FAQ Question?What do the LED indicators on the MT 2-PE/S-24 AC signify?The green LED indicates that the 24V supply voltage is present and correct. The red LED indicates a fault in the protective circuit, signaling that the pluggable module needs to be replaced. Question?Is the protective plug on this MODUTRAB device hot-swappable?Yes, the protective plug can be removed and replaced without interrupting the power to the circuit, thanks to the base element’s design. This allows for quick maintenance without system downtime. Question?What is the function of the ‘FM’ (Floating Contact) terminals on this device?The FM terminals provide a remote signaling contact (a changeover contact). This can be integrated into a monitoring system (like a PLC) to remotely signal the status of the surge protector, such as when the protective element has failed and needs replacement. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
