Terminal Blocks : IEC

Disconnect terminal blocks provide a convenient means for isolating and disconnecting control circuits.
The double level terminals facilitate higher termination density without the need to increase the length of the mounting rail. Jumping between terminal blocks can be done at both levels with the circuit bridges. Both levels of the terminal block can also be labeled with terminal block markers.
Certain electrical and control systems require fuse protection – fuse holder terminals offer a convenient solution.
Use of grounding terminals instead of grounding studs and wire lugs to terminate ground wires saves installation and wiring time substantially. Grounding terminals clamp mechanically onto the DIN rail by tightening the center mounting screw, making a reliable electrical connection between the current bar and the DIN rail. The rail serves as a bus bar and automatically distributes ground potential to all other ground terminals on the same rail. Grounding terminals can also be used as end stops, preventing other terminal blocks and components from moving laterally on the DIN rail.
The miniature modular panel mounting screw clamp terminals ensure extremely compact wiring.
c3controls multi-conductor screw clamp terminal blocks offer a reliable solution for multiple wire connections. The terminal eliminates conventional cross connections, looping wires and reliability problems encountered when connecting two wires in one clamp. The terminals provide multiple connection points in the terminal itself, and the possibility of further multiplication of connections with circuit bridges. The multi-conductor terminal blocks can even be bridged to standard feed-through screw clamp terminal blocks of the same conductor size.
The triple level terminals are ideal for control systems with three wire DC sensors and actuators. The simplified three level connections facilitate higher wire termination density.
c3controls WTB2 Series of feed through spring clamp terminal blocks have been designed to meet the strict specifications and standards of UL, CSA, and IEC. Manufactured with a direct mounting foot for 35mm standard DIN rails. Wiring to the terminal blocks is made easy by the IP20 funnel entry design of the housing.
Spring clamp ground terminal blocks are offered for quick connections and are ideal for use with other spring clamp terminal blocks. The spring clamp is operated by using a screwdriver to provide access for wiring through the opening in the spring clamp. The wire is held against current bar directly by a pre-stressed clamp ring. Specially designed alloy feet help to achieve very low contact resistance and vibration proof grounding. Spring clamp ground terminals can be mounted on 35mm DIN rails along with other terminals, and eliminates the need for a separate grounding bus bar. The ground terminal block profile is the same as the feed through terminal blocks of same wire size.
