Two-pole IEC Class II surge arresters for TN and TT systems
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).
Optional remote contact signaling
The three-pole terminal remote contact signaling
option has a floating changeover contact for use
as a break or make contact, according to circuit
Remote contact

Description:
Eaton’s Bussmann™ series two-pole IEC Class II
modular surge arresters for TN and TT systems
feature local
easyID™
visual satus indication and
optional remote contact signaling. The unique
module locking system fixes the protection
module to the base. 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.
