Why Choose the ABB 1SDA055701R1 E1N 800 Air Circuit Breaker?

The ABB 1SDA055701R1 is a high-performance SACE Emax E1N 800 air circuit breaker designed for reliable protection and switching in low-voltage power distribution systems. Rated at 800 A, this three-pole fixed circuit breaker incorporates an advanced PR122/P-LSIG electronic overcurrent release for comprehensive protection against overloads, short circuits and ground faults.

As part of the proven ABB SACE Emax range, the E1N 800 combines robust high-current switching with sophisticated electronic protection for demanding industrial, commercial and infrastructure installations. The PR122/P-LSIG R800 release provides long-time, short-time, instantaneous and ground-fault protection functions, supporting effective protection coordination throughout low-voltage distribution networks.

This configuration features a three-pole fixed design with horizontal rear terminals and a rated current of 800 A. It is also equipped with four auxiliary circuit-breaker contacts for open/closed position indication, providing useful status signalling for integration into switchboard control and monitoring systems.

Key Advantages

  • Heavy-duty 800 A SACE Emax air circuit breaker for low-voltage power distribution.
  • Three-pole fixed configuration for permanent switchboard installations.
  • Advanced PR122/P-LSIG R800 electronic overcurrent release.
  • LSIG functionality provides long-time, short-time, instantaneous and ground-fault protection.
  • E1N performance level for demanding industrial and commercial distribution applications.
  • Horizontal rear terminals simplify integration into compatible switchboard arrangements.
  • Includes four auxiliary contacts for circuit-breaker open/closed position indication.

Key Features

  • ABB SACE Emax E1N 800 circuit breaker platform.
  • 800 A rated current.
  • Three-pole configuration.
  • Fixed (F) execution.
  • Horizontal rear (HR) terminals.
  • PR122/P-LSIG R800 electronic overcurrent release.
  • Long-time, short-time, instantaneous and ground-fault protection functions.
  • 50 kA E1N short-circuit breaking performance at 380/415 V AC.
  • Four auxiliary circuit-breaker contacts.
  • Open/closed circuit-breaker position indication.

Advanced Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax E1N are designed to switch and protect high-current low-voltage distribution circuits. By combining a robust circuit-breaker mechanism with an electronic protection release, the breaker can detect abnormal current conditions and disconnect the circuit before overloads, short circuits or ground faults cause extensive damage to cables, busbars and connected electrical equipment.

The PR122/P-LSIG release provides comprehensive long-time, short-time, instantaneous and ground-fault protection. Combined with the E1N 800 frame, fixed construction and horizontal rear terminals, this makes the ABB 1SDA055701R1 a practical solution for main distribution, incomer and feeder protection within demanding industrial and commercial switchboards.

Typical Applications

  • Main low-voltage switchboards and distribution boards.
  • Industrial power distribution systems.
  • Commercial and infrastructure electrical installations.
  • Main incomer and feeder circuit protection.
  • Manufacturing and process plant switchgear.
  • Distribution systems requiring electronic ground-fault protection.
