General Information:
Marathon DIN Rail Terminal Blocks are ideal for various applications such as machine tool controls, distribution and instrumentation
installations, switchgear, elevator and panelboard construction.
Insulating Materials:
The moldings are made of Nylon 6/6, Gray. This material has high creepage resistance and high impact strength. It also has a UL
94V-2 flammability rating and is resistant to gasoline, oil, alcohol and many other chemicals.

Connector System:
The connectors are made of copper alloy and are nickel-plated for corrosion resistance. The screws are rolled steel, zinc plated.
The total connector system provides the following benefits:
1. The system ensures that no matter how small the cross section of the wire it can only be inserted into the connection hole.
2. A serrated pressure plate eliminates any wire damage from the torquing of the screw.
3. The upward pressure on the screw from the pressure plate reduces the risk of a screw loosening due to vibration.
4. The pressure plate also compensates for some reduction in contact pressure caused by cold flow in the wire.
5. The design of the pressure plate and its heavy construction eliminates tilting, even with solid wires.
6. The use of rolled rather than turned screw threads provide for the application of higher torque without thread damage.
