Bussmann BSPS4255TNS, BSPS4255TT Data Sheet
1210 BU-SB101431 Page 1 of 2 Data Sheet 1165
Description
The Cooper Bussmann®IEC Class I 230 volt, four-pole, modular combined
lightning, current and 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.
230 Volt models are offered with MCOV ratings of 255 volts.
TNS System Arresters
The features of these four-pole devices are for use in TNS 230/400 volt
systems (“4-0” circuit) against surges.
TT System Arrester
Provides a current arresting means between neutral conductor and protective
conductor in TT 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.
