1SDA061187R1 ABB E4L-A 3200 PR122/P-LSI 3200A 3P Air Circuit Breaker

Why Choose the ABB E4L-A 3200 PR122/P-LSI 3200A 3P Air Circuit Breaker?

The ABB E4L-A 3200 PR122/P-LSI, order code 1SDA061187R1, is a high-capacity SACE Emax air circuit breaker engineered for protection and switching in demanding low-voltage power-distribution systems. Rated at 3200 A, this three-pole E4L-A configuration combines substantial current-handling capability with ABB's advanced PR122/P-LSI electronic overcurrent release.

The PR122/P-LSI electronic release provides long-time, short-time and instantaneous protection, delivering LSI protection against overload and short-circuit conditions. Adjustable electronic protection supports coordination between protective devices, making the breaker suitable for complex distribution networks where selective fault isolation and dependable operation are important.

With its 3200 A rated current, three-pole configuration and E4L-A performance level, the 1SDA061187R1 is designed for high-capacity distribution duties such as main incomers, bus-couplers and major feeders. It forms part of ABB's New Emax range for industrial, commercial and infrastructure installations requiring robust high-current circuit protection.

Reliable Protection for High-Capacity Power Distribution

The ABB SACE Emax E4L-A protects low-voltage electrical networks by monitoring current conditions and interrupting the circuit when configured protection thresholds are exceeded. This helps protect busbars, cables, switchgear and connected equipment against the damaging thermal and electromagnetic effects associated with overloads and short-circuit faults.

Its PR122/P-LSI electronic release combines long-time overload protection with short-time and instantaneous short-circuit protection. Together with the breaker's 3200 A current rating, these functions make the E4L-A suitable for high-capacity distribution systems where dependable fault interruption and coordination between upstream and downstream protective devices are required.

Typical Applications

• Industrial low-voltage main distribution switchboards.
• High-capacity main incoming supply protection.
• Bus-coupler and sectionalising applications.
• Major feeder and distribution circuit protection.
• Manufacturing and process-industry electrical systems.
• Commercial and infrastructure power-distribution installations.
