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.
Device Installation and Commissioning
The operating instructions enclosed with the device provide all of the information necessary to set and commission it.
Surface Mounting
193-EF_A Snap-on fixing to standard DIN Rail or screw fixing
193-EF_B Screw fixing
193-EF_C Screw fixing
Mounting position: optional
Setting the Rated Current (0.5…20 A) (193-EF1A and 193-EF2A Requires 193-HD)
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:
Ie [A] x…number of loops
