Description
LC terminal blocks can be used to convert standard connections into Faston connections: 2 x 6.3 mm or 4 x 2.8 mm per
pole. The connections are protected against accidental contact.
The LC30-T has a terminal block for the 3 power terminals and a second for the 4 auxiliary terminals of a TA25 DU
thermal O/L relay.
The LC26-B1 has two identical terminal blocks each for 3 power terminals. This block allows the power terminals to be
mounted with two DB25 kits or a TA25DU thermal O/L relay and DB25 kit assembly.
NOTE: According to DIN 46429 part 1 and NFC 20-120 the max. capacity of a Faston connection is 25 A.

Application
• The DS25-A coil is used for remote electrical tripping of the TA25 DU thermal O/L relay and is connected to the relay's
normally closed 95-96 auxiliary contact.
• The DR 25-A coil is used for remote electrical resetting of the TA25DU thermal O/L relay which is
adjusted for "Manual resetting"; it is connected to the relay's normally open 97-98 auxiliary contact.
The coils are not designed for continuous duty. Impulse duration: 0.2 to 0.35 s.
Set the button to "Man" (Manual resetting).
Mounting: clipped on to TA25DU thermal O/L relay.
