1SDA060695R1 ABB E2N-A 800 PR121/P-LSI 800 A 3P Fixed Air Circuit Breaker

Why Choose the ABB E2N-A 800 PR121/P-LSI In=800A 3p F?

The ABB E2N-A 800 PR121/P-LSI In=800A 3p F, order code 1SDA060695R1, is a SACE Emax E2N-A fixed air circuit breaker engineered for industrial low-voltage power distribution. It combines an 800 A current rating with ABB's electronic PR121/P-LSI trip unit, providing configurable protection for demanding switchboard and distribution applications.

This circuit breaker uses a three-pole fixed configuration with horizontal rear (HR) terminals. The E2N-A 08 frame provides a rated short-circuit capability of 50 kA at 480 V AC, while its fixed mounting arrangement is well suited to installations where a permanently connected breaker is preferred.

The integrated PR121/P electronic release provides LSI protection, combining long-time overload, short-time short-circuit and instantaneous short-circuit protection. Designed to UL 1066, the breaker is rated at 800 A and 600 V, making it a capable solution for industrial distribution systems requiring dependable electronic protection and substantial fault interruption performance.

Reliable Protection for Industrial Power Distribution

The ABB E2N-A platform combines the robust switching architecture of the SACE Emax family with electronic protection suited to industrial distribution systems. The fixed three-pole design and horizontal rear terminals make the 1SDA060695R1 particularly suitable for switchboards where a permanently installed breaker and rear busbar connections are required.

Its PR121/P-LSI release continuously supports protection against overload and short-circuit conditions through long-time, short-time and instantaneous functions. Together with an 800 A current rating and 50 kA service short-circuit breaking capacity at 480 V AC, this provides a strong combination of protection, selectivity potential and fault interruption performance.
