Reliable Thermal-Magnetic Protection for Three-Phase Circuits
The ABB EPX-XT1N-TM0163 uses thermal-magnetic circuit protection technology to safeguard electrical installations against overloads and short circuits. The thermal element responds to sustained excessive current, helping prevent overheating of electrical conductors and connected equipment. The magnetic element responds rapidly to high short-circuit currents, disconnecting the affected circuit to limit potential damage.
The ABB SACE Tmax XT1N circuit breaker platform provides compact protection for low-voltage power distribution systems. Its three-pole construction allows simultaneous switching of three phase conductors, making it suitable for three-phase outgoing feeders and other compatible electrical distribution applications.
The EPX-XT1N-TM0163 is designed for integration into ABB Protecta Power distribution boards using suitable mounting and connection accessories. For Protecta Power outgoing MCCB installations, the compatible EPX-BPCXT1-3P base plate and cover should be selected separately where required. Correct cable sizing, prospective fault-current assessment and protective device coordination remain essential for safe installation.
