Terminal Blocks

our complete
line of terminal
blocks
Stainless steel screws
and serrated current
bars provide a strong,
corrosion-resistant grip.
OMEGA’s OMTBV7-W terminals
are designed to meet the three
most important criteria when
selecting a terminal block line –
ease of wiring, secure connections
and durability. The line is also
comprehensive, offering a wide
array of terminal types for most
circuits and functions, from control
to low level power.
The Size You Need
OMTBV7-W feed-through terminals
come in ten sizes and are rated
to 600 Vac (800V-IEC). They
accommodate a full range of wire
sizes from 30 AWG to 3/0 AWG
(0.5 mm
section). Many "specialty" feedthrough terminals are also available
that provide multiple terminations or
increase the density of connections.
This reduces panel space and
saves money.

Comprehensive Selection of
Special Terminals
Aside from the broad selection of
standard feed-through terminals,
many special terminals are also
part of the OMTBV7-W line,
including:
U Two level terminals
U High Current terminals
U Ground terminals
U Dual connection terminals
U Diode and resistor terminals
U Plug-in style terminals
U Various isolating terminals
U Fuse terminals
U Sensor terminals
U Thermocouple terminals
U Proximity switch terminals
Even the most varied circuit
requirements can be supported
by the broad selection offered with
this line.
Super Reliable Connections
The most important aspect of
a terminal block is to join wires
in a reliable connection. With
OMTBV7-W terminals, a cone
shaped guide allows easy insertion
of the wire into a nickel plated
barrel. As tightening torque is
applied to strong stainless steel
screws, the wire is secured
between a recessed contact

pad and serrated current bar.
This corrosion-resistant clamping
mechanism provides excellent
performance in the most demanding
industrial conditions.
Superior Insulation and
Protection Features
All metal parts are recessed,
providing a touch-safe, dead
front design for optimum safety.
Terminal bodies are manufactured
from Polyamide 6.6, known for its
excellent thermal stability, impact
resistance and resistance to
electrical creepage. The insulating
cases are rated up to 90°C (195°F)
for continuous operation. They also
stay elastic down to -40°C (-40°F)
without fracturing.
International Approvals
OMEGA’s OMTBV7-W terminal
block line is UL recognized and
CSA Certified. Many terminals
have also been certified for use in
hazardous locations. The line also
carries the CE Mark for use in most
international markets.
