1SDA061329R1 ABB E6L-A 5000 PR123/P-LSIG 5000 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E6L-A 5000 PR123/P-LSIG 1SDA061329R1 Air Circuit Breaker?

The ABB 1SDA061329R1 is a high-current E6L-A 5000 A three-pole withdrawable air circuit breaker moving part from the ABB SACE Emax / New Emax range, engineered for demanding low-voltage power distribution systems. Equipped with the advanced PR123/P-LSIG electronic overcurrent release, it provides long-time, short-time, instantaneous and earth-fault protection for high-capacity industrial, commercial and infrastructure installations.

This configuration combines the E6L-A breaker platform with an R5000 overcurrent release and an Im 75000 A instantaneous setting reference. Its withdrawable moving-part construction is designed for use with a compatible ABB SACE Emax fixed part, supporting efficient inspection, maintenance and replacement within critical switchboard installations.

With a rated current of 5000 A, three-pole construction and UL configuration, the 1SDA061329R1 is designed for exceptionally high-current three-phase distribution. It is also fitted with four auxiliary contacts and open/closed position indication, supporting integration with switchboard status monitoring and control systems.

Advanced High-Current Protection for Power Distribution

Air circuit breakers such as the ABB E6L-A provide protection, switching and isolation within very high-current low-voltage electrical networks. They are particularly suited to main distribution switchboards and large power distribution assemblies where substantial electrical loads require dependable protection against overload, short-circuit and earth-fault conditions.

The PR123/P-LSIG electronic release provides long-time protection against sustained overloads, short-time protection to support selective coordination, instantaneous protection against severe short circuits and earth-fault protection. Combined with the withdrawable E6L-A platform, these functions provide comprehensive and serviceable protection for large industrial plants, infrastructure installations and other high-capacity low-voltage distribution systems.

Typical Applications

• Very high-current low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Large commercial and infrastructure electrical installations.
• Manufacturing and process plant switchgear.
• Main incomers and high-capacity distribution feeders.
• Power distribution and control assemblies.
• Withdrawable switchboard installations requiring 5000 A three-pole LSIG protection.
