DG M TT 385 (952 311)
Modular surge protector for TT and TN-S systems (3+1 circuit)
Complete pre-wired unit, consisting of a base and removable protective modules
Energy coordination with Red/Line series products
Zinc Oxide Varistor with high discharge capacity for high current capacity / Spark Gap
The SPD is equipped with an integrated "dynamic thermal disconnection" device, offering high reliability.
The release button of the modular locking system makes it easier to replace protective modules without tools.
Conducted impact and vibration tests according to EN 60068-2 standards via SPD
