Surge Protection Made Simple™ for Wind Power Applications IEC Class II Surge Arresters for 230/400 Volt, TNS & TT Systems 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. BSPM4230WE(R) BSPH4230WE(R) These 230 Volt models are offered with MCOV ratings of 275 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 Signal Visual Status Indication Remote Signaling Contact 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.
