Bulletin 1492-P Push-in Terminal Blocks

Dramatic Time Savings and Improved Reliability

Features and Benets

• ONE-hand, ONE-second insertion

• No strand breakage or turned
back strands

• Low insertion force

• No retightening

• Easy-to-see terminals from the front

• Universally-located test points for fast
inspection and easy commissioning

• Plastic actuators for shock prevention

• Application-driven designs (power
distribution and sensor/signal blocks)

• No torque values needed to install
or double check

• Quick reference guide for easy
ferrule selection

• Marker areas located on the front and
sides with only four marker card types
needed for the entire product line

This innovative push-in connection technology oers dramatic time
savings by creating wiring eciency. The 1492-P Push-in terminal blocks
provide improved wiring accuracy and reliability insuring a quality
connection that requires no double checking.

When using an automated ferrule machine, installation can be up
to 65 percent faster than screw-type terminal block connections –
a 26 second savings per terminal block. That’s a saving of over seven
hours for every 1,000 terminal blocks connected. Not only is productivity
vastly increased, but the resulting connections eliminate the vibration
failure mode of screw terminals. The push-in connections signicantly
exceed UL pull-out standards.

65% reduction in labor –
saving over seven hours per
1,000 terminal blocks installed

Bulletin 1492-P Push-in terminal blocks oer panel builders, OEMs, and
other high-volume users cost-savings – not only in the form of increased
wiring speed, but also through eliminating connection adjustments and
torque-checking of screws. They are available in a wide range of standard
and application specic oerings, including a unique control power
distribution terminal block.

Ferrule

Ferrules allow a stranded wire to act as a solid wire, so it can
be inserted into the push-in terminal blocks without tools.
Various hand-held or automated crimp tools are available,
depending on the volume of terminations needed.

In addition to the dramatic productivity advantages when
ferrules are used with push-in terminal blocks, they also
provide enhanced connection integrity and safety.

For specic information on which Panduit ferrules to use
with individual Bulletin 1492-P Push-in Terminal Blocks,
consult Appendix sections in Publication 1492-TD017.
