451 Series Terminal Blocks
Type WN screw clamp series
Rising cage clamp technology ensures low contact resistance due
to large surface area, while providing a vibration proof contact
One-piece threaded collar guarantees functionality, even after
repeated tightening and loosening of screws
Clamping screws are securely held within the insulated housing
to help ensure a secure connection
Metal parts provide low contact resist-
ance and high corrosion resistance
Polyamide insulating material is
rated UL 94V-0 and has excellent
chemical and mechanical properties
A variety of block styles are available,
including feed through, ground,
branch and multitier versions
Type WF spring clamp series
Screwless spring clamp technology ensures tight, robust
connections that are protected against movement
Wire entry and screwdriver access are on the same plane,
allowing for neat, easy wiring in tight spaces
Test points are built in for all clamping points, so removal of
wire is not required to test connection
Metal parts provide low contact
resistance and high corrosion
resistance
Polyamide insulating material has
excellent electrical, chemical and
mechanical characteristics and is
rated to UL 94V-0
A variety of block styles are available,
including feed through, ground,
branch and multitier versions
Type WC insulation displacement
contact series
The industry’s narrowest blocks provide wide-ranging
flexibility in configuration and applications
Secure, gas-tight and vibration-resistant connections are ensured
as the contact design moves the clamp to engage the wire
Special alloys and surface treatments make this block ideally
suited for use under extreme conditions
Polyamide insulating material is rated UL 94V-0 and has excellent
chemical and mechanical properties
A variety of block styles are available, including feed through,
ground, branch and multitier versions
