Why Choose the ABB XT7H M 1250 Ekip Touch LSIG 1SDA101728R1 Circuit Breaker?
The ABB 1SDA101728R1 is a high-performance SACE Tmax XT7H M moulded-case circuit breaker (MCCB) designed for dependable protection and switching in demanding low-voltage electrical distribution systems. Rated at 1250 A, this four-pole circuit breaker combines ABB's XT7 M platform with an advanced Ekip Touch LSIG electronic trip unit for comprehensive protection of electrical installations.
The Ekip Touch LSIG release provides adjustable long-time, short-time, instantaneous and earth-fault protection, enabling the breaker to protect distribution systems against overloads, short circuits and earth faults. Its touchscreen-based electronic protection platform supports accurate configuration and monitoring while helping engineers achieve selective and coordinated protection across complex electrical networks.
This XT7H M configuration features a 1250 A rated current, four-pole construction, fixed installation and front terminals. The H breaking-capacity version provides an ultimate short-circuit breaking capacity of 70 kA at 380/415 V AC, making it suitable for industrial switchboards and distribution systems with high prospective fault currents.

Advanced Protection for Low-Voltage Power Distribution
Moulded-case circuit breakers such as the ABB Tmax XT7 protect electrical distribution systems by automatically interrupting current when abnormal conditions occur. The 1SDA101728R1 combines a high-current XT7H M power circuit breaker platform with ABB's electronic Ekip Touch protection technology, allowing protection parameters to be configured for the requirements of the installation.
The LSIG protection functions provide comprehensive coverage for overload, delayed short-circuit, instantaneous short-circuit and earth-fault conditions. This makes the breaker particularly suitable for main and feeder protection in industrial switchboards, commercial power distribution equipment and other installations where high fault-breaking performance and configurable protection are required.
Typical Applications
- Main low-voltage electrical distribution switchboards.
- Industrial power distribution systems.
- Commercial and infrastructure electrical installations.
- High-current feeder protection.
- Transformer secondary distribution systems.
- Motor control centres and industrial switchgear.
- Power distribution systems requiring earth-fault protection.
- OEM switchboards and electrical panel assemblies.
