INFORMATION
CAT. NO. 3861-ETH
Surge
Protective
Devices (SPD)
for Ethernet
Data Networks
APPLICATION
The Cat. No. 3861-ETH is designed to
UL 497B Listed
provide transient voltage surge suppresfor Data Communication
Circuits
sion for products operating on Ethernet
data networks. The 3861-ETH comes with
both RJ-45 input and output connectors.
This unit provides low clamping voltages
and the ability to withstand high transient current surges that may be encountered on
Ethernet PLC ports operating in harsh electromagnetic environments or in geographic
areas where a high probability exists of encountering the damaging effects of lightning
induced transients.
FEATURES AND BENEFITS
■ The 3863-ETH is supplied with a non-conductive DIN rail-mounting mechanism
designed for 35mm Standard and 32mm “G” type rails
■ SPD units are designed to provide transient voltage protection using connections
compatible with readily available off-the-shelf RJ45 jacks
■ SPD’s offer two ground-connection options: a ground plate for direct connection to
ground-stud terminals and a pig-tail lead for direct connection to any ground bus
■ SPD’s offer dual-redundant protection paths for transients entering into or out of the
units with automatic reset-PTC fusing
■ SPD’s are backed by Leviton’s 5-year limited warranty
STANDARDS AND SPECIFICATIONS
The Cat. No. 3861-ETH is designed to provide transient voltage surge protection for
Ethernet data networks. The device is equipped with two options for a ground connection:
1. A ground tab to facilitate direct connection to equipment ground frame systems;
2. A low inductance ground braid strap, for use when mechanical mounting constraints
preclude the use of the metal ground tab. The 3861-ETH is also supplied with a nonconductive DIN rail-mounting mechanism designed for 35mm Standard and 32 mm “G”
type rails.
