1SDA058306R1 ABB E2S 800 PR121/P-LI 800 A 4-Pole Draw-Out Moving Part

Why Choose the ABB E2S 800 PR121/P-LI 800 A 4-Pole Moving Part?

The ABB 1SDA058306R1 is a SACE Emax E2S 800 A four-pole moving part designed for a compatible withdrawable air circuit breaker installation. Combining the E2S short-circuit performance level with an ABB PR121/P-LI R800 electronic overcurrent release, it provides dependable overload and instantaneous short-circuit protection for demanding low-voltage power distribution systems.

Rated at 800 A, this four-pole moving portion is intended for use with the appropriate SACE Emax E2S draw-out fixed part. The withdrawable arrangement facilitates inspection, maintenance and replacement by allowing the breaker moving portion to be disconnected and removed from its compatible cradle, making it particularly suitable for switchboards where serviceability is important.

ABB order code 1SDA058306R1 is supplied with the PR121/P-LI R800 electronic release, four auxiliary contacts and circuit breaker open/closed position indication. The LI protection configuration provides Long-time overload protection and Instantaneous short-circuit protection, while the E2S platform delivers high fault-interruption capability for industrial and commercial electrical distribution.
