1SDA104306R1 ABB Emax 2 E1.2N/E9 1250 Ekip Touch LSIG 4-Pole WMP

Why Choose the ABB 1SDA104306R1 Emax 2 E1.2N/E9 1250 Ekip Touch LSIG 4-Pole WMP?

The ABB 1SDA104306R1 is a SACE Emax 2 E1.2N/E9 air circuit breaker moving part rated at 1250 A. This four-pole withdrawable configuration combines the E1.2N/E9 breaker platform with an advanced Ekip Touch LSIG electronic trip unit for comprehensive protection of demanding low-voltage power distribution systems.

The Ekip Touch LSIG trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. Its touchscreen-based interface provides access to protection settings, measurements and operating information, supporting efficient commissioning and management of the electrical distribution system.

Configured as a withdrawable moving part (WMP), the 1SDA104306R1 is designed to interface with the appropriate Emax 2 fixed chassis. Its four-pole, 1250 A construction and E1.2N/E9 configuration make it suitable for power distribution systems requiring advanced LSIG protection together with the operational flexibility of withdrawable switchgear.

Advanced Ekip Touch LSIG Circuit Protection

The Ekip Touch LSIG release combines comprehensive circuit protection with ABB's touchscreen trip-unit platform. Long-time protection responds to sustained overload conditions, short-time protection provides controlled response to high fault currents, instantaneous protection operates rapidly for severe short circuits, and the G function provides dedicated earth-fault protection.

In addition to protection, the Ekip Touch platform provides measurement and operating information through its digital interface and can form part of a wider connected Emax 2 system using compatible ABB accessories. Combined with the E1.2N/E9 1250 A four-pole withdrawable breaker architecture, this makes the 1SDA104306R1 suitable for critical distribution applications where protection performance, visibility and serviceability are important.
