Bussmann BSPS3255TNC Data Sheet

1210 BU-SB101430 Page 1 of 2 Data Sheet 1164

Description

The Cooper Bussmann®IEC Class I 230 Volt, three-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 a MCOV rating of 255 volts.

TNC System Arrester

The features of these three-pole devices are for use in TN-C 230/400 Volt
systems (“3-0” 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.
