Does Eaton have a replacement for an obsolete TI-2 Overload Relay?

The TI-2 overload relays were used in DC motor circuits. This relay was a thermal magnetic device that provided inverse time and instantaneous trip characteristics. We no longer have a single device that can provide both inverse time and instantaneous trip operation.

The function can be duplicated with two separate devices (one time trip & one instantaneous) using our type C304 DC magnetic overloads. See attached catalog pages 69 thru 71.

The replacement relays are selected from tables 121 and 122 using the full load motor current for the specific application.

If only a single relay is to be used, the common practice it to utilize a Time Trip relay only.
