Why Choose the ABB TMA 320-3200 In=320A 3P XT5L 1SDA100574R1 Trip Unit?
The ABB TMA 320-3200 In=320A 3P XT5L 1SDA100574R1 is a thermal-magnetic trip unit designed for compatible ABB SACE Tmax XT5L moulded-case circuit breakers. With a rated current of 320 A and a three-pole configuration, this trip unit provides dependable overload and short-circuit protection for low-voltage power distribution applications.
The TMA thermal-magnetic release combines thermal overload protection with magnetic instantaneous short-circuit protection. The thermal element responds to sustained overcurrent conditions, while the magnetic element provides rapid operation when high fault currents occur, helping protect cables, busbars and connected electrical equipment.
Designed for the ABB SACE Tmax XT5L platform, the 1SDA100574R1 has a rated current of 320 A and an instantaneous magnetic trip setting of 3200 A. Supplied as the trip unit only, it is intended for use with the appropriate compatible XT5L circuit-breaker assembly rather than as a complete circuit breaker.

Reliable Thermal-Magnetic Protection for Tmax XT5L
Thermal-magnetic trip units provide two complementary forms of overcurrent protection. The thermal element responds to sustained overload currents that could otherwise cause excessive heating of conductors and equipment, while the magnetic element operates rapidly when a high short-circuit current exceeds its trip threshold.
The ABB TMA 320-3200 combines these protection principles in a dedicated trip unit for compatible Tmax XT5L circuit breakers. With a 320 A nominal rating and 3200 A magnetic trip setting, it provides straightforward circuit protection for three-phase distribution applications without the additional functionality of an electronic release.
Typical Applications
- ABB SACE Tmax XT5L circuit-breaker assemblies.
- Three-phase low-voltage power distribution systems.
- Industrial electrical switchboards.
- Feeder and distribution circuit protection.
- Commercial building electrical distribution.
- Manufacturing and process-industry installations.
- Applications requiring thermal overload and instantaneous short-circuit protection.
