2.Main Features

Multi-function protection:

REF601 CE446BB1NH has a variety of protection functions,including overcurrent protection,overload protection,short circuit protection,grounding protection and current differential protection,etc.,to ensure that the power system can operate stably in the face of various faults and abnormal conditions,and reduce potential damage.

Digital control:

The device uses digital technology with high precision and programmability.Users can customize it according to specific application needs to meet different control requirements.

Communication interface:

REF601 CE446BB1NH is equipped with a communication interface,which can communicate with other control systems,SCADA systems or remote monitoring systems to achieve remote monitoring and operation.This provides users with convenient remote management means and improves the flexibility and efficiency of the system.

Compact design and installation:

The device has a compact design and is easy to install and configure.As a hot-swappable module,it can be replaced or inserted without shutting down the system,thereby improving the reliability of the system and the convenience of maintenance.

Inrush current stabilization function:

REF601 CE446BB1NH also has an inrush current stabilization function,which allows the device to be used as the main protection of distribution transformers.

Rogowski current sensor:

As an alternative to conventional current transformers,REF601 CE446BB1NH has a Rogowski current sensor version,which helps to reduce the size of medium-voltage switchgear,improve performance and make it more standardized.

III.Main features

Apply to cables,overhead lines or transformer feeders in grounded,resistance-grounded or ungrounded systems.

Includes overcurrent,grounding,phase discontinuity and overload protection,as well as inrush current monitoring and other functions.

With pre-configured functions for circuit breaker control,reclosing and measurement,it is easy to debug quickly.

Input and output can be set through local HMI or communication interface.

Support Modbus and IEC 60870-5-103 communication protocols.

IV.Application areas

REF601 CE446BB1NH feeder protection and measurement and control device is suitable for utility and industrial power systems,especially the main protection of overhead lines and cable feeders in distribution and sub-distribution networks,and the main protection of distribution transformers.
