Furse transient overvoltage protectors are
maintenance free and have long lifetimes -
essential criteria for trackside equipment
Accepted for use on Network Rail infrastructure. NRS PADS
references: ESP SSI/M - 086/047066; ESP SSI/B - 086/047067;
ESP SSI/120AC - 086/047058 and ESP SSI/140AC - 086/047059
(Network Rail Approval PA05/00471)
Very low let-through voltage (enhanced protection to BS EN 62305)
between all sets of conductors - Full Mode protection (ESP SSI/120AC
and ESP SSI/140AC) and all signal lines (ESP SSI/M)
ESP SSI/B (or ESP SSI/B/G) modified base can be permanently wired into
the system
ESP SSI/M plug-in protection module can be replaced without
interfering with the operation of the system
ESP SSI/B (or ESP SSI/B/G) incorporates a 100 Ω terminating resistance
that can be connected if required
ESP SSI/B (or ESP SSI/B/G) can be flat mounted, or a built-in DIN rail
foot allows simple clip-on mounting to top-hat (ESP SSI/B) or G DIN rails
(ESP SSI/B/G)
ESP SSI/120AC and ESP SSI/140AC are a compact size for easy installation
in trackside cabinets and control rooms
ESP SSI/120AC and ESP SSI/140AC have three way visual indication of
protector status and advanced pre-failure warning
Features and benefits
To prevent transient overvoltage damage to Solid State Interlocking (SSI)
systems, protectors should be fitted in trackside cabinets and equipment
rooms, on both the data link and the mains power lines.
For single phase mains power supplies of 90-150 Volts, use the
ESP SSI/120AC (formerly ESP 120X)
For single phase mains power supplies of 90-165 Volts, use the
ESP SSI/140AC (formerly S065)
For SSI data links, use the ESP SSI/B (or ESP SSI/B/G) base unit with the
ESP SSI/M protection module
Use ESP PTE002 SSI tester for line-side testing of SSI/M modules.
Application
Network certification
Combined Category C, B tested data link protector and Combined
Type 2 and Type 3 tested mains protector (to BS EN 61643) suitable for
Solid State Interlocking (SSI) mains power and data links. Protectors
are Network Rail approved. For use on lines running within buildings
at boundaries up to LPZ 1 through to LPZ 3 to protect sensitive
electronic equipment.
ESP SSI/B: Connect in series with
the data link either near where it
enters the trackside location
cabinet or the equipment room.
ESP SSI/120AC and ESP SSI/140AC:
Install in parallel, within the
trackside cabinet or equipment
room. The protector should be
installed on the load side of the
fuses, at the secondary side of the
step-down transformer. Connect,
with very short leads, to phase (BX),
neutral (NX or CNX) and earth.
