Description

The Cooper Bussmann IEC Class II 275, 320, 385, 440 and 600 volt, one­pole, 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.

Class II single-pole surge arrester models are offered with MCOV ratings of
255, 275, 320, 385, 440 and 600 volts.

TN System Arresters

The features of these single-pole devices are for use as a single device or in
combination with other devices.

TT System Arrester

Provides a current arresting means between neutral conductor and protective
conductor in TT systems, this device helps ensure fulfilling the requirements
for protection of personnel and equipment in “3+1” and “1+1” circuits.

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.
