The matt:e SP-EVCP-T(W) is a single-phase EV charger connection centre providing built-in PEN fault protection for residential electric vehicle charge point installations. It allows an EV charger to be safely connected to a PME (Protective Multiple Earthing) supply without the need for earth electrodes, removing the disruptive groundworks and risk of striking buried services that earth rod installation typically involves.
Fitted with three incoming terminals (the 'T' variant), this unit continuously monitors the incoming supply voltage and automatically disconnects the EV charger, including the CPC, if a PEN fault or other supply anomaly is detected, protecting both the vehicle and the property's electrical installation.

Installer requirement: This product must be installed by a competent person in accordance with the IET Wiring Regulations, BS 7671 (18th Edition or later), and any relevant Building Regulations. All relevant supplies must be fully isolated or disconnected before commencing installation or removing the enclosure cover, as the unit carries a live mains supply (230V or higher) once installed.
Single-phase PME only: The SP-EVCP-T(W) is designed exclusively for domestic dwellings with a single-phase PME power supply and is not suitable for three-phase supplies. It must be connected via the Consumer Distribution Board or 'Garage Board' with a suitable protective device (the 'R' variant, sold separately, is the only version rated for direct connection to meter tails).
Built-In matt:e PEN Fault Technology
An electronic detection circuit continuously monitors the incoming supply. On detecting a fault condition sustained for 4 seconds, the circuit de-energises the contactor, disconnecting Line, Neutral, and CPC from the load, isolating the EV charger from a compromised PME supply.
No Earth Electrode Required
By eliminating the need for a dedicated earth rod, the SP-EVCP-T(W) avoids costly groundworks and removes the risk of striking buried services during installation, a common practical barrier to PME-based EV charger installations.
Three-Pole Certified Contactor
The internal isolation contactor is certified to BS EN 60947-4-1 and complies with the requirements of BS 7671 18th Edition, providing a robust switching mechanism for repeated fault-driven disconnection cycles over the unit's service life.
Wire-In, Wire-Out Simplicity
The 'T' variant provides three incoming terminals ahead of the contactor, allowing a straightforward connection from the distribution board and out to the charger's L, E, and N terminals, without additional protective devices built into this specific unit.
Automatic Recovery Logic
Once a fault is cleared, the unit does not reconnect immediately. The monitored supply must remain stable and within correct limits for a period of 3 minutes before the contactor re-energises, preventing nuisance cycling on a marginal or intermittent fault.
Dual-Colour Status Indication
A red/green LED gives a real-time visual status of the unit, distinguishing normal operation from over-current, under-voltage, over-voltage, DC detection, and internal error states, supporting faster fault diagnosis on site.

What does the SP-EVCP-T(W) protect against?
It continuously monitors the incoming single-phase supply voltage and automatically disconnects Line, Neutral, and CPC from the EV charger if a PEN fault or other out-of-range voltage condition is detected for 4 seconds, protecting the vehicle and installation from an unsafe PME supply.
Does this unit require an earth electrode to be installed?
No. The built-in matt:e PEN fault protection technology allows the unit to connect an EV charge point to the existing PME earthing facility without earth rods, avoiding additional groundworks.
Can the SP-EVCP-T(W) be used on a three-phase supply?
No. This unit is designed exclusively for single-phase PME supplies in residential settings and must not be used on premises with a three-phase electricity supply.
How is the SP-EVCP-T(W) different from the R, M, and B variants?
The 'T' version has three incoming terminals with no additional built-in protective device. The 'M' version adds a 2-pole MCB, the 'R' version adds a 2-pole Type A RCBO (and is the only variant rated for direct meter tail connection), and the 'B' version adds a 2-pole Type B RCCB plus a single-pole MCB. All other variants must be connected via the Consumer Distribution Board or Garage Board.
How long after a fault is cleared before the charger reconnects?
The contactor remains de-energised until the monitored supply returns to the correct level and remains stable for a continuous period of 3 minutes, after which the EV charger is automatically reconnected.
