1SDA061199R1 ABB E4L-A 3200 PR123/P-LSIG 3200 A 3-Pole Fixed Air Circuit Breaker

Why Choose the ABB E4L-A 3200 PR123/P-LSIG 1SDA061199R1 Air Circuit Breaker?

The ABB E4L-A 3200 PR123/P-LSIG, order code 1SDA061199R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for protection and switching in demanding low-voltage electrical distribution systems. As part of the ABB New Emax E4 series, it combines a substantial 3200 A rated current with advanced electronic protection and a fixed-mounted construction for industrial, commercial and infrastructure power-distribution applications.

This three-pole circuit breaker is equipped with an ABB PR123/P-LSIG R3200 electronic overcurrent release, providing long-time, short-time, instantaneous and ground-fault protection. These LSIG functions provide comprehensive protection against overloads, short circuits and ground faults, making the breaker suitable for important distribution circuits where dependable and coordinated protection is required.

With a rated current of 3200 A, a three-pole fixed configuration and rear horizontal terminals, the E4L-A 3200 provides a robust solution for permanent installation within compatible low-voltage switchgear. Its high-performance construction provides a 150 kA short-circuit current rating at 480 V and a 100 kA short-time current rating, making it particularly suitable for installations with very high prospective fault currents.

Advanced Circuit Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax E4L-A provide switching and protection for high-current low-voltage distribution circuits. By combining a robust circuit-breaking mechanism with an advanced electronic protection release, the breaker can detect abnormal electrical conditions and disconnect the affected circuit to help protect conductors, switchgear and connected equipment.

The PR123/P-LSIG R3200 trip unit provides long-time protection against sustained overloads, short-time protection for coordinated response to short-circuit conditions, instantaneous protection against severe fault currents and ground-fault protection. Combined with the E4L-A frame's 150 kA short-circuit current rating at 480 V and 100 kA short-time current rating, these functions provide comprehensive protection for demanding high-current distribution systems.

Typical Applications

• High-current industrial low-voltage switchboards.
• Main incoming circuit protection.
• High-capacity electrical feeder protection.
• Power distribution in manufacturing and processing facilities.
• Commercial and infrastructure electrical installations.
• Industrial plant and facility power distribution.
