Why Choose the ABB 1SDA054612R1 PR222DS/P-LSIG Electronic Trip Unit?
The ABB 1SDA054612R1 is a PR222DS/P-LSIG electronic trip unit designed for compatible ABB SACE Tmax T4 moulded case circuit breakers. Rated at 100 A, this three-pole electronic 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 protect against multiple electrical fault conditions while supporting coordinated protection within a distribution system.
Designed specifically for the ABB SACE Tmax T4 platform, the 1SDA054612R1 has a rated current of 100 A and a three-pole configuration. It is supplied as a protection release for integration with a compatible T4 breaking part 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 helps protect against sustained overload conditions.
- Short-time and instantaneous functions provide short-circuit protection.
- Integrated ground-fault protection adds protection against earth-fault conditions.
- Three-pole configuration for compatible three-phase installations.
- Modular design for combination with a suitable ABB Tmax T4 breaking part.
Key Features
- ABB PR222DS/P-LSIG electronic protection release.
- 100 A rated current (In).
- Three-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 specifically for the ABB SACE Tmax T4 platform.
- Suitable for demanding industrial, commercial and OEM electrical distribution applications.
Comprehensive LSIG Protection for ABB Tmax T4 Circuit Breakers
The PR222DS/P-LSIG combines four important electronic protection functions within one trip unit. Long-time protection responds to sustained overloads, short-time protection enables a controlled response to short-circuit conditions, instantaneous protection provides rapid tripping during severe faults, and ground-fault protection detects earth-fault conditions requiring interruption.
The 1SDA054612R1 is the 100 A three-pole version for compatible ABB Tmax T4 hardware. Because it is a protection release rather than a complete MCCB, characteristics such as the final circuit breaker's short-circuit breaking capacity depend on the compatible T4 breaking part with which the release is assembled. This modular approach enables the breaker body and protection functions to be selected to suit the electrical installation.
Typical Applications
- ABB Tmax T4 moulded case circuit breaker assemblies.
- Industrial electrical distribution systems.
- Commercial low-voltage distribution boards.
- Three-phase feeder protection.
- Applications requiring ground-fault protection.
- Industrial machinery and manufacturing facilities.
- Electrical switchboards and distribution panels.
- OEM switchgear and control panel assemblies.
