Essential tool for all electricians to check the absence of voltage before any intervention in an electrical installation connected to the network.
The VAT/DDT C.A 771, which complies with the IEC 61243-3 standard, allows intervention in any 1,000 V CAT IV installation. It is rated IP 65 and offers a broad climate class type S, for indoor and outdoor use even in harsh conditions.
To satisfy the regulatory requirements of certain countries, the detector is available in two models, equipped or not with IP 2X test leads. The C.A 771 has a redundant security system in case of power failures; the “ELV LED” flashes as soon as the voltage exceeds 50 VAC/120 VDC.
The control of the differential protection trip (DDR) is protected through the double command system; 2 hands are needed to press the keys simultaneously.CAT IV 1,000 V
The integrated self-test of the C.A 771 allows you to check the electrical circuits, the power supply, the displays and the good condition of the measurement cables.
Practical, simple and fast, the phase rotation is carried out by means of a 2-wire system with a microprocessor.
The acoustic and visual continuity complies with the recommendations of annex B of the standard. Ghost voltage detection, such as unipolar phase identification are also available.
The test lead and cable are removable. The C.A 753 measurement accessory (optional) allows you to quickly and easily control 2P+T, European and Schuko sockets.
