Why Choose the ABB PHDX4401 XT4 Fixed Horizontal Installation Kit?
The ABB PHDX4401 XT4 Fixed Horizontal Installation Kit, manufacturer order code 1STQ001447B0000, is a dedicated circuit breaker installation accessory from the ABB System pro E power range. Designed for compatible low-voltage switchgear assemblies, this kit is specified for the horizontal installation of ABB Tmax XT4 moulded case circuit breakers in fixed configurations, accommodating 3-pole and 4-pole arrangements within a nominal 800 mm-wide switchboard section.
Correct circuit breaker installation is essential for the mechanical organisation, accessibility and maintainability of industrial electrical distribution equipment. The ABB PHDX4401 provides a configuration-specific installation kit for integrating compatible Tmax XT4 breakers into System pro E power switchboards, helping panel builders establish the intended fixed horizontal equipment arrangement.
The kit's designation identifies three important selection characteristics: XT4 compatibility, fixed horizontal installation and 800 mm enclosure width. These details help distinguish the PHDX4401 from installation accessories intended for other circuit breaker frame sizes, mounting orientations or switchboard configurations.
As an ABB System pro E power accessory, the PHDX4401 is relevant to industrial switchboard manufacturing, electrical distribution panel assembly and maintenance projects where a compatible Tmax XT4 circuit breaker must be installed in the specified arrangement. Its dedicated order code, 1STQ001447B0000, supports accurate product identification, procurement and replacement.

Reliable Fixed Horizontal Installation of ABB Tmax XT4 Circuit Breakers
Industrial low-voltage distribution switchboards require carefully planned circuit breaker mounting arrangements to accommodate protective devices, electrical connections and maintenance access. The installation method must correspond to the circuit breaker frame, pole configuration, enclosure dimensions and intended equipment layout.
The ABB PHDX4401 is specifically identified for fixed horizontal installation of compatible ABB Tmax XT4 moulded case circuit breakers. Its designation covers both 3-pole and 4-pole configurations, making it relevant to appropriately designed three-phase distribution applications, including arrangements requiring a fourth switched pole.
The fixed installation designation distinguishes this kit from arrangements intended for plug-in or withdrawable circuit breakers. A fixed-mounted breaker is installed as part of a defined switchboard assembly, and the mounting kit must be selected to match the particular equipment configuration. The PHDX4401 should not be assumed to support alternative mounting technologies without explicit manufacturer confirmation.
The horizontal installation designation identifies the intended mounting arrangement within the switchboard. The nominal 800 mm width relates to the specified System pro E power enclosure configuration and should not be interpreted as the physical width of the circuit breaker or the mounting kit itself.
The ABB Tmax XT4 family includes moulded case circuit breakers used for low-voltage electrical distribution and circuit protection. However, the PHDX4401 is a mechanical installation accessory, not a circuit breaker. It does not independently provide overload protection, short-circuit protection, switching or isolation. Electrical ratings, breaking capacities and trip-unit functions depend on the separately selected XT4 breaker.
The supplied product designation does not identify the exact kit contents, mounting hardware quantities, compatible XT4 subvariants, terminal arrangements or electrical connection accessories. These details should be established from the applicable ABB assembly documentation. Installation must also account for conductor routing, required clearances, thermal conditions and the complete switchboard design.
For reliable operation of the finished assembly, the PHDX4401 should be installed according to the relevant ABB System pro E power and Tmax XT4 instructions. Correct component selection and installation support consistent mechanical integration, maintainability and compliance with the intended switchboard configuration.

Frequently Asked Questions
What is the ABB PHDX4401 installation kit used for?
The ABB PHDX4401 is an installation kit for fixed horizontal mounting of compatible ABB Tmax XT4 moulded case circuit breakers within specified System pro E power switchboard configurations.
What is the ABB order code for the PHDX4401?
The manufacturer order code is 1STQ001447B0000, corresponding to the ABB PHDX4401 XT4 3-4P Fixed Horizontal Installation Kit for a nominal 800 mm-wide switchboard section.
Which circuit breaker series is compatible with the ABB PHDX4401?
The PHDX4401 is specifically designated for the ABB Tmax XT4 moulded case circuit breaker family. Compatibility with a particular XT4 model, terminal arrangement and installation configuration should be confirmed using the applicable ABB documentation.
Does the ABB PHDX4401 support both 3-pole and 4-pole breakers?
Yes. The manufacturer designation explicitly identifies 3-pole and 4-pole Tmax XT4 circuit breaker configurations. The installation must still match the selected breaker and the corresponding switchboard assembly arrangement.
What does fixed horizontal installation mean?
Fixed horizontal installation means the kit is intended for a fixed-mounted circuit breaker in the specified horizontal arrangement. It is not identified as a plug-in or withdrawable installation kit.
What switchboard width is the ABB PHDX4401 designed for?
The PHDX4401 is designated for a nominal switchboard section width of 800 mm. This identifies the corresponding enclosure configuration rather than the physical dimensions of the circuit breaker or installation kit.
Is the ABB PHDX4401 compatible with System pro E power switchboards?
Yes. The PHDX4401 belongs to the ABB System pro E power range. Its suitability for a particular enclosure frame and circuit breaker arrangement should be confirmed against the relevant ABB assembly instructions.
Does the ABB PHDX4401 include an XT4 circuit breaker?
The supplied product designation identifies the PHDX4401 as an XT4 installation kit, not a complete circuit breaker. It does not confirm that a breaker is included, so the circuit breaker and exact package contents should be verified separately.
Does the ABB PHDX4401 determine the circuit breaker's current rating or breaking capacity?
No. The PHDX4401 is a mechanical installation accessory. The rated current, breaking capacity and protective functions depend on the separately selected ABB Tmax XT4 circuit breaker and its trip unit.
Can ABB 1STQ001447B0000 be used as a replacement installation kit?
Yes, it may be selected as a replacement where the original switchboard specifies ABB PHDX4401 or order code 1STQ001447B0000. The replacement must match the XT4 breaker configuration, pole arrangement, fixed horizontal mounting requirements and nominal 800 mm enclosure width.
