ABB 1STQ007121B0000 System pro E power horizontal installation kit for two compatible Tmax XT5 3-pole or 4-pole moulded case circuit breakers, designated for 400 A applications in 600 mm wide low-voltage switchboard structures.
£556.30
The ABB 1STQ007121B0000 is a dedicated XT5 circuit breaker installation kit designed for integration into ABB System pro E power low-voltage electrical distribution switchboards. Identified by the manufacturer designation 2 XT5 KIT 3-4P WITH.I 400A HORIZ. W=600, this accessory is intended for the horizontal installation of two compatible ABB Tmax XT5 moulded case circuit breakers within a 600 mm wide switchboard configuration.
As part of the ABB System pro E power range, the kit supports the modular assembly of professional electrical distribution panels. Its configuration is specifically associated with two XT5 circuit breakers, accommodating compatible 3-pole or 4-pole arrangements and a 400 A current rating as specified in the manufacturer's product designation.
The ABB 1STQ007121B0000 provides a practical solution for electrical panel builders and switchboard manufacturers requiring an application-specific mounting arrangement. Its horizontal configuration and compatibility with 600 mm wide System pro E power structures help simplify switchboard planning and support the organised installation of protective switching equipment in industrial and commercial power distribution systems.
The ABB 1STQ007121B0000 XT5 installation kit is designed to support the integration of moulded case circuit breakers into compatible ABB System pro E power electrical distribution switchboards. Its dedicated configuration allows two compatible XT5 devices to be arranged horizontally within a 600 mm wide switchboard structure.
The ABB Tmax XT5 circuit breaker series is used in low-voltage electrical distribution systems to provide switching and circuit protection functions when equipped and configured appropriately. The 1STQ007121B0000 is an installation accessory for these devices rather than a circuit breaker itself. The protection functions, breaking capacity and trip characteristics of the completed installation depend on the separately selected XT5 circuit breakers and their associated trip units.
The ABB System pro E power range provides a modular platform for constructing low-voltage distribution switchboards. Its configurable enclosure structures and dedicated equipment installation accessories support flexible arrangements of protective devices, power distribution components and associated electrical equipment.
For correct installation, the 1STQ007121B0000 should be used with compatible XT5 circuit breakers and the appropriate System pro E power structure. Electrical panel builders should follow ABB assembly instructions and verify the complete installation against the applicable electrical design, connection requirements and switchboard assembly standards, including IEC 61439 where relevant.
The ABB 1STQ007121B0000 is an installation kit designed for mounting two compatible ABB Tmax XT5 moulded case circuit breakers horizontally within a 600 mm wide ABB System pro E power switchboard configuration.
The kit is designated for the installation of two compatible ABB Tmax XT5 circuit breakers in a horizontal arrangement.
The ABB 1STQ007121B0000 is designated for compatible 3-pole and 4-pole ABB Tmax XT5 circuit breakers. The selected devices must match the installation requirements of the kit.
The manufacturer designation specifies a 400 A current rating and a 600 mm nominal switchboard width. The installation arrangement is horizontal.
The ABB 1STQ007121B0000 is identified as a circuit breaker installation kit, not as a complete circuit breaker assembly. The required XT5 circuit breakers, their trip units and any additional installation components should be selected and confirmed separately according to the switchboard design and supplied kit contents.
ABB System pro E power installation accessories support the professional assembly of modular low-voltage electrical distribution switchboards. The ABB 1STQ007121B0000 provides a dedicated horizontal installation arrangement for two compatible Tmax XT5 circuit breakers, helping electrical engineers and panel builders create organised and application-specific switchboard configurations.
