Introduction

The ABB RXSF1 is a signal flag relay designed for electrical protection and control systems, providing reliable visual indication of system status and fault events. It is used as an operating indicator within protection schemes to clearly display relay operations through a mechanical red flag system.

Designed for DC voltage environments (110–125 V DC), the RXSF1 ensures dependable status signaling in substations, switchgear panels, and industrial power systems. It supports both voltage-operated and current-operated configurations, making it suitable for a wide range of protection and monitoring applications.

The relay plays an important role in system diagnostics by converting electrical events into clear visual indicators, helping operators quickly identify and respond to abnormal conditions.

Function

The primary function of the ABB RXSF1 is to provide clear and reliable visual indication of electrical protection system events.

It monitors DC control signals and activates a mechanical red flag when a relay operation or fault condition occurs. In current-operated configurations, it also verifies circuit breaker trip coil current flow, confirming successful breaker operation.

The relay enhances system safety by translating electrical signals into visible status information, allowing operators to quickly assess system conditions and take corrective action.

Typical applications include:

Power transmission and distribution substations
Circuit breaker monitoring systems
Electrical protection relay schemes
Industrial switchgear systems
Substation automation systems
Power generation facilities
Industrial electrical control panels
