Why Choose the ABB E3L2000 PR121/P-LI 2000A Air Circuit Breaker Moving Part?
The ABB E3L2000 PR121/P-LI, order code 1SDA056736R1, is a SACE Emax moving part for a withdrawable air circuit breaker designed for high-current low-voltage power distribution systems. Part of the proven ABB SACE Emax E3L series, this three-pole configuration has a 2000 A rated current and is equipped with a PR121/P-LI R2000 electronic overcurrent release.
The PR121/P-LI trip unit provides long-time overload (L) and instantaneous short-circuit (I) protection, helping safeguard distribution equipment against sustained overcurrents and severe short circuits. The moving part is also fitted with four auxiliary contacts and circuit-breaker open/closed position indication for integration with switchboard control and signalling circuits.
Designed as the moving portion of a three-pole withdrawable E3L circuit breaker, the 1SDA056736R1 is intended to operate with the corresponding ABB SACE Emax fixed part. Its withdrawable construction supports inspection, maintenance and replacement while allowing the fixed portion of the circuit breaker assembly to remain installed in the switchboard.
