Why Choose the ABB 1SDA054871R1 SOR-C Shunt Opening Release?

The ABB 1SDA054871R1 is a wired shunt opening release (SOR-C) designed for remote electrical tripping of compatible ABB SACE Tmax T4, T5 and T6 moulded case circuit breakers. Operating from a 48–60 V AC/DC control supply, this genuine ABB accessory enables the circuit breaker to be opened electrically from an external control or safety circuit.

As part of the ABB SACE Tmax T accessory range, the SOR-C provides a dependable means of integrating circuit breaker opening into industrial control, emergency shutdown and automation systems. When the release receives its specified control voltage, it actuates the breaker opening mechanism, allowing remote disconnection without manual operation at the breaker.

The 1SDA054871R1 is the cabled SOR-C version for T4, T5 and T6 applications. Its dual AC/DC control-voltage capability provides flexibility in panel design, while its dedicated ABB construction ensures compatibility with the corresponding Tmax circuit breaker platform.

Reliable Remote Opening for Tmax Circuit Breakers

A shunt opening release allows a circuit breaker to be tripped by an external electrical signal. This enables the breaker to form part of automated control and safety systems where electrical isolation must be initiated remotely rather than through direct manual operation.

The ABB 1SDA054871R1 provides this functionality for compatible Tmax T4, T5 and T6 circuit breakers using a 48–60 V AC/DC control supply. It is suitable for applications such as emergency-stop systems, process shutdown controls, remote isolation and building or industrial automation schemes.

Typical Applications

  • Remote tripping of ABB Tmax T4, T5 and T6 circuit breakers.
  • Industrial emergency shutdown systems.
  • Automated electrical distribution panels.
  • Machine and process safety circuits.
  • Low-voltage switchboards and motor control systems.
  • Building management and remote isolation systems.
