CATU MS-920-EX Low Detector

CATU Low Voltage Detector

MS-920-EX

CATU MS-920-EX low voltage detectors are compliant to IEC 61243-3 standards and the European standard EN 50110-1. The MS-920-EX is suitable for indoor/outdoor use and is able to check voltage levels from m 12 to 690V AC, 800V DC.

Safety features include a light indicating the presence of a dangerous voltage (> 50 V), test button to verify correct functionality (threshold of 100 Ω) and a high degree of protection thanks to IP65 and IK06 protection means this voltage detector is suitable for all environments.

The voltage detectors manufactured by CATU Electrical distributed by Thorne & Derrick are designed to carry out electrical safety checks on the absence of voltage during electrical or non-electrical work with the power off and in accordance with the mandatory rules for intervention on work or electrical installation.
