Marathon/Kulka 600 GP series terminal blocks are designed for reliable electrical connections in industrial environments. Constructed with a phenolic base and plated brass terminals, these blocks provide durability and efficient current transfer. They support a wire range of #14 - #22 AWG with a 15 Amp capacity. The open-back design allows for voltage rating adjustments with an insulator strip (see page 112). Hardware options are available to suit diverse mounting and connection needs. Refer to the datasheet for detailed dimensions and accessory options.
