Why Choose the ABB 1SDA074659R1 XT1N 125 TMF 80-800 4-Pole Circuit Breaker?
The ABB 1SDA074659R1, designated XT1N 125 TMF 80-800 4p F F UL/CSA, is a fixed four-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range. Built on the compact XT1N 125 frame, it has a rated current of 80 A and uses a TMF thermal-magnetic release for dependable overload and short-circuit protection.
Designed for UL/CSA applications, the XT1N combines thermal overload protection with instantaneous magnetic short-circuit protection. The TMF 80-800 configuration provides an 80 A thermal rating and an 800 A instantaneous magnetic trip threshold, providing straightforward circuit protection without an electronically powered trip unit.
The 1SDA074659R1 is supplied in a fixed configuration with front terminals and four poles. ABB specifies a rated voltage of 600Y/347 V AC and UL 489 interrupting ratings including 25 kA at 480 V AC, making this compact breaker suitable for industrial, commercial and OEM low-voltage distribution equipment.

Reliable Thermal-Magnetic Protection for UL/CSA Distribution Systems
The TMF trip unit combines thermal and magnetic operating principles within the circuit breaker. The thermal element responds to sustained overload currents that could overheat conductors and connected equipment, while the magnetic element provides rapid tripping when a severe short-circuit current reaches the instantaneous threshold.
For the ABB 1SDA074659R1, the protection is configured around an 80 A thermal rating and 800 A magnetic threshold. Combined with the XT1N interruption performance and four-pole construction, this provides compact and dependable protection for compatible industrial, commercial and OEM power distribution applications.
Typical Applications
- Industrial low-voltage distribution panels.
- Commercial building electrical distribution systems.
- Four-pole three-phase distribution circuits.
- OEM machinery and electrical equipment.
- Feeder and branch-circuit protection.
- Control panels and power distribution enclosures.
- UL/CSA-oriented electrical assemblies requiring compact thermal-magnetic protection.
