3-wire sensor installation and our fuse holder terminal blocks accept IEC and North American
control circuit fuses (5 x 20mm or 5 x 25mm and 1/4” x 1-1/4” fuses). In applications where

Our IEC terminal blocks accept wires as small as 0.5mm2 (24
AWG) and as large as 120mm2 (4/0 AWG), and up to 232 amps.
SPECIAL FEATURES
Wide Range of
Operation
A wide range of terminal blocks available from 5mm – 25mm
in screw clamp, power distribution, and spring clamp, with
ratings from 20A to 232A that meet UL and IEC standards.
Screw Clamp
Wiring Made Easy
Wiring to the terminal blocks is made easy by the funnel
entry design of the housing and our spring clamp features
convenient top wiring.
Vibration
Resistant
The pre-loaded 302 stainless steel spring clamps hold the wire
securely against the current bar and won’t loosen, even in high
vibration applications.
Heavy-Duty
Construction
Our terminal block housing is molded out of an unbreakable
thermoplastic and we use quality zinc plated brass and
electrolytic copper for our metal parts for excellent
conductivity and to minimize corrosion.
Visible
Certifications
Our product certifications and electrical ratings are clearly
marked on the outside of the terminal blocks for easy
reference during installation.
