1SDA071466R1 ABB E1.2C 1250 Ekip Touch LSIG 4p F F Air Circuit Breaker 1250 A

Why Choose the ABB E1.2C 1250 Ekip Touch LSIG 4p F F Air Circuit Breaker?

The ABB E1.2C 1250 Ekip Touch LSIG 4p F F, order code 1SDA071466R1, 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 an Ekip Touch LSIG electronic trip unit, it provides comprehensive protection for industrial, commercial and infrastructure power networks.

This fixed circuit breaker features front terminals and an Ekip Touch LSIG electronic protection release, providing long-time overload, selective short-time short-circuit, instantaneous short-circuit and earth-fault protection. The Ekip Touch interface provides straightforward access to protection settings and operating information, while the LSIG functionality supports effective coordination across complex distribution networks.

With a rated uninterrupted current of 1250 A, a rated operational voltage of 690 V AC and the enhanced short-circuit performance of the E1.2C frame, the 1SDA071466R1 is suited to substantial electrical loads and critical distribution circuits. Its four-pole configuration enables switching across three phases and neutral, while its fixed construction and front terminal arrangement provide a practical solution for permanent switchboard installation.

Comprehensive LSIG Protection for High-Current Distribution

The ABB SACE Emax 2 E1.2C combines substantial current capacity with a compact air circuit breaker platform for demanding low-voltage distribution duties. With a rated uninterrupted current of 1250 A and rated operational voltage of 690 V AC, the breaker is suitable for main incomers, distribution feeders and other high-current circuits within industrial and commercial switchboards.

The Ekip Touch LSIG trip unit combines four key protection functions in one electronic release. Long-time protection responds to sustained overloads, selective short-time protection supports coordination during high-current faults, instantaneous protection provides rapid response to severe short circuits, and earth-fault protection addresses current flowing to earth. Together, these functions provide a flexible protection platform for sophisticated low-voltage distribution systems.

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.
• Installations requiring integrated earth-fault protection.
