Why Choose the ABB XT5S 400 TMA 300-3000 4p FF InN100%In UL Circuit Breaker?
The ABB XT5S 400 TMA 300-3000 4p FF InN100%In UL, order code 1SDA102611R1, is a four-pole SACE Tmax XT5 moulded-case circuit breaker (MCCB) for low-voltage power distribution. It combines a 400 A frame with a 300 A TMA thermomagnetic trip unit, providing dependable overload and short-circuit protection for industrial and commercial electrical systems.
The TMA release provides an adjustable thermal overload setting from 210–300 A together with an adjustable instantaneous magnetic trip setting from 1500–3000 A. The four-pole configuration uses a neutral pole rated at 100% of the phase rating, making it suitable for systems where full neutral conductor protection and switching are required.
This XT5S circuit breaker is supplied in a fixed configuration with front terminals and is designed to UL 489. The S performance level is rated at 50 kA in the XT5 UL/CSA range, while the breaker is specified for operation up to 600 V AC and 600 V DC, providing a robust solution for demanding power-distribution installations.

Reliable Circuit Protection for Industrial Power Distribution
Thermomagnetic moulded-case circuit breakers provide coordinated protection against both sustained overloads and high-current short circuits without requiring a separate electronic trip unit. The adjustable thermal element of the TMA release allows the protection threshold to be matched to the connected circuit, while the magnetic element provides rapid operation during severe fault conditions.
With its 300 A TMA release, four-pole construction and 100% neutral rating, the ABB 1SDA102611R1 is particularly suited to three-phase, four-wire distribution systems requiring simultaneous switching and protection of the neutral conductor. Its XT5S platform provides the breaking performance required for demanding industrial and commercial switchboard applications.
Typical Applications
- Industrial low-voltage switchboards.
- Three-phase, four-wire power distribution systems.
- Commercial building distribution panels.
- Industrial feeder and sub-distribution protection.
- Manufacturing and process-industry electrical systems.
- UL 489 installations requiring adjustable 300 A thermomagnetic protection.
