Why Choose the ABB XT3N 225 TMF 150-1500 4P Circuit Breaker?
The ABB XT3N 225 TMF 150-1500 4P, order code 1SDA075155R1, is a fixed moulded case circuit breaker (MCCB) designed for reliable protection and isolation of low-voltage electrical distribution circuits. As part of the ABB Tmax XT range, it combines a compact XT3 frame with a thermomagnetic TMF trip unit for dependable overload and short-circuit protection.
This circuit breaker uses a TMF thermomagnetic trip unit with a 150 A current rating and 1500 A magnetic trip level. Its four-pole configuration allows simultaneous switching and protection of three phases and neutral, making it suitable for industrial and commercial distribution systems requiring four-pole circuit protection.
The XT3N 225 is supplied in a fixed configuration with front terminals and is specified for UL/CSA applications. Its 225 A frame size provides a robust platform for power distribution installations while the Tmax XT construction supports straightforward integration into switchboards, control panels and distribution assemblies.

Reliable Circuit Protection for Power Distribution
Moulded case circuit breakers such as the ABB XT3N protect electrical distribution systems against overloads and short circuits by automatically interrupting current when abnormal operating conditions occur. Thermomagnetic protection combines a thermal element for sustained overload protection with a magnetic element for rapid interruption during high-current faults.
The four-pole XT3N configuration enables all live conductors, including the neutral where required, to be switched together. Its fixed construction and front-terminal arrangement make it well suited to permanent installation in low-voltage switchboards, industrial panels and distribution assemblies.
Typical Applications
- Industrial low-voltage distribution boards.
- Commercial electrical distribution systems.
- Machine and production-line power distribution.
- Switchboards and electrical control panels.
- Three-phase systems requiring switched neutral protection.
- UL/CSA-oriented panel and equipment installations.
