Review
What this product is
Written after the analysis, from the same sources the score is built on: the manufacturer's documentation, available studies and verified owner feedback.
The KeContact P40 suits owners who want a well-documented, well-tested wallbox and are happy to pay for it. KEBA states that the P40 integrates an RCCB Type A together with an RDC-DD, i.e. 6 mA DC fault-current detection, so the residual-current protection is built in rather than left to the installer's parts list. Phase switching between one and three phases is integrated for PV-surplus charging, and the unit speaks OCPP 1.6, Modbus, a REST API, LAN, WLAN, Bluetooth and RS485.
The evidence is the strongest in this ranking. In ADAC's company-car wallbox test of 11 December 2025 the KEBA KeContact P40 scored 1.6 and won; note that ADAC tested a company-car configuration, while the 131.736 listed here is the version with an uncalibrated meter. ISO 15118 is only an option on the standard P40, and the MID meter is too: The Mobility House lists MID variants of the P40 at €1,010–1,059 instead of €959.
What is missing: KEBA's overview page gives no standby figure, no IK rating and no temperature range in numbers, and at 476 mm tall and about 6.2 kg it is the largest box here. If you need to bill home charging to an employer, budget for the MID variant from the start.

FAQ
Frequently asked questions
Does the KEBA P40 need a Type B RCD in front of it?
KEBA states that an RCCB Type A and 6 mA DC detection (RDC-DD) are integrated. The final protection concept is set by your electrician under local wiring rules.
Can I bill my employer for home charging with the 131.736?
Not reliably: its meter is listed as uncalibrated. The Mobility House sells MID-metered P40 variants at €1,010–1,059.
