Class I+II+III (T1+T2+T3) Combined Arresters
In the case of single-pole units the individual SPD modules
can optionally be delivered with integrated, non-resetable
thermal sensors (/FM) or (/Pk).
This remote state display for the individual SPD modules
makes a periodical maintenance unneccessary.
This way, with a minimum of additional acquisition costs the
maintenance costs can be reduced considerably.
The sensors are already triggered before a possible damage
of the SPD module, which then has to be replaced for security
reasons.
At an overload of the SPD the sensors open a hermeticallysealed,
potential-free remote contact permanently.
The remote contacts have to be included in the order of the
SPD. Retrofitting is not possible.
The remote signalling contact (FM or Pk) is connected via a
twisted-pair cable to an integrated plug-type terminal block
of the SPD.
The latching hooks per pole on both sides of the SPD allow
for an installation on a 35 mm DIN rail, even under difficult
mounting conditions inside the distributor.
For a supply from below, the labels can be reversed and the
front plate can be turned through 180°. On demand, a second,
self-adhesive front plate can be delivered as a replacement,
free of charge.
