Eaton 144122 SOL30-SAFETY/2MC4-U (230V50HZ) 30A MC4 fireman switch

DC load break switch (32 A) with undervoltage release 230 V, 50HZ in IP65 housing, this is mounted in the immediate vicinity of the PV modules and inserted into the direct current line to the inverter, the ""PV fire brigade switch"" offers two switch positions, in the POWER switch position the current is passed from the PV modules to the inverter, in the SAFETY switch position both direct current lines are interrupted - the switch can also be locked, for example for maintenance work in larger solar systems, but the integrated undervoltage release means that the switch can also be operated from a remote location using a PV off button, if the fire brigade disconnects the entire house from the power grid in the event of a fire, this automatically triggers the PV fire brigade switch and thus disconnects the PV lines from the voltage, a danger to the emergency services in the event of a fire - due to live DC lines - is therefore completely excluded, feedback of the switching state by means of auxiliary switch 1 NO and 1 NC, the switch is tested according to IEC/EN 60947-3 and can be used for ambient temperatures up to 60° C, the maximum operating voltage Ue is 1000 V DC, the maximum operating current Ie is 32A. Input: 2 x MC4 / Output: 1 x MC4 plug connection.
