Why Choose the ABB XT5H 400 Ekip Dip LS/I 1SDA100527R1 Circuit Breaker?
The ABB 1SDA100527R1 is a high-performance SACE Tmax XT5H moulded-case circuit breaker (MCCB) designed for dependable protection and switching in demanding low-voltage AC power distribution systems. This fixed four-pole circuit breaker features front terminals and an Ekip Dip LS/I solid-state electronic trip unit, providing configurable overload and short-circuit protection.
As part of the ABB SACE Tmax XT series, the XT5H 400 combines compact construction with high short-circuit interruption capability and electronic protection. The Ekip Dip LS/I release provides Long-time (L) overload protection together with selectable Short-time (S) or Instantaneous (I) short-circuit protection, supporting effective coordination with feeders, cables and downstream protective devices.
The 1SDA100527R1 has a 320 A rated current on the XT5 400 A frame and a four-pole configuration. Its XT5H interruption class is designed for high prospective fault-current applications, while the fixed mounting arrangement and front terminals provide a practical configuration for industrial, commercial and infrastructure switchboards.

Advanced Electronic Protection for High-Fault-Level Distribution
The ABB Ekip Dip LS/I release provides electronic protection for applications requiring dependable overload and short-circuit response. Long-time protection monitors sustained overcurrent conditions, helping protect cables and distribution equipment against damaging overloads while providing greater adjustment flexibility than a conventional fixed protection arrangement.
The S/I short-circuit function allows the protection strategy to use Short-time or Instantaneous operation according to the coordination requirements of the installation. Combined with the XT5H platform's high interruption performance and the breaker's 320 A rated current, this makes the 1SDA100527R1 particularly suitable for high-fault-level industrial and commercial distribution systems.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-distribution switchboards.
- Transformer-fed electrical distribution.
- High-fault-level four-pole feeder protection.
- Manufacturing and process installations.
- Commercial building electrical distribution.
- Infrastructure and utility power distribution systems.
