BENNING BENN EV 3-3 Wallbox Tester and Test Adapter with Installation Tester 10239871

The BENNING BENN EV 3-3 is a specialized test adapter that enables comprehensive safety and functional verification of electric vehicle charging stations (wallboxes) in accordance with IEC 61851-1. Unlike generic multimeters or basic test plugs, this adapter simulates vehicle states, cable coding, and fault conditions, allowing electricians and installers to validate the charging station's response with precision. It is designed to work in conjunction with a standard installation tester (such as a multifunction tester or RCD tester) to perform all required measurements, including RCD tripping tests, insulation resistance, and loop impedance, directly at the charging point.

Highlights

• Simulates Control Pilot (CP) states A, B, C, and D to verify charging station communication and power delivery stages.
• Simulates Proximity Pilot (PP) cable coding for 13 A, 20 A, 32 A, and 63 A charging cables, ensuring correct current limit recognition.
• Built-in fault simulation for PE (earth) interruption and CP (control pilot) error, enabling testing of safety shutdown functions.
• LED indication for phase presence (L1, L2, L3) and rotary field direction, providing instant visual confirmation of correct wiring.
• Dedicated PE conductor test button with LED indicator for quick earth continuity check.
• 4 mm safety measurement sockets for L1, L2, L3, N, and PE, allowing direct connection of an installation tester or multimeter.
• Integrated CEE 7/3 (Schuko) socket for connecting an external installation tester to perform RCD tests (Type A, B, B+) and other measurements.
• Separate 4 mm sockets for CP signal measurement, enabling detailed analysis of the pilot signal with an oscilloscope or multimeter.
• Robust design with IP40 ingress protection and operating temperature range from -10 °C to +40 °C, suitable for field use.
• Powered directly from the charging station under test – no internal battery required, ensuring readiness whenever needed.

In daily use

Electricians and EVSE installers will appreciate the BENN EV 3-3's straightforward operation. After connecting the adapter to the charging station's Type 2 plug, the user can sequentially select CP states to verify the station's response: State A (no vehicle), State B (vehicle connected, not ready), State C (vehicle ready, charging), and State D (charging with ventilation). The PP simulation allows checking that the station correctly limits current according to the cable's coding. Fault simulations help confirm that the station disconnects safely when a PE or CP error occurs. The phase indicators and rotary field display immediately reveal wiring errors, while the test sockets and Schuko outlet enable comprehensive testing with a standard installation tester, streamlining the entire commissioning and periodic inspection process.
