Description:
Eaton’s Bussmann™ series three-pole IEC Class II
modular surge arresters for TN-C systems feature
local
easyID™
visual status 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.
MCOV rating are 150V for 120 volt models and
275V or 385V for 230 volt models.

TNC System Arresters
The features of these three-pole devices are for
use in TN-C 120/240 volt or 230/400 volt systems
(“3-0” circuit) against surges.
