Why Choose the ABB E3S-A 800 PR121/P-LSIG Air Circuit Breaker?
The ABB E3S-A 800 PR121/P-LSIG, order code 1SDA060765R1, is a high-performance SACE Emax air circuit breaker designed for reliable switching and protection in demanding low-voltage power distribution systems. This three-pole withdrawable circuit breaker has a rated current of 800 A and incorporates ABB's PR121/P-LSIG electronic overcurrent release for comprehensive circuit protection.
As part of the ABB SACE Emax E3 series, the E3S-A is engineered for industrial, commercial and infrastructure installations requiring robust high-current protection and maintainable switchgear. The PR121/P-LSIG trip unit provides long-time, short-time, instantaneous and earth-fault protection functions, helping safeguard electrical systems against overloads and multiple types of short-circuit fault.
This specific E3S-A 800 configuration is supplied as a three-pole moving part for a withdrawable circuit breaker. The withdrawable format enables the breaker to be isolated and removed from its corresponding fixed part for inspection, maintenance or replacement, making it particularly suitable for critical switchboards where serviceability and continuity are important.

Comprehensive Protection for Power Distribution Systems
Air circuit breakers such as the ABB SACE Emax E3S-A provide switching and protection for major low-voltage distribution circuits. The PR121/P-LSIG electronic release combines long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection, enabling the breaker to respond appropriately to a broad range of electrical fault conditions.
The withdrawable construction provides an important advantage in installations where maintainability is a priority. The circuit-breaker moving part can be withdrawn from its corresponding fixed section for servicing or replacement, helping engineers maintain switchboards without the installation constraints associated with a permanently fixed breaker.
