1SDA057141R1 ABB E6V6300 PR122/P-LSIG 6300A 3-Pole Fixed Air Circuit Breaker

Why Choose the ABB E6V6300 PR122/P-LSIG 6300A 3-Pole Fixed Air Circuit Breaker?

The ABB 1SDA057141R1, product designation E6V6300PR122/P-LSIGIn=6300A3pF, is a high-performance SACE Emax air circuit breaker designed for switching and protection in demanding low-voltage electrical distribution systems. Part of the ABB SACE Emax E6V series, this three-pole fixed circuit breaker combines a 6300 A rated current with the advanced PR122/P-LSIG electronic overcurrent release.

The E6V6300 is engineered for high-current industrial, commercial and infrastructure installations where comprehensive circuit protection and substantial fault-clearing capability are required. Its PR122/P-LSIG R6300 electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection, helping protect busbars, cables, switchgear and connected equipment while supporting selective coordination within complex electrical distribution networks.

The E6V performance level provides an ultimate short-circuit breaking capacity of up to 150 kA at 400–440 V AC, with high breaking performance maintained at higher operating voltages. This three-pole fixed version is suited to permanent integration into high-capacity switchboards and provides a robust protection solution for installations with substantial prospective fault currents.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E6V6300 provide switching and protection for high-capacity low-voltage distribution networks. With a rated current of 6300 A and V-level short-circuit performance, the E6V platform is particularly suited to main incoming supplies, large switchboards, transformer secondary systems and industrial distribution networks where substantial loads and high prospective fault currents must be safely managed.

The PR122/P-LSIG electronic release provides four complementary protection functions. Long-time protection responds to sustained overloads, short-time protection supports controlled fault clearing and selective coordination, instantaneous protection responds rapidly to severe short circuits, and ground-fault protection provides additional protection against earth-fault conditions. This combination makes the breaker well suited to sophisticated high-current distribution systems requiring comprehensive electronic protection.

Typical Applications

• Main low-voltage electrical distribution switchboards.
• High-current industrial power distribution systems.
• Large switchgear and busbar assemblies.
• Transformer secondary protection and distribution.
• Manufacturing and heavy process plants.
• Data centre and critical infrastructure power distribution.
• Commercial and infrastructure electrical installations.
• High-capacity distribution systems requiring selective LSIG protection.
