2491B Cable Description
2491B / 6701B is designed for applications such as switch controls, relays, and instrument panels for power switchgear, as well as internal connectors in rectifier equipment, motor starters, and controllers. Its flexibility makes it easier to install in tight spaces such as control cabinets and conduits.
2491B / 6701B uses EI5 type thermosetting LSZH insulation material. These cables do not produce corrosive gases when burned, which is particularly important for installing electronic equipment.
