The Mempower XP Trunking System is available in ratings from 500A to 6300A.

Mempower XP trunking utilises aluminium-extruded housing bringing significant weight saving advantages whilst ensuring that strength and rigidity is enhanced.

These user-friendly features combine to maximise performance standards and greatly reduce installation times.

Major innovations have been incorporated into the 500A-2500A Mempower XP system: the velocity joint, velocity angle and radial velocity angle provide inherent flexibility.

The velocity joint, eliminates the need for additional joint plates between the ends of conductors and simplifies alignment of successive lengths. The velocity angle dispenses with the need for a separate 90° angle joint and the radial velocity angle can be specified where an edge angle is required between 0° and 90°.

The major innovation of the XP range up to 2500A is the velocity joint, which is integral to the main body of the trunking dispensing with the need for a separate joint pack.

Contact faces of the velocity joint are formed by the conductors which are flared at each end. These slide over one another when offered together to form the completed joint.

The joint is held central by an insulated single bolt. So that at the correct torque the force generated compresses the joint faces. This design prevents the common problem of joint plates deflecting under the bolt force.

Operating efficiency is enhanced by removing the requirement for additional joint plates to bridge the gap between the ends of conductors. Removal of joint plates from the trunking design reduces the number of resistive connections in every joint by 50%.

Trunking can be supplied with up to 5 tapping outlets on each side of a standard 3m length. However, individual requirements can be catered for.

The following configurations are offered as standard:

• Single Phase & Neutral
• Three Phase
• Three Phase & 100% Earth Bar
• Three Phase & Neutral
• Three Phase & Neutral + 100% Earth Bar
• Three Phase & 200% Neutral
• Three Phase & 200% Neutral + 100% Earth Bar

Mempower XP trunking has been designed to make the earth bar a true clean earth on request to complement these configurations.

Mempower XP Tap-off units are designed to provide its customers with the maximum choice of circuit protection devices combined with minimised fitting and removal time. Together with the XP trunking 'tapping outlet design' the tap-off units ensure ease of fitting or removal. Mechanical and electrical interlocks provide maximum safety, combined with 'earth make first / break last' feature.

IP ratings are in line with the XP trunking choices from IP4X - IP54.

Inclusive circuit protection devices range from:

• Fusible: 10 - 800A
• Current limiting MCCBs: 16 - 1600A

Special enclosures for non-standard applications can be provided.

NOTE: Above 800A, tap-offs are fixed.
