The ABB EPX-4003CK is a dedicated 400 A XT5 connection kit designed for three-pole circuit breaker installations within compatible ABB Protecta Power enclosure assemblies. Identified by ABB order code 1SKV280035S0001, this connection accessory supports the electrical integration of an ABB Tmax XT5 moulded case circuit breaker into an appropriately configured low-voltage distribution system.
As part of the ABB Protecta Power Enclosures product range, the EPX-4003CK provides a manufacturer-designated connection solution for applications using a 400 A, three-pole XT5 circuit breaker arrangement. It is intended to support the connection interface between the specified breaker configuration and the associated distribution assembly, subject to the relevant ABB installation requirements.
Designed for professional electrical panel builders, switchboard manufacturers and installation engineers, the EPX-4003CK helps simplify component identification when specifying connections for compatible ABB XT5 circuit breaker installations. Its defined 400 A application and 3P configuration make it suitable for projects requiring coordinated circuit breaker connection accessories within the Protecta Power enclosure system.
The ABB EPX-4003CK connection kit provides a dedicated accessory for integrating a compatible 400 A, three-pole ABB Tmax XT5 circuit breaker into an appropriately configured Protecta Power electrical distribution assembly. Correctly selected connection components are essential for establishing the intended electrical interface between the circuit breaker and the associated distribution conductors.
The kit is specified for a 400 A XT5 3P arrangement. This designation identifies its intended application but does not establish the complete distribution board's continuous current capacity, short-circuit withstand performance or operating temperature limits independently. These characteristics depend on the installed breaker, connection system, conductor arrangement, enclosure design and verification of the completed assembly.
During installation, electrical panel builders should confirm compatibility with the selected XT5 circuit breaker variant, its terminal configuration and the relevant ABB Protecta Power enclosure arrangement. The connection components must be installed in accordance with the applicable ABB instructions, including any specified fixing methods, tightening torques, electrical clearances and insulation requirements.
The EPX-4003CK is a connection accessory rather than a protective circuit breaker. Overload and short-circuit protection are provided by the appropriately selected XT5 breaker and its trip unit. The complete distribution assembly must be designed and verified for the intended electrical operating conditions, including temperature rise, short-circuit performance and protection against electric shock.

The ABB EPX-4003CK is a 400 A three-pole XT5 connection kit intended for compatible ABB Protecta Power electrical distribution assemblies. It supports the connection of an appropriately selected ABB Tmax XT5 circuit breaker within the specified enclosure arrangement.
The EPX-4003CK is designated for the ABB Tmax XT5 circuit breaker family, specifically a 400 A, three-pole connection arrangement. Compatibility with an individual XT5 breaker variant, mounting configuration and terminal arrangement should be confirmed against the relevant ABB installation documentation.
3P means three-pole. The EPX-4003CK is specified for a three-pole XT5 circuit breaker connection arrangement rather than a four-pole configuration.
The manufacturer designation identifies the EPX-4003CK as a connection kit, not a complete circuit breaker assembly. An XT5 circuit breaker is not identified as included in the supplied product description. The precise kit contents should be checked against ABB's applicable product documentation.
No. The EPX-4003CK is a circuit breaker connection accessory. Overload and short-circuit protection are functions of the correctly selected ABB XT5 circuit breaker and its associated trip unit. The complete electrical distribution assembly must also be designed and verified for its intended operating conditions.
ABB Protecta Power connection accessories support professional electrical panel builders, switchboard manufacturers and distribution engineers in developing coordinated low-voltage distribution assemblies using compatible ABB circuit breakers, enclosure components and connection arrangements.
