Bussmann BSPH2275TT, BSPM2275TN Data Sheet
1210 BU-SB101433 Page 1 of 2 Data Sheet 1167
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.
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
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.
