1SDA056695R1 ABB E3V3200 PR123/P-LSIG 3200A 3P Fixed Air Circuit Breaker

Why Choose the ABB E3V3200 PR123/P-LSIG 3200A 3P Fixed Air Circuit Breaker?

The ABB E3V3200 PR123/P-LSIG, order code 1SDA056695R1, is a high-performance SACE Emax air circuit breaker (ACB) engineered for advanced switching and protection in demanding low-voltage power distribution systems. Part of the ABB SACE Emax E3 series, this three-pole fixed breaker combines a 3200 A rated uninterrupted current with the advanced PR123/P-LSIG R3200 electronic overcurrent release.

The E3V3200 is supplied in a fixed three-pole configuration with horizontal rear terminals, providing a practical arrangement for high-current busbar connections within industrial switchboards and distribution assemblies. Its PR123/P-LSIG electronic release provides long-time, short-time, instantaneous and earth-fault protection, helping protect busbars, cables, transformers and connected equipment against overloads, short circuits and earth faults.

With a rated voltage of 690 V and a rated ultimate short-circuit breaking capacity of 130 kA at 400 V AC, 50 Hz, the E3V3200 is suited to installations with demanding prospective fault levels. Four change-over auxiliary contacts and open/closed circuit-breaker position indication further support integration with switchboard monitoring, signalling and control systems.
