SPD IEC 1169

Surge Protection Made Simple™ for IEC Applications
IEC Class II Surge Arresters for 230/400 Volt, 4-Pole 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.
BSPM4275TNS(R)
BSPH4275TT(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 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.
