1SDA056696R1 ABB E3V3200 PR121/P-LI 3200 A 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E3V3200 PR121/P-LI Air Circuit Breaker?

The ABB E3V3200 PR121/P-LI, order code 1SDA056696R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for switching and protection in high-current low-voltage power-distribution systems. Part of the ABB SACE Emax E3 series, this four-pole fixed circuit breaker combines a 3200 A rated current with the PR121/P-LI R3200 electronic overcurrent release.

The PR121/P-LI release provides long-time overload and instantaneous short-circuit protection, helping protect switchboards, conductors and downstream electrical equipment against damaging overcurrents. The E3V performance version is intended for demanding industrial and infrastructure installations where high current capacity and robust fault protection are required.

This configuration is a four-pole fixed circuit breaker equipped with rear horizontal terminals. It also incorporates four auxiliary contacts and open/closed circuit-breaker position indication, supporting integration into switchboard monitoring, signalling and control systems.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E3V3200 provide switching and overcurrent protection at main incomer and feeder levels within low-voltage distribution systems. The PR121/P-LI electronic release monitors circuit current and provides long-time protection against sustained overload conditions together with instantaneous intervention when severe short-circuit currents occur.

The combination of a 3200 A current rating, four-pole construction and E3V performance level makes this circuit breaker particularly suitable for substantial industrial and commercial power-distribution installations. Its fixed design and rear horizontal terminals enable permanent integration into switchboards, while the auxiliary contacts provide status information for associated control and signalling systems.

Typical Applications

• Main low-voltage distribution switchboards.
• Industrial power-distribution systems.
• Manufacturing and process plants.
• Commercial and infrastructure electrical installations.
• Transformer secondary and main incomer protection.
• High-current feeder protection.
• Power distribution and control assemblies.
