q: Is this model suitable for retrofit projects?
A: Absolutely. Its compact DIN-rail design and wide auxiliary voltage range make it ideal for replacing older feeder protection relays.
