1SDX253980R1 ABB EPX-XT2N-E1-1003 100A 3P 36kA MCCB Ekip LS/I

Why Choose the ABB EPX-XT2N-E1-1003 Protecta Power Circuit Breaker?

The ABB EPX-XT2N-E1-1003 is a high-performance 100 A three-pole moulded case circuit breaker (MCCB) designed to provide dependable overload and short-circuit protection in commercial and industrial low-voltage electrical distribution systems. Part of the ABB Protecta Power Devices range, this circuit breaker incorporates the ABB SACE Tmax XT2N160 platform with an Ekip LS/I electronic trip unit, delivering configurable protection for three-phase electrical installations.

Featuring a 36 kA short-circuit breaking capacity at 415 V AC, the EPX-XT2N-E1-1003 is designed to interrupt electrical faults while helping protect cables, switchgear and connected equipment. Its electronic trip unit provides long-time overload protection (L) together with selectable short-time delayed (S) or instantaneous (I) short-circuit protection, supporting effective protective device coordination.

With a 100 A rated current, three-pole configuration and compact 100 mm nominal width, this MCCB is suitable for outgoing feeders, commercial distribution boards and industrial switchboards. Its established ABB Tmax XT2N construction and compatibility with appropriately configured ABB Protecta Power distribution assemblies make it a practical choice for electrical contractors, panel builders and maintenance engineers.

Advanced Ekip LS/I Electronic Protection for Three-Phase Distribution

The ABB EPX-XT2N-E1-1003 incorporates an Ekip LS/I electronic trip unit designed to protect electrical installations against overloads and short-circuit faults. Electronic protection technology uses current sensing and electronic processing to deliver defined protective characteristics, helping engineers coordinate protective devices throughout low-voltage distribution systems.

The L (long-time) protection function responds to sustained excessive current, helping prevent overheating of electrical conductors and connected equipment. The S/I protection arrangement provides a choice between short-time delayed short-circuit protection and instantaneous short-circuit protection. Short-time delay can support selectivity with downstream devices, while instantaneous protection enables rapid interruption of high fault currents.

The ABB SACE Tmax XT2N160 platform combines electronic protection with robust moulded case construction. Its three-pole configuration enables simultaneous switching of three phase conductors, making it suitable for appropriately designed commercial and industrial three-phase electrical distribution circuits.

When installing the EPX-XT2N-E1-1003 within an ABB Protecta Power distribution board, appropriate mounting components, terminal connections and protective covers must be selected. Electrical designers should verify the prospective short-circuit current, conductor ratings, electronic trip settings and protective device coordination before commissioning.
