Reliable 160A Thermal-Magnetic Circuit Protection
The ABB EPX-XT2N-TM1604 provides overload and short-circuit protection through its specified thermal-magnetic adjustable trip arrangement. The thermal element responds to sustained overcurrent conditions, while the magnetic element provides protection against short-circuit faults.
The four-pole XT2N configuration supports suitable three-phase distribution systems where four-pole switching is required. Its specified 36 kA breaking capacity must be assessed against the prospective short-circuit current and operating voltage of the intended installation.
For effective protection, electrical designers should confirm conductor sizing, protection settings, coordination requirements and compatibility with the selected ABB Protecta Power assembly. Correct installation and commissioning are essential for dependable circuit protection.
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.
- Main and sub-distribution circuit protection.
- Building services electrical distribution systems.
- Installations requiring thermal-magnetic MCCB protection.
