Why Choose the ABB EPX-4004-E1-MCCB 400A 4-Pole Electronic MCCB?
The ABB EPX-4004-E1-MCCB, manufacturer order code 1TVS151800S3371, is a 400 A, four-pole electronic moulded case circuit breaker (MCCB) from the ABB Tmax XT5 family, specified as an incoming protective device for compatible ABB Protecta Power low-voltage distribution panelboards.
Featuring an ABB Ekip LS/I electronic trip unit, the EPX-4004-E1-MCCB provides overload protection and selectable short-circuit protection characteristics. Its four-pole configuration is intended for distribution arrangements requiring a four-pole incoming circuit breaker, subject to the applicable neutral protection and switching requirements.
Designed for integration into the Protecta Power system, this MCCB provides a manufacturer-designated incoming protection solution for commercial and industrial distribution installations. The product is part of ABB's coordinated range of incoming devices, connection kits and panelboard accessories, helping electrical contractors and switchboard builders specify compatible equipment for their distribution assemblies.

Ekip LS/I Electronic Protection for 400A Incoming Distribution Circuits
The ABB EPX-4004-E1-MCCB combines the Tmax XT5 circuit breaker platform with electronic trip protection for incoming distribution applications. Electronic protection enables settings to be selected according to the circuit characteristics and the coordination requirements of the electrical installation.
The standard Ekip LS/I trip arrangement provides L overload protection together with a choice between S short-circuit protection with delayed tripping and I instantaneous short-circuit protection. This differs from an Ekip LSI arrangement, in which all three L, S and I characteristics are available together for adjustment. Protection settings must be established through the electrical design and commissioning process.
The four-pole XT5 configuration is intended for suitable incoming arrangements in which four-pole switching or protection is required. The precise neutral-pole protection behaviour must be confirmed from the fitted circuit breaker and trip unit documentation rather than assumed solely from the 4P designation.
Integration with ABB Protecta Power Panelboards
ABB lists the EPX-4004-E1-MCCB as a 400 A, four-pole electronic XT5 incoming MCCB in its Protecta Power selection guide. The incoming device range also includes thermal-magnetic XT5 alternatives and three-pole electronic variants, enabling designers to select the appropriate protective technology and pole arrangement.
The associated EPX-4004CK is the manufacturer-designated 400 A XT5 four-pole incoming connection kit. ABB identifies incomer support brackets, shrouding and busbar connectivity within its incoming connection kit arrangements. The required connection kit and other installation components should be selected separately according to the complete panelboard configuration.
ABB lists a maximum XT5 cable capacity of 185 mm² in its Protecta Power incoming device guidance. Actual conductor compatibility depends on the fitted terminals, conductor material, cable preparation and installation requirements. Front extended terminals are also identified by ABB as an available option for suitable lug connections.
The specific breaking capacity, rated operational voltage and detailed trip adjustment ranges of the supplied EPX-4004-E1-MCCB should be verified against its exact ABB circuit breaker configuration before final specification. These values are not determined solely by the XT5 frame size and 400 A rating.
Typical Applications
- ABB Protecta Power 400 A incoming MCCB installations.
- Commercial building main and sub-main electrical distribution.
- Industrial low-voltage switchboards and panelboards.
- Three-phase electrical distribution systems requiring four-pole incoming protection.
- Electrical plant rooms and power distribution infrastructure.
- Building services distribution installations.
- Commercial facilities requiring electronic overcurrent protection.
- Electrical panel manufacturing and switchboard assembly.
- Distribution systems requiring coordinated overload and short-circuit protection.
- Compatible ABB Protecta Power panelboard upgrades and refurbishment projects.
