Reliable 25A Thermal-Magnetic Protection for Three-Phase Circuits
The ABB EPX-XT4N-TM0253 combines a 25 A rated current with a 36 kA specified breaking capacity, providing a circuit protection option for appropriately designed low-voltage distribution systems. Its thermal-magnetic adjustable protection arrangement responds to both sustained overloads and short-circuit faults.
The thermal protection element responds to excessive current sustained over time, while the magnetic protection element provides a response to short-circuit conditions. These complementary functions help protect electrical conductors and connected equipment when the MCCB is correctly selected, installed and coordinated with other protective devices.
The three-pole XT4N configuration supports suitable three-phase electrical distribution applications. Electrical designers should confirm the operating voltage, prospective short-circuit current, conductor sizing, protective settings and compatibility with the selected ABB Protecta Power assembly before installation.
Typical Applications
- ABB Protecta Power low-voltage distribution assemblies.
- 25 A three-pole outgoing circuit protection.
- Commercial three-phase electrical distribution boards.
- Industrial electrical panelboard installations.
- Three-phase equipment feeder protection.
- Building services electrical distribution systems.
- Circuits requiring thermal-magnetic MCCB protection.
- Installations requiring an appropriately rated 36 kA circuit breaker.
- Electrical distribution upgrades and refurbishment projects.
