About TeSys Contactor Auxiliary Blocks and Coil Modules

These are the parts that clip onto a contactor rather than replace it, and the prefix tells you where they mount. LAD references are the front and side accessories for the TeSys D frame: instantaneous auxiliary contact blocks, on-delay and off-delay timing blocks, and mechanical latch and interlock kits. LA1 references are auxiliary blocks for the smaller K and E frames. LA4 references are coil-side modules — RC and varistor surge suppressors, and the interface modules that let a low-power controller output drive a contactor coil directly.

Two things decide whether an accessory is correct. The first is the frame: a block made for TeSys D does not fit TeSys K, and the two ranges are close enough in appearance that this is a genuine ordering trap. The second is the contact configuration, given as the number of normally-open and normally-closed contacts — an 11 block is one of each, a 20 block is two normally-open. Surge suppressors additionally have to match the coil voltage and type, because an RC network sized for an alternating-current coil is not what a direct-current coil needs.

TeSys Contactor Auxiliary Blocks and Coil Modules in Saudi Arabia

Auxiliary blocks are consumed steadily in Saudi motor control centres because they carry the control and interlock wiring rather than the motor current, and control circuits get rewired far more often than power circuits. A pump station that adds a duty-standby changeover, a conveyor that gains a run-status signal to a SCADA system, a starter modified during a plant upgrade — each of those needs contacts a contactor did not originally carry.

Surge suppressors deserve more attention than they usually get. A contactor coil switched by a controller output generates a voltage spike on de-energising, and over months that spike degrades the output transistor or relay in the controller. The failure looks like a controller fault rather than a wiring omission, which is why it is often diagnosed late and expensively. Fitting the suppressor at build time costs very little; retrofitting it after an output card has failed costs a great deal more, and on a plant with frequent start-stop duty the exposure is continuous.

Ordering and lead time

Tell us the contactor the accessory mounts on, not just the accessory reference. The frame is what decides fit, and TeSys D, K, E and F take different blocks despite looking similar on a rail. If you are unsure of the frame, the reference on the front of the contactor gives it to us.

For auxiliary blocks, state the contact configuration you need — how many normally-open and how many normally-closed — and whether the block mounts on the front or the side, since side mounting is limited by what is already fitted. For surge suppressors and interface modules, state the coil voltage and whether it is alternating or direct current, because the module must match the coil rather than the supply. Typical lead time is three weeks from order confirmation. Items are supplied to order and delivered duty-paid, with import and customs clearance handled by us.
