1SDA071504R1 ABB E1.2C 1600 Ekip Touch LI 4p F F Air Circuit Breaker 1600 A

Why Choose the ABB E1.2C 1600 Ekip Touch LI 4p F F Air Circuit Breaker?

The ABB E1.2C 1600 Ekip Touch LI 4p F F, order code 1SDA071504R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and switching in demanding low-voltage electrical distribution systems. Combining the compact E1.2 frame with the C performance level and an Ekip Touch LI electronic trip unit, it provides configurable protection for high-current industrial, commercial and infrastructure power networks.

This fixed circuit breaker features front terminals and an Ekip Touch LI electronic protection release, providing long-time overload and instantaneous short-circuit protection. The Ekip Touch interface enables convenient configuration and access to breaker information, making the unit suitable for applications requiring adjustable electronic protection without selective short-time or earth-fault functions.

With a rated uninterrupted current of 1600 A, an ultimate short-circuit breaking capacity of 50 kA at 440 V AC and a rated short-time withstand current of 42 kA for 1 s, the E1.2C 1600 is designed for substantial electrical loads and demanding fault conditions. Its four-pole configuration enables switching across three phases and neutral, while its fixed construction and front connections provide a practical arrangement for permanent switchboard installation.
