Surge Protection Made Simple™ for IEC Applications IEC Class II Surge Arresters for 230 Volt, 2-Pole TN & TT Systems Description The Cooper Bussmann® IEC Class II 230 volt, two-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. BSPM2275TN(R) BSPH2275TT(R) 230 Volt models are offered with MCOV ratings of 255 and 275 volts. TN System Arresters The features of these single-pole devices are for use in single-phase 230 volt TN systems (“2-0” circuit). TT System Arrester The features of these single-pole devices are for use in single-phase 230 volt TT and TNS systems (“1-1” circuit). Remote Signaling Contact Visual Status Indication Remote Signal Contact Available 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.
