Switching functions in protection and control circuits contact multiplication.

High speed tripping functions requiring a number of simultaneous switching opertions, interlocks in control and closing circuits.

The relay is intended for use in the applications requiring.

• Increased current carrying or interrupting capability in a contact ( low current contact energizes the coil to close the high current contact)
• Circuit isolation.
• Contact conversion ( for example, from a normally open to normally closed condition), or
• Contact multiplication ( from one contact input to two contact output)
