Greenlee TR-12A Non-Contact Voltage Detector, Self-Testing

Greenlee TR-12A Non-Contact Voltage Detector, Self-Testing

The Greenlee TR-12A Non-Contact Voltage Detector is a self-testing safety tool designed to identify the presence of AC voltage without direct contact with a live conductor. Rated for 50 - 1000 VAC at a frequency range of 50 - 500 Hz, this Universal detector is engineered to detect voltage in tamper-resistant and conventional 15A and 20A, 120V outlets, lighting fixtures, circuit breakers, wires, and cables, or to locate a break in a wire. It carries a Measurement Category of CAT IV, 1000V and is C/US ETL Listed and CE Compliant, making it suitable for demanding electrical troubleshooting tasks performed by professional electricians and maintenance technicians.

Key Features

• Voltage Rating: Detects AC voltage from 50 - 1000 VAC across a frequency range of 50 - 500 Hz for broad application coverage.
• Non-Contact Detection: Safe, self-testing, non-contact design lets users check for live voltage in outlets, lighting fixtures, circuit breakers, wires, and cables, or locate a break in a wire, without touching energized conductors.
• Automatic Self-Test: Patented automatic self-test verifies the integrity of the unit each time it is used, giving technicians confidence that the tool is functioning properly before every test.
• Outlet Compatibility: Detects voltage in tamper-resistant and conventional 15A and 20A, 120V outlets for use across a wide range of residential and commercial receptacles.
• Alert System: Bright LEDs flash and an audible alarm sounds when voltage is present, with a silent-mode feature available for use in quiet settings.
• Battery-Powered Operation: Runs on (2) 1.5V AAA batteries, included with purchase, and automatically turns off after five minutes of non-use to conserve battery life. A low battery indicator alerts users when replacement is needed.
• Measurement Category: Rated CAT IV, 1000V for use in demanding electrical environments requiring a higher category of overvoltage protection.
• Domestic Build: Designed and assembled in USA and backed by a Lifetime Warranty.
