Splashproof IP44 connectors with nickel plated brass contacts for use in arduous operating environments. Enclosures offer impact resistance from -25 to +55°C and are equipped with glass fibre reinforced nylon contact carriers which have excellent tracking and heat resistance properties. These connectors are ideal for the connection of Star-Delta motors and DOL motors which require auxiliary contacts. They can also be used for electrical interlocking in conjunction with remote control devices, as well as enabling the connection of several lighting fittings on a single phase circuit with a single connector.
