Why Choose the ABB XT2S 125 TMF 15-400 3p F F UL/CSA?
The ABB XT2S 125 TMF 15-400 3p F F UL/CSA, order code 1SDA074772R1, is specified as a three-pole moulded case circuit breaker (MCCB) for low-voltage power distribution applications. Part of the ABB SACE Tmax XT2 range, the supplied specification identifies a 125 A frame with a 15 A TMF thermomagnetic trip unit.
The TMF thermomagnetic release combines thermal overload protection with magnetic short-circuit protection. In the supplied 15-400 configuration, the breaker has a 15 A rated current and 400 A magnetic trip threshold, providing straightforward circuit protection without requiring an electronic trip unit.
Configured as a three-pole fixed circuit breaker with front terminals, this XT2S variant is intended for integration into switchboards, distribution panels, machinery and OEM electrical assemblies. The S performance level is associated with the XT2S platform's enhanced interruption capability, while the UL/CSA designation identifies the configuration for applicable North American installations.

Reliable Thermomagnetic Protection for Low-Voltage Circuits
Thermomagnetic moulded case circuit breakers combine two established protection principles in a single device. The thermal element responds to sustained overload conditions, while the magnetic element provides rapid operation during high-current short circuits. This combination delivers dependable circuit protection without the configuration requirements associated with electronic trip units.
The ABB XT2S 125 configuration combines this proven protection principle with the compact Tmax XT2 platform. With the supplied 15 A TMF rating, 400 A magnetic threshold, three-pole construction and fixed front-terminal arrangement, it is suited to low-current three-phase circuits requiring robust overload and short-circuit protection.
Typical Applications
- Industrial low-voltage power distribution systems.
- Commercial switchboards and distribution panels.
- Three-phase feeder and branch-circuit protection.
- Machinery and industrial automation power supplies.
- Low-current circuits requiring MCCB protection.
- OEM electrical equipment for applicable North American markets.
- Control panels requiring UL/CSA-configured circuit protection.
