Why Choose the ABB E3H 1600 PR123/P-LSIG 1600A 4P Fixed Air Circuit Breaker?
The ABB 1SDA056415R1 is a high-performance SACE Emax E3H air circuit breaker designed for switching and protection in demanding low-voltage power distribution systems. Rated at 1600 A, this four-pole fixed circuit breaker incorporates ABB's advanced PR123/P-LSIG R1600 electronic overcurrent release, providing comprehensive protection for high-current industrial, commercial and infrastructure electrical networks.
Part of the ABB SACE Emax E3 series, the E3H 1600 combines a substantial 1600 A current rating with high short-circuit interruption performance. The E3H frame provides a rated ultimate short-circuit breaking capacity of 100 kA at 400 V AC, making it suitable for installations where high prospective fault currents require robust circuit protection.
The PR123/P-LSIG release provides long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. This version features a four-pole fixed configuration with rear horizontal terminals and is supplied with four auxiliary contacts plus circuit-breaker open/closed position indication for integration into compatible low-voltage switchboards.

Advanced PR123/P-LSIG Protection for High-Current Distribution
Air circuit breakers such as the ABB E3H 1600 provide switching, isolation and automatic protection for important low-voltage distribution circuits. The PR123/P electronic overcurrent release monitors circuit conditions and commands the breaker to open when configured overload, short-circuit or earth-fault thresholds are reached, helping protect conductors, busbars, switchgear and connected equipment.
The PR123/P-LSIG release combines long-time, short-time, instantaneous and earth-fault protection functions for comprehensive protection and coordination within sophisticated electrical networks. Combined with the E3H frame's 100 kA ultimate breaking capacity at 400 V AC and fixed rear-horizontal-terminal arrangement, the 1SDA056415R1 is particularly suited to permanent switchboard installations requiring advanced electronic protection and dependable 1600 A power distribution.
Typical Applications
- Main incoming protection in low-voltage switchboards.
- Industrial power distribution systems.
- High-fault-level feeder and distribution circuits.
- Manufacturing and process plant electrical systems.
- Commercial and infrastructure power distribution.
- Transformer-fed low-voltage distribution boards.
- Generator and standby power switchboards.
- Critical installations requiring advanced LSIG electronic protection.
