REF615C_E is a motor protection device produced by ABB, mainly used for feeder protection in distribution networks. The following is its detailed information:
Functional Features
Rich protection functions: It has directional or non directional overcurrent and ground fault protection, supports overvoltage, low voltage, zero sequence voltage protection, thermal overload protection, sensitive grounding protection, and quick break grounding protection (including intermittent grounding protection). Optional accessories can also be installed to directly integrate three arc protection channels, achieving arc detection and rapid protection for switchgear circuit breakers, cables, and busbar chambers.
Flexible reclosing function: It integrates multiple rounds of reclosing function with flexible configuration, which can achieve acceleration before and after reclosing and manual closing acceleration.
Diverse control functions: Supports local and remote control functions, and users can perform opening and closing operations on the circuit breaker through the control buttons on the device panel or the SCADA system in the background.
Strong communication capability: Supports substation IEC61850 communication standard, parallel redundancy protocol (PRP), and high availability seamless redundancy protocol (HSR), among which IEC61850 communication standard includes IEC61850-9-2LE. The SPA-ZC302 protocol adapter supports the Profibus DPV1 protocol, which facilitates communication and data exchange with other devices.
Application field: Known for its flexible configuration and wide applicability, it can serve as the main protection for overhead lines and feeders in distribution networks, as well as backup protection for equipment such as transformers. It is mainly used in the power industry such as substations and power plants, as well as industrial users such as cement, metallurgy, petrochemicals, automobiles, semiconductors, papermaking, tobacco, etc. It can also be used in municipal, airport, port, real estate and other industries.

The company has a leading advantage in discontinuing control system components. We have a large inventory and surplus of control system components, as well as some hardware for the discontinued control system. We have also released many new hardware and products to support your existing control system or apply new control technologies. The discontinued “DCS system spare parts, PLC module spare parts,” complete machine and accessories series have a strong advantage. As long as you need PLC products, we can help you find them. The company has a great price advantage.
