Why Choose the ABB 1SDA054623R1 PR222DS/P-LSI Electronic Trip Unit?

The ABB 1SDA054623R1 is a PR222DS/P-LSI electronic trip unit designed for compatible ABB SACE Tmax T4 moulded case circuit breakers. Rated at 250 A, this four-pole solid-state release provides electronic protection for demanding industrial and commercial low-voltage electrical distribution applications.

The PR222DS/P-LSI provides LSI protection functions, combining long-time overload protection (L), short-time short-circuit protection (S) and instantaneous short-circuit protection (I). These electronic protection functions support accurate circuit protection and coordination across electrical distribution systems where adjustable protection characteristics are required.

Designed specifically for the ABB SACE Tmax T4 platform, the 1SDA054623R1 has a rated current of 250 A and a four-pole configuration for AC applications. It is supplied as an electronic protection release for integration with compatible Tmax T4 breaker hardware and is therefore a circuit breaker component rather than a complete standalone MCCB.

Key Advantages

  • Genuine ABB PR222DS/P-LSI electronic trip unit.
  • 250 A rated current for compatible ABB Tmax T4 circuit breakers.
  • LSI electronic protection for overload and short-circuit conditions.
  • Long-time protection helps protect circuits against sustained overloads.
  • Short-time protection supports selective short-circuit protection.
  • Instantaneous protection provides rapid response to severe short-circuit faults.
  • Four-pole configuration for compatible four-pole Tmax T4 assemblies.
  • Modular design for combination with compatible ABB Tmax T4 breaker hardware.

Key Features

  • ABB PR222DS/P-LSI solid-state electronic protection release.
  • 250 A rated current (In).
  • Four-pole configuration.
  • Long-time (L) overload protection.
  • Short-time (S) short-circuit protection.
  • Instantaneous (I) short-circuit protection.
  • Electronic trip technology for compatible ABB Tmax T4 MCCBs.
  • Designed for AC applications.
  • Suitable for compatible ABB SACE Tmax T4 breaker assemblies.
  • Part of ABB's modular Tmax low-voltage circuit protection platform.

Electronic LSI Protection for ABB Tmax T4 Circuit Breakers

The PR222DS/P-LSI combines three important electronic protection functions within a single release. Long-time protection responds to sustained overload conditions, short-time protection provides a controlled response to short-circuit currents to support system selectivity, and instantaneous protection enables rapid tripping when severe short-circuit conditions occur.

The 1SDA054623R1 is the 250 A four-pole version intended for compatible ABB Tmax T4 circuit breaker hardware. Because it is a protection release rather than a complete MCCB, the final circuit breaker's interruption performance depends on the compatible T4 breaking part with which it is assembled. This modular architecture enables the breaker body and electronic protection release to be selected according to the requirements of the electrical installation.

Typical Applications

  • ABB Tmax T4 moulded case circuit breaker assemblies.
  • Industrial electrical distribution systems.
  • Commercial low-voltage distribution boards.
  • Four-pole AC feeder protection.
  • Three-phase and neutral distribution systems.
  • Industrial machinery and manufacturing facilities.
  • Electrical switchboards and distribution panels.
  • OEM switchgear and control panel assemblies.
