Why Choose the ABB EPX-4004-E2-MCCB 400A 4-Pole Electronic LSI MCCB?
The ABB EPX-4004-E2-MCCB, manufacturer order code 1TVS151800S3615, is a 400 A, four-pole electronic moulded case circuit breaker (MCCB) based on the ABB Tmax XT5 platform. Designed for compatible ABB Protecta Power low-voltage electrical distribution panelboards, this incoming protective device combines high-current switching capability with electronic overload and short-circuit protection.
Featuring ABB Ekip LSI electronic trip protection, the EPX-4004-E2-MCCB provides adjustable long-time overload protection, short-time delayed short-circuit protection and instantaneous short-circuit protection. Unlike the LS/I arrangement, which requires selection between short-time and instantaneous protection characteristics, the LSI configuration provides all three L, S and I functions for protection adjustment.
Its 400 A current rating and four-pole configuration make the EPX-4004-E2-MCCB suitable for appropriately designed three-phase electrical distribution systems requiring electronic incoming circuit protection. As part of ABB's Protecta Power Enclosures product group, it supports coordinated panelboard construction using compatible incoming connection kits, busbar arrangements and electrical distribution accessories.

Understanding ABB Ekip LSI Electronic Protection
The ABB EPX-4004-E2-MCCB uses electronic LSI protection to provide configurable overcurrent protection for incoming electrical distribution circuits. This arrangement is particularly relevant where the incoming circuit breaker must coordinate with downstream protective devices while providing appropriate protection against overloads and short circuits.
The LSI protection configuration incorporates three distinct functions:
- L – Long-time overload protection: Protects conductors and connected equipment against sustained overcurrent conditions. The overload setting is selected according to the circuit design, conductor capacity and applicable protection requirements.
- S – Short-time delayed short-circuit protection: Provides a configurable short-time protection characteristic. Where correctly coordinated, this can allow downstream protective devices to operate before the incoming circuit breaker for certain fault conditions.
- I – Instantaneous short-circuit protection: Provides rapid tripping when the instantaneous short-circuit threshold is reached, helping limit the duration of high-current fault conditions.
The principal distinction between Ekip LS/I and Ekip LSI is the availability of the short-circuit protection functions. LS/I provides overload protection with a choice between S and I protection, whereas LSI incorporates L, S and I together for adjustment.
This additional flexibility can be valuable in electrical distribution systems requiring selective coordination between incoming and outgoing circuit breakers. However, selectivity is not guaranteed simply by selecting an LSI device. It must be verified using the applicable ABB coordination information, prospective fault levels and final protection settings.
The precise adjustment ranges and characteristics depend on the fitted electronic trip unit. These should be confirmed from the technical documentation for the supplied EPX-4004-E2-MCCB before commissioning.
Integration with ABB Protecta Power Panelboards
The ABB Protecta Power system provides a coordinated range of low-voltage distribution panelboards, incoming protective devices, outgoing MCCBs and connection accessories. The EPX-4004-E2-MCCB is intended for compatible configurations requiring a 400 A, four-pole electronic LSI incoming circuit breaker.
The associated EPX-4004CK is the ABB Protecta Power 400 A XT5 four-pole incoming connection kit. Incoming connection kit arrangements are designed to provide the necessary mechanical support, shrouding and electrical connections between the incoming device and the designated panelboard busbar system.
The incoming connection kit should be selected separately according to the complete distribution board configuration. The MCCB order code identifies the circuit breaker product and should not be assumed to include every component required for installation.
ABB's Protecta Power guidance identifies a maximum XT5 cable capacity of 185 mm². Actual conductor compatibility depends on the fitted terminals, conductor type, cable preparation and applicable installation requirements. Suitable front extended terminals may also be available for particular cable lug arrangements.
The four-pole design provides a configuration for electrical installations requiring four-pole incoming switching and protection. The exact neutral-pole protection characteristics must be confirmed from the supplied device and its electronic trip unit documentation.
Before final specification, the electrical designer should verify the required breaking capacity, rated operational voltage, prospective short-circuit current, conductor sizing, protection settings and compatibility with the selected Protecta Power enclosure. The 400 A rating and XT5 designation alone do not establish all these parameters.
ABB XT5 LS/I vs LSI Electronic MCCBs
ABB offers different electronic protection configurations within its Protecta Power incoming MCCB range. The EPX-4004-E2-MCCB is specifically identified as the 400 A, four-pole electronic LSI version.
- EPX-4004-E1-MCCB: 400 A, four-pole XT5 electronic MCCB with LS/I protection.
- EPX-4004-E2-MCCB: 400 A, four-pole XT5 electronic MCCB with LSI protection.
- EPX-4004MCCB: 400 A, four-pole XT5 thermal-magnetic MCCB.
The E2 LSI version is suited to applications requiring the availability of long-time, short-time and instantaneous electronic protection characteristics. The E1 LS/I version offers overload protection with selectable short-circuit characteristics, while the thermal-magnetic version uses a different trip technology.
Choosing the appropriate device requires consideration of the electrical system design, protective device coordination, available fault current and compatibility with the completed distribution assembly.
