Thermomagnetic Protection for Tmax T5 Generator Applications
A thermomagnetic trip unit combines thermal overload protection with magnetic short-circuit protection. The thermal element responds to sustained overcurrent conditions, while the magnetic element operates rapidly when current rises to a high fault level. This combination provides robust circuit protection using established electromechanical operating principles.
The ABB 1SDA055093R1 is a 320 A TMG release for compatible Tmax T5 circuit breakers, with its instantaneous short-circuit threshold adjustable from 800 A to 1600 A. The TMG range is intended for generator protection applications, making this release suitable for low-voltage generation and distribution systems requiring coordinated overload and short-circuit protection.
Typical Applications
- Generator protection systems.
- ABB SACE Tmax T5 moulded case circuit breakers.
- Three-phase low-voltage electrical systems.
