1SDA056608R1 ABB E3V1600 PR121/P-LI 1600 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E3V1600 PR121/P-LI 1SDA056608R1 Air Circuit Breaker?

The ABB 1SDA056608R1 is a high-performance SACE Emax E3 V withdrawable air circuit breaker (ACB) moving part designed for protection and switching in demanding low-voltage electrical distribution systems. As part of the ABB SACE Emax series, this three-pole breaker combines a 1600 A rated uninterrupted current with high short-circuit performance for industrial, commercial and infrastructure power distribution applications.

The E3V1600 is equipped with an ABB PR121/P-LI electronic overcurrent release, providing long-time overload and instantaneous short-circuit protection. These L and I protection functions provide dependable protection against sustained overcurrents and severe short-circuit faults, while the E3 V performance level is designed for electrical networks with high prospective fault currents.

With a rated uninterrupted current of 1600 A, a rated operational voltage of 690 V AC and a three-pole withdrawable configuration, the 1SDA056608R1 is well suited to main distribution boards, industrial switchgear and high-current feeder applications. The breaker provides a rated ultimate short-circuit breaking capacity of 130 kA at 400 V AC and is supplied as the moving part for a compatible SACE Emax withdrawable installation.

Reliable Circuit Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E3V1600 provide controlled switching and protection for high-current low-voltage distribution circuits. The PR121/P-LI electronic release provides long-time overload and instantaneous short-circuit protection, helping safeguard switchboards, conductors and connected electrical equipment against damaging overcurrent and fault conditions.

The E3 V performance level is designed for electrical networks where substantial prospective short-circuit currents may occur. Its withdrawable construction supports efficient maintenance and system availability by allowing the circuit-breaker moving part to be isolated and removed from a compatible fixed section without dismantling the main switchgear assembly.

Typical Applications

• Main low-voltage electrical distribution boards.
• Industrial withdrawable switchboards and switchgear assemblies.
• Manufacturing plants and process facilities.
• Commercial and infrastructure power distribution systems.
• High-current feeder and distribution circuit protection.
• Electrical installations requiring high short-circuit breaking capacity and serviceable switchgear.
