Description
The Cooper Bussmann®IEC Class II 120/240 volt and 230/400 volt, threepole, 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.
120 Volt models are offered with a MCOV rating of 150 volts.
230 Volt models are offered with a MCOV rating of 275 or 385 volts.
TNC System Arresters
The features of these three-pole devices are for use in TN-C 120/240 volt or
230/400 volt systems (“3-0” 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.
