Why Choose the ABB TMA 630-6300 XT5 3p Trip Unit?
The ABB TMA 630-6300 XT5 3p is a three-pole thermomagnetic protection release designed for compatible ABB SACE Tmax XT5 moulded case circuit breakers. It provides thermal overload and magnetic short-circuit protection as part of a complete XT5 circuit-breaker assembly.
Designed for a rated current of 630 A, the TMA release combines dependable thermal protection with an adjustable instantaneous magnetic trip threshold. ABB specifies an instantaneous short-circuit setting range of 3150–6300 A, allowing the protection characteristics to be coordinated with the requirements of the protected circuit.
ABB order code 1SDA100577R1 is the three-pole TMA protection release for the XT5 platform and is intended to be used together with a compatible XT5 breaking part. Its thermomagnetic operating principle provides a straightforward protection solution for industrial and commercial low-voltage power-distribution applications.

Thermomagnetic Protection for ABB Tmax XT5 Circuit Breakers
The ABB TMA release combines two established protection principles within a compatible XT5 circuit-breaker assembly. The thermal element responds to sustained overload conditions, while the magnetic element provides rapid operation when severe short-circuit currents exceed the configured instantaneous threshold.
For the 1SDA100577R1, the 630 A TMA release provides an instantaneous short-circuit adjustment range of 3150–6300 A. The trip unit must be combined with an appropriate compatible XT5 breaking part to form the required complete circuit-breaker configuration.
Typical Applications
- ABB SACE Tmax XT5 circuit-breaker assemblies.
- Industrial low-voltage distribution switchboards.
- Main and sub-distribution feeder protection.
- Manufacturing and process-industry electrical systems.
- Commercial and infrastructure power distribution.
- Custom three-pole XT5 protection configurations.
