∆ Contactor mounting requires the use of a bus bar mounting kit (Cat. Nos. 825-MVS or 825-MVS2).

‡ 0.5…20 A can be achieved by looping the motor supply cables. (Refer to the Specifications on Test Button for Thermal Overload Protection
Pressing the test button will verify thermal tripping operation time at 6x/e without the motor being connected. The test button must be held for longer than the set trip time t6x/e.

Supply Voltage Failure

In the event of a supply voltage failure, the output relay resets and the stand-by indicator goes out. The actual status is stored for 30 minutes. When the supply voltage
is restored, the output relay reverts to its original state.

Reset — Manual
The reset button resets all protection functions. Resetting from any location is possible with the 193-RB1 remote reset module.

Reset — Automatic
Automatic resetting of thermal overload and thermistor overtemperature functions is an optional feature. All other protection functions must be reset manually.

Test Button for Thermal Overload Protection

Pressing the test button will verify thermal tripping operation time at 6x/e without the motor being connected. The test button must be held for longer than the set trip
time t6x/e.

Setting the Rated Current (0.5…20 A) (193­EF1A and 193­EF2A Requires 193­HD)

The motor supply cables are looped through the current transformer twice, thereby doubling the rated motor current. The setting on the Bulletin 193-EF overload relay is
the product of:
