Why Choose the ABB E1B 1600 PR123/P-LSIG 1600A Air Circuit Breaker?
The ABB E1B 1600 PR123/P-LSIG, order code 1SDA055695R1, is a high-performance 1600 A four-pole withdrawable air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. Part of the established ABB SACE Emax / New Emax range, it combines the E1B frame's robust circuit-breaking capability with the advanced PR123/P-LSIG R1600 electronic overcurrent release.
The fitted PR123/P-LSIG R1600 electronic trip unit provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection. This comprehensive LSIG configuration supports selective and coordinated protection strategies while helping safeguard cables, busbars, switchgear and connected equipment against overloads, short circuits and earth faults.
Supplied as a withdrawable moving part, this four-pole breaker is designed for use with the appropriate ABB SACE Emax fixed part or cradle. Its withdrawable construction facilitates isolation, inspection and maintenance, while four auxiliary contacts and open/closed circuit-breaker position indication support integration with switchboard signalling, monitoring and control systems.

Advanced LSIG Protection for 1600A Four-Pole Power Distribution
Air circuit breakers such as the ABB SACE Emax E1B protect high-current electrical distribution systems by detecting and interrupting abnormal current conditions before cables, busbars, switchgear and connected equipment can sustain serious damage. The E1B 1600 combines a continuous current capability of 1600 A with 42 kA ultimate and service short-circuit breaking capacities across its specified 220–690 V AC operating range.
The PR123/P-LSIG electronic release combines long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection within one advanced trip unit. The short-time function supports selective coordination with downstream protective devices, while the G function extends protection to earth-fault conditions. Combined with four-pole switching and withdrawable construction, the 1SDA055695R1 is particularly suited to sophisticated three-phase four-wire distribution systems requiring comprehensive protection and convenient maintenance access.
Typical Applications
- Industrial low-voltage distribution switchboards.
- Main incoming circuit protection.
