Why Choose the ABB TMG 320-1600 XT5 4-Pole Generator Protection Release?
The ABB TMG 320-1600 XT5 4p InN=100%In is a thermomagnetic protection release designed for ABB Tmax XT5 moulded-case circuit breakers used in generator protection applications. Identified by ABB order code 1SDA100695R1, this four-pole release combines thermal overload protection with magnetic short-circuit protection for dependable low-voltage generator circuits.
As part of the ABB Tmax XT5 circuit-breaker platform, the TMG release is specifically intended for generator protection. It has a rated current of 320 A and an instantaneous magnetic protection range of 800–1600 A, providing a magnetic threshold suited to the particular protection requirements associated with generating equipment.
The four-pole configuration incorporates a fully rated neutral, with InN = 100% In, allowing the neutral pole to carry and be protected at the same rated current as the phase poles. The release is designed for use with a compatible ABB Tmax XT5 breaking part to create a complete generator-protection circuit-breaker assembly.

Reliable Thermomagnetic Protection for Generators
Generator circuits require protection characteristics that account for the operating behaviour and available short-circuit current of generating equipment. The ABB TMG release combines thermal overload protection with magnetic short-circuit protection, helping protect generators, conductors and associated distribution equipment against damaging overcurrent conditions.
The TMG 320-1600 release is engineered for the ABB Tmax XT5 platform and provides a magnetic protection range of 800–1600 A. Its four-pole design with a fully rated neutral makes it suitable for generator distribution systems where protection and switching of all phase conductors and the neutral are required.
Typical Applications
- Low-voltage generator protection systems.
- Standby and emergency generating sets.
- Industrial generator distribution switchboards.
- Commercial building standby power systems.
- Generator-fed main and sub-main distribution circuits.
- Four-pole generator circuits requiring a fully rated neutral.
