Why Choose the ABB SOR T4-T5-T6 220–240 V AC / 220–250 V DC Shunt Opening Release?

The ABB SOR T4-T5-T6, order code 1SDA054866R1, is a shunt opening release for ABB SACE Tmax T4, T5 and T6 moulded-case circuit breakers. It provides electrically initiated remote opening of a compatible circuit breaker when the specified control voltage is applied to the release.

This version operates at 220–240 V AC or 220–250 V DC, providing compatibility with widely used auxiliary and control supply voltages. The SOR can be incorporated into remote trip, protection, automation and emergency-opening circuits where a compatible Tmax circuit breaker must be opened electrically rather than solely by local manual operation.

The 1SDA054866R1 is the uncabled version of the SOR for the Tmax T4, T5 and T6 families. As a genuine ABB service release accessory, it provides a manufacturer-engineered solution for adding remote electrical opening functionality to compatible low-voltage moulded-case circuit breakers.

Key Advantages

  • Genuine ABB SOR shunt opening release for compatible SACE Tmax circuit breakers.
  • Compatible with ABB SACE Tmax T4, T5 and T6 circuit breaker families.
  • Rated for 220–240 V AC and 220–250 V DC control supplies.
  • Enables electrical remote opening of the circuit breaker.
  • Suitable for integration with automation, protection and emergency trip circuits.
  • ABB-engineered accessory designed specifically for the compatible Tmax platform.

Key Features

  • SOR shunt opening release.
  • 220–240 V AC rated control voltage.
  • 220–250 V DC rated control voltage.
  • Uncabled version.
  • Compatible with Tmax T4, T5 and T6.
  • Provides electrically controlled circuit breaker opening.
  • Suitable for remote trip and emergency-opening applications.
  • Designed for compatible ABB moulded-case circuit breakers.

Remote Circuit Breaker Opening for Automation and Safety Systems

A shunt opening release allows a circuit breaker to be opened electrically from a remote control point. When the appropriate control voltage is applied to the ABB SOR 1SDA054866R1, the release actuates the opening mechanism of the compatible Tmax circuit breaker, enabling remote disconnection without requiring direct manual operation at the breaker.

This functionality is valuable in industrial automation, building services, process control and electrical safety systems where circuit breakers may need to respond to remote pushbuttons, protection relays or emergency shutdown commands. Its 220–240 V AC / 220–250 V DC rating allows the accessory to integrate with either AC or DC control circuits operating within the specified voltage ranges.

Typical Applications

  • Remote circuit breaker opening and tripping.
  • Emergency shutdown and emergency-opening circuits.
  • Industrial automation and process control systems.
  • Building management and electrical control systems.
  • Low-voltage distribution switchboards.
  • ABB SACE Tmax T4, T5 and T6 circuit breaker installations.
