PROJOY PEFS-EL50H-16 firefighter safety switch for 8 strings
The PEFS-EL50H-16 opens the DC circuit of 8 photovoltaic strings whenever the roof has to be made safe: fire, fire brigade intervention, maintenance.
Operation follows the AC mains voltage: while it is there the contacts stay closed; as soon as it goes, the device opens. On top of that there is a thermal release that trips by itself if the internal temperature exceeds 70 °C. The enclosure is self-extinguishing and UV-resistant with an IP66 rating, the internal isolators comply with EN 60947-1 and EN 60947-3 and withstand over 1500 operations under load.
Key strengths
Grid-triggered releaseRemove the AC voltage and the DC array opens by itself.
IP66One of the highest ratings in its class: it stays in the field all year.
Self-extinguishing materialsFlame-retardant, UV-resistant enclosure.
Over 1500 operations under loadInternal isolators sized for a long service life.
Thermal release at 70 °CThe device opens by itself if the temperature rises too far.
Signalling contact24 Vdc output to report the status to the board or the monitoring system.
