1SDA071506R1 ABB Emax 2 E1.2C 1600A Ekip Touch LSIG 4P Air Circuit Breaker

Why Choose the ABB 1SDA071506R1 Emax 2 Air Circuit Breaker?

The ABB 1SDA071506R1 is a high-performance SACE Emax 2 E1.2C air circuit breaker (ACB) designed for advanced protection and control of low-voltage electrical distribution systems. Rated at 1600 A, this fixed four-pole circuit breaker combines ABB’s compact E1.2 frame with the Ekip Touch LSIG electronic trip unit for comprehensive overload, short-circuit and ground-fault protection.

As part of the ABB SACE Emax 2 series, the E1.2C is engineered to provide high short-circuit performance and effective selectivity within compact switchboard installations. The Ekip Touch LSIG release provides long-time, short-time, instantaneous and ground-fault protection, while its large colour touchscreen enables intuitive configuration and operation. Ekip Connect compatibility also allows programming and interrogation of the electronic trip unit from compatible devices.

With a rated uninterrupted current of 1600 A, rated operational voltage of 690 V AC, rated ultimate short-circuit breaking capacity of 50 kA at 400–440 V AC and rated short-time withstand current of 42 kA for 1 s, the 1SDA071506R1 provides robust protection for demanding low-voltage networks. This version features a fixed four-pole configuration with front terminals for efficient integration into industrial, commercial and infrastructure switchboards.
