The new CA 742 and CA 762 voltage detectors from Chauvin Arnoux meet the requirements of standard NF C 18-510 as well as those of European standard EN 50110-1, which recommend that installations be de-energized before any intervention.
The NF C 18-510 standard formalizes this securing of the installation by a procedure, the consignment where a check of the real absence of voltage must be carried out by means of a specific device in accordance with standard IEC 61243-3, the voltage detector.
Because it is about safety, the new CA 742 and CA 762 Chauvin Arnoux voltage detectors go even further in the requirements.
- The complete self-test extends from the control of the internal functioning, the batteries, the displays, to the end of the test tips and indicates, if necessary, the nature of the fault.
- The ELV LED, whose intensity increases with voltage from 50 Vac / 120 Vdc, provides redundant and independent safety in the event of power supply faults.
- Voltage detection up to 800 Hz guarantees voltage control on standard 50/60 Hz networks but also on more specific electrical networks encountered for example in maritime or air transport.
- The IP65 degree of protection, much higher than the recommendations, allows indoor and outdoor use on category 4 (CAT IV) installations with mains supply voltages of 600 V with respect to earth.
- The sound and visual continuity test has a specific control and is set to 100 Ω in order to follow the normative recommendations. The C.A 762 also offers an extended continuity test with visual indication for R < 2 kΩ, 60 kΩ et 300 kΩ.
- The digital technology of these devices makes it possible, with the CA 762, to check the order of the phases up to 400 Hz, including behind a generator set, an inverter or an isolation transformer.
- The sound indications exceed 55.5 dB to optimally signal the presence of voltage, phase detection, continuity, etc.
- The cords and the test probes are removable in order to keep the device in perfect condition and at a lower cost.
The CA 742 and CA 762 are offered with 2 equipment levels including an IP2X version which meets the requirements of certain countries including France (NF C 18-510).
