                         Yes, the old style front mount latch attachments, timing attachments, and auxiliary contacts will mount on the new Tesys D-line relays.

                        What is the replacement for a LA6DK10B

                         Part code is LAD6K10B

                        Why does my other equiptment trip when my contactor releases?

                        The colapsing coil voltage on DC is causing a Back EMF (electro magnetic field) issue. This is solved with either a varistor LA4SKE1E or a Diode LA4SKC1U on the LP1K09 contactor.
