Reliable 160A Thermal-Magnetic Circuit Protection
The ABB EPX-XT1N-TM1604 provides overload and short-circuit protection through its thermal-magnetic adjustable trip arrangement. The thermal protection element responds to sustained excessive current, while the magnetic element responds to short-circuit fault conditions.
Its four-pole XT1N configuration supports appropriately designed three-phase distribution systems where four-pole switching is required. The specified 36 kA breaking capacity must be assessed against the prospective fault current and operating voltage of the intended electrical installation.
For dependable protection, electrical designers should verify conductor sizing, protection settings, protective device coordination and compatibility with the selected ABB Protecta Power assembly. Correct installation and commissioning are essential to achieving the intended protective performance.
Typical Applications
- ABB Protecta Power low-voltage distribution assemblies.
- 160 A four-pole outgoing circuit protection.
- Commercial three-phase electrical distribution boards.
- Industrial electrical panelboards and switchgear assemblies.
- Main and sub-distribution circuit protection.
- Building services electrical distribution systems.
- Installations requiring thermal-magnetic MCCB protection.
