ABB LA1860 ABB Contactor Accessories

Razz Middle East supplies ABB contactor accessories in Saudi Arabia, sourced to order against the catalogue reference. These are the blocks and kits that clip onto a contactor to extend what it does: auxiliary contact blocks, timer blocks, coil surge suppressors, mechanical interlocks and mounting hardware. They are ordered separately from the contactor, quoted per part number and delivered duty-paid, with a typical lead time of three weeks.

About ABB Contactor Accessories

A contactor leaves the factory with a fixed set of power poles and, usually, a small number of built-in auxiliary contacts. Everything beyond that is an accessory. Front and side auxiliary contact blocks add the normally open and normally closed contacts a control circuit needs for interlocking, sealing-in a start command, or reporting the contactor's state to a PLC, and the maximum number that can be fitted is set by the contactor frame.

Timing blocks give a contactor an on-delay or off-delay function without a separate relay in the panel. Surge suppressors — RC networks, varistors or diode modules depending on whether the coil is AC or DC — clamp the voltage spike produced when the coil is de-energised, which protects the PLC output or the auxiliary contact that switched it. Mechanical interlock kits physically prevent two contactors from closing together, which is how a reversing starter or a source changeover is made safe without relying on control logic alone. Coil replacement kits, connection links for star-delta and reversing assemblies, and terminal covers complete the range.

ABB Contactor Accessories in Saudi Arabia

Accessories are ordered by the panel shop during a build and by maintenance afterwards, and in Saudi plants the second case dominates. Motor control centres in Jubail and Yanbu petrochemical plants hold hundreds of starters, and modifications — adding an interlock, feeding a status contact to a new PLC, adding a suppressor after a run of PLC output failures — are made on the existing contactors rather than by replacing them. Water and desalination sites use timer and interlock blocks on pump duty-standby arrangements and on manual mains-generator changeovers at remote well fields and lift stations. Cement, steel and food plants use reversing interlocks on conveyors, dampers and dosing screws. Heat inside an unventilated cubicle and fine dust are the usual reasons a coil or an auxiliary block fails first, and equipment on regulated projects is subject to SASO conformity on a 380/400 V, 60 Hz supply.

Ordering and lead time

Quote the accessory reference, for example LA1860, and tell us the contactor it has to fit — its full reference and its frame size. Accessories are frame-specific: a front block made for one frame will not latch onto another, and the number of blocks a contactor will accept is limited. For an auxiliary block, give the contact arrangement you need in normally open and normally closed terms. For a surge suppressor, give the coil voltage and say whether the coil is AC or DC. For an interlock kit, confirm whether the two contactors are side by side on the same rail or mounted one above the other. If you are working on an installed panel, a photograph of the contactor with its existing blocks is the quickest identification. Sourced to order, typical lead time three weeks, delivered duty-paid.
