Voltage Testers are IP65 rated.

Press Release Summary:

Voltage Testers are offered in C.A 771 and C.A 773 versions and equipped with IP2X test probes or without. Units come with ELV LED which flashes when the voltage exceeds 50VAC / 120VDC and are EN 61243-3 complaint. Products feature integrated autotest, two-pole phase-sequence testing with 2-wire method and 2-wire microprocessor system. Suitable for detection of live and de-energized AC or DC circuits, testers can detect stray voltages and offer unipolar phase identification.

Original Press Release:

AEMC® Introduces the NEW Voltage Testers Models C.A 771 & C.A 773

An essential tool for electricians to ensure that voltage is not present before working on any electrical equipment or installation connected to the electrical system.

Compliant with IEC 61243-3 Edition 2, the C.A 771 and C.A 773 VAT can be used to work on any 1000V CAT IV installation. They are rated IP65 and offer a Koppen-Geiger type-S extended climatic class for indoor and outdoor use, including weather in extreme conditions.

To meet the requirements of the standards in certain countries, these testers are available in two versions: equipped with IP2X test probes or without. The C.A 771 and C.A 773 have a redundant safety system in the event of power supply faults; the ELV LED flashes when the voltage exceeds 50VAC / 120VDC.

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

The integrated autotest checks the electrical circuits, power supply, displays and the condition of the measurement leads.

Phase rotation measurement is simple and quick with the 2-wire microprocessor system. Audible and visual continuity testing is provided in compliance with Appendix B of the IEC 61243-3 standard. The tester can also detect stray voltages and offers unipolar phase identification.
