Information About XT5NU340ABYN000XXX
The XT5NU340ABYN000XXX belongs to ABB's SACE Tmax XT family of low-voltage circuit protection equipment. Its XT5N frame incorporates a thermal-magnetic adjustable trip mechanism for long-time overload and instantaneous short-circuit protection. The three-pole construction supports three-phase electrical distribution systems, while its fixed front-terminal configuration is intended for compatible ReliaGear neXT panelboard installations. The breaker accommodates load-side connections using two conductors sized from 2/0 AWG to 500 kcmil, supporting high-current power distribution applications.
Key Features:
-
Rated Current: Provides a nominal current rating of 400 A.
-
Three-Pole Configuration: Designed for three-phase electrical distribution systems.
-
Thermal-Magnetic Protection: Uses an adjustable TMA trip unit for overload and short-circuit protection.
-
Interrupting Capacity: Provides a 25 kA interrupting rating at 480 VAC.
-
Voltage Rating: Supports electrical systems up to 600 VAC.
-
XT5N Frame: Uses ABB's SACE Tmax XT5N molded case breaker platform.
-
Panelboard Compatibility: Designed for compatible ABB ReliaGear neXT installations.
-
Load Connections: Supports two conductors sized 2/0 AWG to 500 kcmil.
The XT5NU340ABYN000XXX delivers the reliability and precision required for high-current electrical distribution, circuit protection, and industrial power panelboard applications.
