1SDA061207R1 ABB E4L-A 3600 PR121/P-LSI 3600 A 3-Pole Fixed Air Circuit Breaker

Why Choose the ABB 1SDA061207R1 E4L-A 3600 Air Circuit Breaker?

The ABB 1SDA061207R1 is a high-performance E4L-A 3600 fixed air circuit breaker (ACB) designed for protection and switching in demanding high-current low-voltage power distribution systems. Part of the established ABB SACE Emax series, this three-pole breaker combines a substantial 3600 A rated current with the PR121/P electronic overcurrent release for dependable protection in major industrial, commercial and infrastructure installations.

The breaker is equipped with an ABB PR121/P electronic trip unit with LSI protection functions, providing long-time overload, short-time short-circuit and instantaneous short-circuit protection. The short-time protection function supports selective coordination between protective devices, helping isolate faults while maintaining continuity in unaffected sections of the electrical distribution system.

This version features a fixed three-pole configuration with rear horizontal terminals and an R3600 overcurrent release. It is also equipped with four auxiliary contacts and open/closed position indication, providing useful status signalling for integration into low-voltage switchboards and control systems.
