The CA 742 is a voltage detector for electricians and technicians to carry out the voltage absence test (VAT) in compliance with the EN61423-3 Edition 3 standard: it allows you to intervene on any 600 V CAT installation. IV.
To meet the regulatory provisions of some countries, it is available in two versions: with or without IP2x accessories.
Safety in the event of a power failure via signal LED, which flashes as soon as the voltage is higher than 50 VAC (45-65 Hz) and over 150 VDC.
Complete integrated self-test, for checking electrical circuits, power supply, displays and the good condition of the measurement leads.
The tips and leads are removable.
The self-powered CA 753 measuring accessory (optional) allows quick and complete checking of the 2P+E sockets.
