operating principles
■ service connections are the interface between the Utility and the end- user customer.
■ they connect the customer’s electrical installation to the power distribution network.
advantages
■ low-cost product, suitable for conventional service connections.
■ multiple rating device.
■ several levels of earth leakage sensitivity.
■ compiles with the French NFC 61 450 standard.
afety
■ thermal compensation
□ the pôle settings are not affected by the ambient température.
■ residual current device
□ highly reliable, self-powered System
□ immunized against voltage surges of atmospheric origin
□ unintemjpted power supply for greater user convenience.
■ prévention of overvoltage
□ the neutral pôle is designed to close first and open last to maintain a fixed potential.
