Intended use

Unit manufactured in accordance with Directive 2014/34/EU

The MVS 6 PTC thermistor triggering system is a safety, monitoring and control device according to Art. 1 (2) of Directive 2014/34/EU for equipment and protective systems in potentially explosive atmospheres. The triggering system must be fitted outside the potentially explosive atmosphere. Our EU declaration of conformity is enclosed with these instructions.

Application areas

The triggering system is used for temperature monitoring of three-phase AC motors, intended for use in potentially explosive atmospheres and classified in group II, categories 2 G or 2 D. The system is also suitable for protecting other three-phase devices from excessive temperatures, provided these devices are equipped with PTC thermistors and have similar switching behaviour to three-phase AC motors. The correct selection of the protective system for the intended use is the responsibility of the operating company.

The MVS 6 system is also used to switch the connected motor on and off during operation. The switch on the front of the housing can be locked in the “off” position using a padlock.
