ABB Relay Retrofit Program for SPACOM to REX615 Product Guide

ABB has released a product guide for the replacement of SPACOM series protection relays with REX615 relays (4TLB000502 B version), which provides a switchgear lifecycle extension solution for power systems. Through the use of REX615 integrated relays and specialized retrofit accessories, rapid replacement can be achieved, supporting more than 20 SPACOM models and significantly reducing wiring and downtime. At the same time, engineering configuration, installation tools, ordering codes, and training services are provided, fully compatible with multiple protocols such as IEC 61850, meeting the needs of modern substation automation.

Key questions and answers

Question: What is the biggest engineering advantage of this renovation plan?

Answer: The core advantage is equipped with specialized modified connectors, marked according to the original SPACOM terminal number, which can be directly plugged in without the need for redrawing drawings and extensive wiring changes. At the same time, it is matched with cutting tools and brackets to minimize power outages and installation time.

Question: What are the core technological improvements of REX615 compared to the replaced SPACOM relay?

Answer: REX615 belongs to the new generation Relion series, with a compact and withdrawable design that supports modern substation protocols such as IEC 61850. It can expand protection, control, and status monitoring functions, fully adapting to the automation needs of digital substations.

Question: What are the two modes for ordering and configuring renovation plans, and what scenarios are they suitable for?

Answer: It is divided into pre configured (C suffix) and non pre configured (N suffix); Pre configured with factory matched original SPACOM parameters, ready to use upon power up, suitable for quick replacement; No pre configuration is suitable for sites that require custom functions, and can be flexibly configured through PCM600.
