Why Choose the ABB E3N3200 PR121/P-LI 3200A 4P Fixed Air Circuit Breaker?
The ABB 1SDA056152R1 is a high-performance SACE Emax E3N air circuit breaker (ACB) designed for switching and protection in demanding low-voltage electrical distribution systems. Part of the ABB New Emax product group, this four-pole fixed circuit breaker combines a 3200 A rated uninterrupted current with the PR121/P-LI R3200 electronic overcurrent release for dependable protection of industrial, commercial and infrastructure power networks.
The E3N3200 provides long-time and instantaneous protection through its LI trip functionality. The PR121/P electronic release protects against overload and instantaneous short-circuit conditions, with an overload adjustment range of 1280–3200 A and an instantaneous short-circuit release adjustment range of 4800–48000 A. This LI configuration does not include short-time delayed or integrated earth-fault protection.
With a rated uninterrupted current of 3200 A, a 690 V AC rated operational voltage and an ultimate short-circuit breaking capacity of 65 kA at 415 V AC, the E3N3200 provides robust protection for high-current distribution systems. This version features a four-pole fixed configuration with rear flat horizontal terminals, four auxiliary contacts and circuit-breaker open/closed position indication for permanent integration into low-voltage switchgear.
