1SDA071435R1 ABB E1.2N 1000 Ekip Touch LSI 4-Pole Air Circuit Breaker

Why Choose the ABB 1SDA071435R1 E1.2N 1000 Ekip Touch LSI Air Circuit Breaker?

The ABB 1SDA071435R1 is a high-performance SACE Emax 2 E1.2N air circuit breaker designed for protection and switching in low-voltage power distribution systems. Rated at 1000 A, this four-pole fixed breaker combines ABB's compact E1.2N frame with the advanced Ekip Touch LSI electronic trip unit.

The Ekip Touch LSI release provides long-time overload (L), short-time selective short-circuit (S) and instantaneous short-circuit (I) protection. The addition of short-time protection enables improved selective coordination with other protective devices, while the touchscreen interface provides convenient access to protection settings and operating information.

The 1SDA071435R1 is supplied in a fixed four-pole configuration with front terminals. The E1.2N platform provides an ultimate short-circuit breaking capacity of 66 kA at 380–440 V AC and 50 kA at 500–690 V AC, together with a rated short-time withstand current of 50 kA for 1 s, making it suitable for demanding industrial and commercial distribution systems.
