Description
The Cooper Bussmann®IEC Class II 230/400 volt, four-pole, modular surge
arresters feature local,
easy
ID™ visual indication and optional remote contact
signaling. The unique module locking system fixes the protection module to
the base part. Modules can be easily replaced without tools by simply
depressing the release buttons. Integrated mechanical coding between the
base and protection module ensures against installing an incorrect
replacement module.
These 230 Volt models are offered with MCOV ratings of 275, 320 or 385
volts.
TNS System Arrester
The features of these four-pole devices are for use in TNS 230/400 volt
systems (“4-0” circuit) against surges.
TT System Arrester
The features of these four-pole devices are for use in TT and TN-S 230/400
volt systems (“3+1” circuit) against surges.
Remote Signaling Contact
The three-pole terminal remote signaling contact versions have a floating
changeover contact for use as a break or make contact, according to circuit
concept.
