Why Choose the ABB E1B1000 PR121/P-LSIG 1000A 4-Pole Withdrawable Circuit Breaker?

The ABB E1B1000 PR121/P-LSIG, order code 1SDA059180R1, is a high-performance SACE Emax air circuit breaker moving part designed for protection and switching of high-current low-voltage electrical distribution systems. Part of the proven ABB SACE Emax E1B series, this four-pole breaker is rated at 1000 A and incorporates the PR121/P-LSIG electronic overcurrent release.

The PR121/P-LSIG protection unit provides comprehensive long-time, short-time, instantaneous and earth-fault protection, helping protect electrical installations against overloads, short circuits and ground faults. Its electronic protection architecture makes the E1B1000 suitable for industrial switchboards, power distribution assemblies and other installations requiring dependable selective circuit protection.

This version is a four-pole withdrawable moving part for the SACE Emax system and is supplied with four auxiliary contacts for circuit-breaker open/closed position indication. The withdrawable configuration facilitates inspection and maintenance while allowing the breaker moving part to be isolated from the main circuit within a compatible Emax fixed part.
