The tester uses capacitive coupling to sense electric fields around live cables, terminals and switch gear, providing both visual LED indication and an audible beep when voltage is present.\u003c\/p\u003e\n\u003cp\u003eDesigned for electricians, facilities maintenance and DIY users checking for live circuits before working on installations, the TE4B fits in a tool belt or pocket at 159mm long and 27.5mm thick. The tester operates on two AAA batteries (sold separately) and features an on\/off control switch to prevent accidental activation during storage or transport. The CAT III overvoltage category rating means it's suitable for use on fixed installations up to 1000V including distribution boards, sub-mains and final circuits.\u003c\/p\u003e\n\u003cp\u003eThe blue polycarbonate body provides impact resistance and electrical insulation, while the tapered white tip allows the sensor to be placed into tight spaces around terminals and cable entries. The IP20 rating makes this suitable for indoor dry electrical environments but not outdoor or damp locations. The on\/off switch extends battery life between uses and prevents false alerts from ambient electromagnetic fields when the tester is off.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e159 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e21 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e27.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePolycarbonate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eBlue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_4275849_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does CAT III mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCAT III is an overvoltage category rating indicating the tester is designed for use on fixed installations including distribution boards, sub-mains and final circuits up to 1000V.
