for electrical installationsremote signalingDC power

Short description
Modular surge arrester for d.c. applications with floating remote signalling contact.

Key features

• Universal combined arrester/ surge arrester consisting of a base part and a plug-in protection module
• Device concept specifically developed for use in d.c. circuits
• Powerful d.c. switching device (DCD) prevents fire damage caused by d.c. switching arcs
• Use without additional backup fuse in defined applications
• Operating state / fault indication by green / red indicator flag in the inspection window
• Easy replacement of protection modules without tools due to module locking system with module release button
• Floating remote signalling contact (changeover contact)
• Modular, pluggable design; width of 6 DIN modules
