■ Extra protection with regard to indirect contact

ELCB relays, multiple protective earthing or earthing

can be used as extra protection, provided that

local safety regulations are complied with. In

the case of an earth fault, a DC content may

develop in the faulty current.

Never use ELCB relays, type A, since such relays

are not suitable for DC fault currents.

If ELCB relays are used, this must be:

• Suitable for protecting equipment with a direct

current content (DC) in the faulty current

(3-phase bridge rectifier)

• Suitable for power-up with short charging

current to earth

• Suitable for a high leakage current
