IEC Class I Combined Lightning, Current and Surge Arresters for
230 Volt, 2-Pole TN & TT Systems
Description
The Cooper Bussmann
®
IEC Class I 230 Volt, two-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 rating of 255 volts.

BSPS2255TT(R)
TN System Arresters
The features of these two-pole devices are for use as a modular combined
lightning and current arrester and surge arrester for use in single TN- systems
(“2-0” circuit).
TT System Arrester
Provides a current arresting means for use in single TT- systems
(“1-1” circuit).

Contact Available
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.
