LC Series In-Line Surge Protective Device and Noise Filter
The LC Series SPD offers high-quality surge protection and noise filtration for any microprocessor-based product,
computer, analyzer, PLC, motion control system, original equipment manufacturer (OEM), or any sensitive single phase
load. The LC can be connected to the incoming power source (20 A or less) to isolate the control cabinet from the
outside environment. This product is ideal for panel builders as well as manufacturers and integrators of instrumentation
cabinets for industrial, commercial, or residential applications. The LC uses a series/hybrid suppression circuit that
delivers 40,000 peak amps of surge protection with true sine wave tracking protection up to -75 dB of noise filtration.

Secondary Surge Arresters
The Secondary Surge Arrester (SDSA) series products are designed primarily to protect against external surges at service entrance panels. They
are designed and tested to be used on the line side or the load side of the main service disconnect switch. These devices may also be used for
surge protection of irrigation pumps, oil pumps and motors operating below 600V.
Hard-Wired Secondary Surge Arresters
SDSA1175
The SDSA1175 Secondary Surge Arrester is designed and listed for indoor or outdoor installation and surge protection
of single-phase three-wire 120/240 Vac 60 Hz electrical services and major appliances. Two SDSA1175 Secondary
Surge Arresters can be installed to provide protection on 208Y/120 Vac three-phase four-wire services.
The SDSA3650 Secondary Surge Arrester is designed and listed for indoor or outdoor installation and surge protection
of three-phase grounded electrical services up to 600 Vac. and is used extensively in service entrance panels to provide
an efficient and economical means of surge protection.
