Horizontal Tmax XT3 Plug-In Circuit Breaker Integration
The ABB PHBX3427 installation kit is designed to support the integration of compatible Tmax XT3 3-pole and 4-pole plug-in circuit breakers within the System Pro E Power switchboard platform. Its specified horizontal installation arrangement provides a dedicated mounting configuration for electrical distribution assemblies using plug-in MCCB equipment.
A plug-in circuit breaker arrangement uses a compatible plug-in connection system to interface the circuit breaker with the electrical distribution assembly. This differs from a fixed circuit breaker installation, where the breaker is connected directly in its designated mounting position. The correct plug-in base, electrical connections and associated accessories must be selected for the specific Tmax XT3 configuration.
The PHBX3427 is specified for a 400 mm nominal switchboard width. This dimension identifies the intended System Pro E Power enclosure configuration rather than the independently verified physical width of the installation kit. Compatibility also depends on the internal mounting structure, selected circuit breaker version and associated ABB components.
The manufacturer designation includes RHD. Because the supplied abbreviated description does not independently define this term, it should be treated as a specific ABB installation-configuration identifier rather than assumed to describe a particular operating mechanism or door-hinge direction. The required RHD arrangement should be confirmed against the applicable ABB System Pro E Power assembly documentation.
The kit supports the designated 3-pole and 4-pole Tmax XT3 configurations. However, it should not be assumed to fit other Tmax circuit breaker frame sizes, such as XT2, XT4 or XT5, without explicit manufacturer confirmation. Different breaker families may require different mechanical mounting and connection accessories.
The ABB PHBX3427 is an installation accessory rather than a complete circuit breaker assembly. The Tmax XT3 circuit breaker, plug-in connection components, protective trip unit and any additional electrical accessories must be selected according to the intended installation. The product designation does not establish that these components are included in the kit.
The completed switchboard's electrical performance depends on the selected circuit breaker, its protection settings, conductors, connections and overall assembly design. The mechanical installation kit itself does not establish an independent current rating, breaking capacity or short-circuit withstand rating.
For professional electrical panel builders, the PHBX3427 offers a dedicated ABB mounting solution for the specified horizontal, plug-in XT3 arrangement, supporting consistent component selection and coordinated switchboard construction.

Frequently Asked Questions
What is the ABB PHBX3427 used for?
The ABB PHBX3427 is an installation kit designed for compatible 3-pole or 4-pole ABB Tmax XT3 plug-in circuit breakers in a horizontal mounting arrangement within a 400 mm nominal-width System Pro E Power switchboard configuration.
What is the ABB manufacturer order code for PHBX3427?
The official ABB manufacturer order code is 1STQ007815A0000, corresponding to the PHBX3427 installation kit.
Which circuit breaker series is compatible with the PHBX3427?
The kit is specifically designated for the ABB Tmax XT3 moulded case circuit breaker series. Compatibility with other Tmax frame sizes should not be assumed.
Does the PHBX3427 support both 3-pole and 4-pole circuit breakers?
Yes. The manufacturer designation 3-4P identifies compatibility with the specified 3-pole and 4-pole Tmax XT3 plug-in configurations.
Is the ABB PHBX3427 designed for fixed or plug-in circuit breakers?
The PHBX3427 is specifically identified for plug-in Tmax XT3 circuit breaker installations. It should not be assumed to support fixed or withdrawable versions without manufacturer confirmation.
What does RHD mean in the PHBX3427 product designation?
RHD is an ABB configuration identifier included in the manufacturer's description. Its exact application should be confirmed using the relevant System Pro E Power assembly documentation rather than inferred from the abbreviation alone.
What mounting orientation does the ABB PHBX3427 use?
The manufacturer designation specifies a horizontal installation arrangement. The kit should be selected for the designated horizontal configuration rather than assumed to support vertical mounting.
What switchboard width is associated with the PHBX3427?
The kit is specified for a 400 mm nominal switchboard width. This refers to the intended enclosure configuration rather than necessarily being the physical width of the installation kit itself.
Does the ABB PHBX3427 include the Tmax XT3 circuit breaker?
The PHBX3427 is identified as an installation kit rather than a complete circuit breaker assembly. The Tmax XT3 breaker, compatible plug-in components and other required electrical accessories should be selected separately unless explicitly included in the manufacturer's supplied kit contents.
Does the PHBX3427 have its own electrical current rating?
The supplied product designation does not specify an independent electrical current rating for the PHBX3427 mechanical installation kit. The applicable electrical ratings depend on the selected Tmax XT3 circuit breaker and the completed switchboard assembly.
