110V DC Relay

[Ian Frame]

I am looking for a 110V DC operated relay with two normally closed
contacts which are capable of interrupting 110V DC load at 10 Amps
(resistive). I have looked high and low with no success,can anyone help.

Makes mercury displacement relays and their high voltage line includes
125vdc coils and an option for NC contacts.

For a normal relay you need a magnetic blow out option, these used to
be available from Potter & Brumfield, now part of Tyco Electronics:

An Australian company
has what you want the 10 amps is achieve with magnetic blow-out relays.

Last time I looked for something like that I noticed Weidmuller had a DC
relay in that current rating. When I ordered it though it was not in stock
with a long delivery.

You might consider using an old trick which was used by manufacturers to
give AC relays/contactors a DC rating. They wired a number of contacts
(with the needed AC amp rating) in series to improve the ability to
interrupt the DC current. 2 - 3 contacts are usually needed for each circuit
depending on the inductance of the circuit.

A coil with that voltage should be a bit easier to get.
