1SDA056096R1 ABB E2L1600 PR121/P-LI 1600 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E2L1600 PR121/P-LI 1SDA056096R1 Air Circuit Breaker?

The ABB 1SDA056096R1 is a high-performance SACE Emax E2L1600 air circuit breaker moving part designed for switching and protection in demanding low-voltage electrical distribution systems. Part of the ABB New Emax range, this three-pole withdrawable circuit breaker has a rated current of 1600 A and incorporates a PR121/P-LI R1600 electronic overcurrent release.

The PR121/P-LI trip unit provides long-time overload and instantaneous short-circuit protection, helping protect conductors, switchgear and connected equipment against damaging overcurrent conditions. The E2L performance class provides high short-circuit interruption capability, including an ultimate and service short-circuit breaking capacity of 130 kA at 400 V AC.

With an operational voltage rating of up to 690 V AC, three-pole configuration and withdrawable moving-part construction, the E2L1600 is particularly suitable for high-current switchboards where maintainability and operational flexibility are important. The moving part is fitted with four auxiliary contacts and open/closed position indication for integration with switchboard control and signalling systems.
