Why Choose the ABB PR221DS-LS/I In=160 T4 4P?
The ABB PR221DS-LS/I In=160 T4 4P, order code 1SDA054616R1, is an electronic protection release designed for compatible ABB SACE Tmax T4 moulded case circuit breaker assemblies. With a rated current of 160 A and a four-pole configuration, it provides electronic protection for industrial and commercial AC power distribution circuits.
The PR221DS-LS/I release provides long-time overload and short-circuit protection functions, enabling the completed Tmax T4 assembly to respond to sustained overcurrents and high-current fault conditions. Its electronic protection technology supports coordinated circuit protection while retaining the modular flexibility of the ABB Tmax platform.
The 1SDA054616R1 is supplied as a protection release rather than a complete moulded case circuit breaker. It is intended to be combined with a compatible ABB Tmax T4 breaking part and associated operating components to form the required complete MCCB configuration.
Key Advantages
- Genuine ABB PR221DS-LS/I electronic protection release.
- 160 A rated current for compatible Tmax T4 assemblies.

Electronic Protection for ABB SACE Tmax T4
The electronic release forms the protection element of a compatible moulded case circuit breaker assembly. It monitors current conditions and initiates operation of the circuit breaker mechanism when the applicable protection thresholds are exceeded, while the associated Tmax T4 breaking part physically interrupts the current.
With a rated current of 160 A and a four-pole configuration, the 1SDA054616R1 provides a practical protection solution for compatible T4 assemblies used in industrial and commercial distribution systems. Its PR221DS-LS/I functionality combines overload and short-circuit protection in a modular ABB Tmax component.
Typical Applications
- Compatible ABB SACE Tmax T4 moulded case circuit breaker assemblies.
- 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.
