ABB 1SDA038292R0001 Shunt Opening Release Overview

The ABB 1SDA038292R0001 is a shunt opening release designed as an electrical accessory for ABB SACE low voltage circuit breaker systems. It is used to provide remote opening control of compatible circuit breakers through an external electrical command signal. The device operates as a trip coil that activates the breaker opening mechanism when the specified control voltage is applied.

In modern industrial power distribution systems, remote circuit breaker control is an essential function for improving operational safety, automation capability, and emergency response performance. The ABB 1SDA038292R0001 allows operators and automation systems to disconnect electrical circuits remotely without requiring direct manual operation at the switchgear location.

This accessory is mainly associated with ABB Emax series air circuit breakers and is designed to integrate into the internal operating mechanism of the breaker. It expands the functionality of the protection system by adding controlled remote tripping capability. The product catalog identifies the device as a shunt opening release with a 220-240V AC/DC supply range for E1/6-T8 breaker applications. :contentReference[oaicite:1]{index=1}

Function of ABB 1SDA038292R0001

The primary function of the ABB 1SDA038292R0001 is to remotely trip a circuit breaker. When an external control voltage is applied to the release coil, the electromagnetic mechanism generates the force required to activate the breaker trip mechanism. The circuit breaker then moves from the closed position to the open position, interrupting current flow and protecting the electrical system.

This operation is different from automatic protection tripping caused by overload or short-circuit conditions. The shunt opening release provides an externally controlled opening command, allowing integration with emergency shutdown systems, control panels, PLC systems, and centralized energy management platforms.

The ability to remotely open a circuit breaker is particularly important in industrial facilities where rapid isolation of electrical equipment is required for safety or operational reasons.

220-240V AC/DC Electrical Characteristics

The ABB 1SDA038292R0001 is designed for a control voltage range of 220-240V AC/DC. Supporting both alternating current and direct current control sources provides flexibility for different industrial electrical architectures.

This voltage compatibility allows the accessory to be integrated into various control systems used in factories, commercial buildings, energy facilities, and infrastructure applications. The stable electromagnetic operation ensures reliable activation of the breaker trip mechanism when a remote opening command is received.

The use of a dedicated trip coil design ensures fast response and consistent operation, which is essential for electrical protection systems where reliable circuit interruption is required.
