CAT IV 1000 V IP65 two-pole Voltage Absence Tester (VAT)

The C.A 773 VAT is an essential tool for electricians to check that no voltage is present before working on any electrical installation connected to the network.

Compliant with IEC 61243-3 Edition 2, it can be used to work on any 1,000 V CAT IV, indoors or outdoors.

To meet the requirements of the standards in certain countries, this tester is available in two versions: equipped with IP2X accessories or without.

The C.A 773 has a backlit digital display in addition to the LEDs for viewing the measurement results.

It is fitted with a redundant safety system in the event of power supply faults; the ELV LED flashes when the voltage exceeds 50 VAC / 120 VDC.

The C.A 773’s comprehensive Autotest checks the electrical circuits, the power supply, the displays and the condition of the measurement leads.

Phase rotation measurement is practical, simple and quick with the 2-wire microprocessor system.

Safety is ensured when testing Residual Current Device (RCD) tripping by means of a double control system; both hands are necessary to press the 2 buttons simultaneously.

Audible and visual continuity testing is provided in compliance with Appendix B of the standard. The tester can also detect stray voltages and offers unipolar phase identification.

The test probe and leads can be removed. The C.A 753 measurement accessory (optional) can be used for quick, easy testing of European and Schuko 2P+E power sockets.
