Why Choose the ABB TMG 630-3150 XT5 3p Trip Unit?
The ABB TMG 630-3150 XT5 3p, order code 1SDA100631R1, is a three-pole thermomagnetic trip unit for generator protection designed for the ABB SACE Tmax XT5 moulded case circuit breaker platform. Rated at 630 A, it provides thermal overload and magnetic short-circuit protection for compatible XT5 circuit breaker assemblies.
The TMG release is engineered specifically for generator protection, where protection characteristics need to accommodate the operating behaviour and fault-current characteristics of generating equipment. Its thermal element is adjustable from 0.7–1 × In, while its magnetic element is adjustable from 5–10 × In.
The 1SDA100631R1 is supplied as a three-pole protection release for use with a compatible three-pole ABB XT5 breaking part. This modular arrangement allows the breaking-capacity class and generator-protection release to be selected independently to suit the requirements of the low-voltage installation.

Thermomagnetic Protection for ABB Tmax XT5 Generator Applications
The ABB TMG release provides protection characteristics specifically intended for generator applications. Its adjustable thermal element protects against sustained overload conditions, while the magnetic element provides rapid short-circuit protection. With a rated current of 630 A, the 1SDA100631R1 is the highest-current TMG option in the three-pole XT5 generator-protection range.
As part of ABB's modular SACE Tmax XT5 architecture, the TMG release is used together with a compatible XT5 breaking part. This allows the interruption-performance class of the circuit breaker and the generator-protection characteristics of the release to be selected according to the electrical system requirements.
Typical Applications
- Low-voltage generator protection.
- Standby and emergency generator systems.
- Generator distribution switchboards.
- Industrial generating systems.
- Commercial and infrastructure standby-power installations.
- Generator feeders requiring thermal and magnetic protection.
- Three-phase low-voltage power distribution.
- Configurable ABB XT5 moulded case circuit breaker assemblies.
