Why Choose the ABB XT3N 225 TMF 1SDA075109R1 Circuit Breaker?
The ABB XT3N 225 TMF 1SDA075109R1 is a robust three-pole moulded case circuit breaker (MCCB) designed for low-voltage power distribution and equipment protection in UL/CSA applications. Part of the ABB SACE Tmax XT3 range, it combines a 225 A frame with a 60 A TMF thermomagnetic trip unit.
The TMF release provides thermal overload protection together with instantaneous magnetic short-circuit protection. This model has a rated trip-unit current of 60 A and an instantaneous short-circuit current setting of 600 A, delivering straightforward protection without electronic trip-unit programming.
The 1SDA075109R1 is a fixed, three-pole breaker with front bolt terminals and N-level short-circuit performance. Under UL 489 it provides interrupting ratings of 50 kA at 240 V AC, 25 kA at 480 V AC and 10 kA at 600Y/347 V AC, making it suitable for industrial, commercial and OEM distribution systems.
Key Advantages
- Proven ABB SACE Tmax XT3N moulded case circuit breaker platform.
- 60 A TMF thermomagnetic trip unit for overload and short-circuit protection.
- 600 A instantaneous magnetic setting for rapid response to severe fault currents.
- 25 kA UL 489 interrupting rating at 480 V AC.
- Three-pole configuration for three-phase power distribution circuits.
- Fixed mounting with front bolt terminals for practical switchboard and panel integration.
Key Features

- N short-circuit performance level.
- 50 kA interrupting rating at 240 V AC.
- 25 kA interrupting rating at 480 V AC.
- 10 kA interrupting rating at 600Y/347 V AC.
- Rated operational voltage of 600Y/347 V AC / 500 V DC.
- Fixed construction with front bolt terminals.
- UL 489 circuit breaker configuration.
TMF Thermomagnetic Circuit Protection
The TMF trip unit combines thermal overload protection and instantaneous magnetic short-circuit protection in a self-contained mechanical release. On the 1SDA075109R1, the trip unit has a rated current of 60 A and an instantaneous short-circuit setting of 600 A. This provides straightforward circuit protection without the configuration or auxiliary power requirements associated with more advanced electronic trip units.
The XT3N designation identifies the N-performance version of the XT3 frame. Under UL 489, this breaker provides 25 kA interruption capability at 480 V AC, with additional ratings of 50 kA at 240 V AC and 10 kA at 600Y/347 V AC. Its 225 A frame and 60 A trip unit should be distinguished: the frame defines the breaker platform's rated uninterrupted current, while the TMF release determines the protected circuit's 60 A trip rating.
Typical Applications
- Industrial low-voltage power distribution systems.
- Commercial electrical distribution panels.
- Three-phase feeder and branch circuit protection.
- Cable and equipment protection.
- Industrial machinery and plant electrical systems.
- UL/CSA switchboards and control panels.
- AC and suitable DC distribution circuits.
- OEM electrical equipment and panel-building applications.
