1SDA071505R1 ABB E1.2C 1600 Ekip Touch LSI 4p F F Air Circuit Breaker 1600 A

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

The ABB E1.2C 1600 Ekip Touch LSI 4p F F, order code 1SDA071505R1, 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 LSI 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 LSI electronic protection release, providing long-time overload, selective short-time short-circuit and instantaneous short-circuit protection. The addition of the selective short-time function enables improved coordination with downstream protective devices, while the Ekip Touch colour display provides an intuitive interface for configuring and monitoring the protection unit.

With a rated uninterrupted current of 1600 A, a rated voltage of 690 V AC, an ultimate short-circuit breaking capacity of 50 kA at 400–440 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 makes it suitable for permanent switchboard installation.

Selective LSI Protection for High-Current Distribution

The ABB SACE Emax 2 E1.2C combines a compact air circuit breaker platform with substantial current capacity and short-circuit performance. Its 1600 A rating, 50 kA ultimate breaking capacity at 400–440 V AC and 42 kA short-time withstand capability for 1 s make it suitable for main incomers, distribution feeders and other high-current circuits where dependable fault interruption and selective coordination are important.

The Ekip Touch LSI trip unit combines three complementary protection functions. Long-time overload protection is adjustable from 640–1600 A, short-time delayed protection from 960–16000 A, and instantaneous protection from 2400–24000 A. This flexibility enables the breaker to be coordinated with other protective devices so that faults can be isolated selectively while helping maintain continuity of supply elsewhere in the distribution system.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial electrical distribution systems.
• Commercial building power distribution.
• Manufacturing and process plants.
• Main incomer and feeder circuit protection.
• Transformer secondary distribution systems.
• Distribution systems requiring selective short-circuit protection.
• High-current circuits requiring configurable electronic protection.
