Why Choose the ABB PR221DS-LS/I In=100 T4 4P?
The ABB PR221DS-LS/I In=100 T4 4P, order code 1SDA054615R1, is a solid-state electronic protection release designed for compatible ABB SACE Tmax T4 moulded case circuit breakers. Rated at 100 A, this four-pole release provides electronic protection functions for AC power distribution applications.
The PR221DS-LS/I combines long-time overload protection with short-circuit protection, providing the core protection functions required for many industrial feeder and distribution circuits. Its electronic design enables more controlled protection characteristics than conventional fixed thermal-magnetic solutions and is intended to operate as part of a compatible Tmax T4 circuit breaker assembly.
The 1SDA054615R1 is specifically configured for four-pole Tmax T4 applications and has a rated current of 100 A. It is supplied as a protection release rather than a complete circuit breaker and must therefore be combined with a compatible ABB Tmax T4 breaking part and associated components to form the required complete MCCB.
Key Advantages
- Genuine ABB SACE Tmax T4 electronic protection release.
- 100 A rated current for compatible T4 circuit breaker assemblies.
- Four-pole (4P) configuration.
- PR221DS-LS/I electronic protection technology.

- Designed specifically for compatible ABB Tmax T4 moulded case circuit breakers.
- Electronic protection provides configurable response characteristics for coordinated distribution systems.
- Modular construction allows the release to be combined with the appropriate compatible T4 breaking unit.
Key Features
- ABB PR221DS-LS/I series.
- Rated current (In): 100 A.
- Four-pole (4P) version.
- Designed for the ABB SACE Tmax T4 platform.
- Solid-state electronic release.
- Designed for AC applications.
- LS/I protection functionality for overload and short-circuit protection.
- Undelayed short-circuit release adjustment range of 100–1000 A.
- Suitable for use with compatible power circuit breakers.
- Supplied as a protection release rather than a complete MCCB.
Electronic Protection for ABB SACE Tmax T4
The electronic release is the protection element of a compatible moulded case circuit breaker assembly. It monitors current conditions and commands the breaker mechanism to trip when the configured protection thresholds are exceeded. The PR221DS-LS/I is designed to provide overload and short-circuit protection for compatible Tmax T4 installations while the associated breaking part performs the physical interruption of the circuit.
With a rated current of 100 A and a four-pole configuration, the 1SDA054615R1 is suitable for compatible T4 assemblies used in industrial and commercial distribution systems. Its 100–1000 A undelayed short-circuit release adjustment range enables the protection response to be coordinated with the requirements of the circuit and other protective devices in the distribution system.
Typical Applications
- Compatible ABB SACE Tmax T4 moulded case circuit breakers.
- Industrial electrical distribution systems.
- Four-pole feeder protection.
- Electrical switchboards and distribution panels.
- Commercial building power distribution.
- Industrial machinery and process equipment.
- OEM electrical distribution assemblies.
- Applications requiring electronic overload and short-circuit protection.
