Why Choose the ABB XT5S 400 TMA 320-3200 3P Circuit Breaker?
The ABB XT5S 400 TMA 320-3200 3P F F 1SDA100414R1 is a fixed three-pole SACE Tmax XT5 moulded case circuit breaker designed for dependable protection of low-voltage power-distribution systems. It combines an XT5S 400 frame with a 320 A TMA thermomagnetic release for overload and short-circuit protection.
The TMA thermomagnetic trip unit provides adjustable thermal overload protection together with adjustable instantaneous magnetic short-circuit protection. Its thermal setting range is 224–320 A, while the instantaneous magnetic release can be adjusted from 1600–3200 A, supporting effective coordination with cables and connected equipment.
The 1SDA100414R1 is supplied as a fixed three-pole breaker with front terminals. The XT5S performance class provides an ultimate short-circuit breaking capacity of 50 kA at 415 V AC, making this breaker suitable for industrial, commercial and infrastructure installations requiring higher fault-interruption capability.

Adjustable Thermomagnetic Protection with 50 kA Breaking Capacity
The ABB XT5S 400 uses a TMA thermomagnetic release to provide reliable circuit protection without requiring a solid-state electronic trip unit. The thermal element responds to sustained overloads and can be adjusted from 224–320 A, while the magnetic element provides rapid short-circuit protection with an adjustable threshold from 1600–3200 A.
With its 320 A rating, 50 kA ultimate breaking capacity at 415 V AC and fixed front-terminal construction, the 1SDA100414R1 is suited to feeder, transformer, generator and installation protection where robust fault interruption and adjustable thermomagnetic protection are required.
Typical Applications
- Industrial low-voltage distribution boards.
- Main and sub-main switchboards.
- Commercial building power distribution.
- Manufacturing and process installations.
- Three-phase feeder and cable protection.
- Transformer protection.
- Generator and installation protection.
- Circuits requiring higher short-circuit interruption capability.
