Reliable 800A Electronic Circuit Protection with ABB Tmax XT6 Technology
High-capacity electrical distribution systems require protective devices capable of responding to abnormal operating conditions while supporting effective coordination between incoming and outgoing circuits. Electronic moulded case circuit breakers provide adjustable protection characteristics that allow engineers to configure overload and short-circuit responses according to the requirements of the installation.
The ABB EPX-8004-E1-MCCB combines an 800 A Tmax XT6 circuit breaker with an Ekip LS/I electronic trip unit. Its long-time protection function responds to sustained overload conditions, helping protect electrical conductors and connected equipment against excessive thermal stress.
The LS/I configuration also provides a selectable short-circuit protection function. Short-time protection introduces a controlled delay where appropriate, while instantaneous protection provides a rapid response to high fault currents. The selected settings must be coordinated with the electrical installation's prospective fault current, downstream protective devices and conductor protection requirements.
The four-pole arrangement enables coordinated switching of three phase conductors and a neutral pole in suitable three-phase, four-wire distribution systems. Neutral protection settings and switching requirements must be established according to the specific breaker configuration, earthing arrangement and applicable electrical installation standards.
Within the ABB Protecta Power system, the EPX-8004-E1-MCCB is designated as an incoming circuit breaker for compatible 800 A distribution panelboards. ABB identifies the EPX-8004CK as the corresponding 800 A four-pole XT6 incoming connection kit. This separately specified kit provides the incoming support bracket, shrouding and busbar connection components required for the designated assembly arrangement.
ABB's Protecta Power documentation specifies a maximum XT6 incoming cable connection capacity of 2 × 120 mm², subject to the applicable terminal configuration. Front extended terminals are also available for suitable lug connections. The permissible conductor arrangement must be confirmed against the selected terminals, cable type and installation requirements.
Before commissioning, the completed assembly must be assessed for operating voltage, prospective short-circuit current, breaking capacity, conductor sizing, thermal performance and protective device coordination. The correct Ekip trip settings and neutral protection arrangements must be established using the applicable ABB technical documentation.
