Why Choose the ABB E1B1000 PR123/P-LSIG 1000A 3-Pole Withdrawable Circuit Breaker?
The ABB E1B1000 PR123/P-LSIG, order code 1SDA059202R1, is a high-performance SACE Emax air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. Part of the proven ABB SACE Emax E1B series, this three-pole withdrawable breaker is rated at 1000 A and incorporates the advanced PR123/P-LSIG R1000 electronic overcurrent release.
The PR123/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. This electronic protection platform is well suited to industrial switchboards and critical power distribution systems requiring accurate protection and dependable operation.
This version is a three-pole withdrawable moving part for the SACE Emax system and is supplied with four auxiliary contacts for circuit-breaker open/closed position indication. Its withdrawable construction facilitates inspection, servicing and replacement while allowing the breaker moving part to be isolated from the main circuit within a compatible Emax fixed part.
