Why Choose the ABB 1SDA054624R1 PR222DS/P-LSIG Electronic Trip Unit?
The ABB 1SDA054624R1 is a PR222DS/P-LSIG electronic trip unit designed for compatible ABB SACE Tmax T4 moulded case circuit breakers. Rated at 100 A, this four-pole electronic protection release provides comprehensive protection for industrial and commercial low-voltage electrical distribution applications.
The PR222DS/P-LSIG provides LSIG protection functions, combining long-time overload protection (L), short-time short-circuit protection (S), instantaneous short-circuit protection (I) and ground-fault protection (G). This combination enables a compatible Tmax T4 circuit breaker to respond to multiple electrical fault conditions while supporting coordinated protection throughout a distribution system.
Designed specifically for the ABB SACE Tmax T4 platform, the 1SDA054624R1 has a rated current of 100 A and a four-pole configuration. 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-LSIG electronic trip unit.
- 100 A rated current for compatible ABB Tmax T4 circuit breakers.
- Comprehensive LSIG electronic protection.
- Long-time protection for sustained overload conditions.
- Short-time protection supports selective response to short-circuit faults.
- Instantaneous protection provides rapid response to severe short circuits.
- Integrated ground-fault protection for additional earth-fault protection.
- Four-pole configuration for compatible four-pole Tmax T4 assemblies.
Key Features
- ABB PR222DS/P-LSIG electronic protection release.
- 100 A rated current (In).
- Four-pole configuration.
- Long-time (L) overload protection.
- Short-time (S) short-circuit protection.
- Instantaneous (I) short-circuit protection.
- Ground-fault (G) protection.
- Electronic trip technology for compatible ABB Tmax T4 MCCBs.
- Designed for compatible ABB SACE Tmax T4 circuit breaker hardware.
- Part of ABB's modular Tmax low-voltage circuit protection platform.
Comprehensive LSIG Protection for ABB Tmax T4 Circuit Breakers
The PR222DS/P-LSIG combines four electronic protection functions within a single trip unit. Long-time protection responds to sustained overload conditions, short-time protection provides a controlled response to short-circuit currents, instantaneous protection enables rapid tripping during severe short circuits, and ground-fault protection provides an additional response to earth-fault conditions.
The 1SDA054624R1 is the 100 A four-pole version for compatible ABB Tmax T4 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 allows the breaker body and protection functions 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 feeder protection.
- Three-phase and neutral distribution systems.
- Applications requiring ground-fault protection.
- Electrical switchboards and distribution panels.
- OEM switchgear and control panel assemblies.
