How we handle panel components requests
One request, several lines
Panel jobs rarely need a single part. Paste your full parts list into the quote form and we will price the lot.
Built to the drawing
Send the schematic reference or the old part and we will match ratings, coil voltages and mounting.
About panel components from Precision Spares
Control panels are the operational heart of any automated plant, housing the components that distribute power, switch loads, protect circuits and interface between the field devices and the control system. When a panel component fails — a burnt-out contactor, a tripped circuit breaker or a failed 24 V DC power supply — the consequences ripple outward to every machine that panel serves. We supply a comprehensive range of control panel components to maintenance teams and panel builders across South Africa, helping keep production lines running and new installations on schedule.
The components inside a control panel must work together as a system: contactors sized correctly for the motor load, circuit breakers with the right tripping characteristic, power supplies with adequate current capacity for all the connected devices, and relays and terminal blocks that match the wiring schematic. Sourcing these components from a single supplier simplifies procurement, reduces the risk of mismatched parts and speeds up urgent repairs. We can quote your full bill of materials line by line, matching specifications from your schematic or from the failed component.
For emergency panel repairs, we understand that time is critical. Common contactors, circuit breakers, power supplies and interface relays are held in local stock for same-day or next-day courier delivery to your site. For larger panel build projects, we can source the complete component list and confirm lead times so your panel shop is not left waiting for parts. Whether you are replacing a single failed component or building a new panel from scratch, send us your requirements and we will respond with availability, pricing and delivery options tailored to your location in South Africa.
Common questions
Can I send a full bill of materials?
Yes. Paste it into the notes field or message it on WhatsApp and we will respond line by line.
What panel components do you supply most often?
Contactors, overload relays, circuit breakers, 24 V DC power supplies, interface relays, terminal blocks and push buttons.
How do I match a contactor to my application?
Motor power or current, coil voltage and the number of auxiliary contacts needed are what we match. Send the old contactor's rating or the motor details.
Can you supply 24 V DC power supplies?
Yes. DIN-rail power supplies in the common power ratings are a regular item. Tell us the current you need and we will confirm the size.
Do you stock items for urgent panel repairs?
Many common panel components are available locally for urgent requests. Mark the job urgent when you send it and we will prioritise the response.
Can you match a circuit breaker to replace a damaged one?
Yes. Send the rating, the number of poles and the tripping characteristic, or a photo of the existing breaker, and we will confirm the replacement.
What is the difference between a contactor and a relay?
A contactor is built for switching higher-power loads like motors, while a relay handles smaller control signals. The load type decides which is correct.
Do you supply terminal blocks and DIN-rail accessories?
Yes. Terminal blocks, end stops, markers and DIN-rail hardware are part of our range for repairs and new builds.
Can you help identify a component from a schematic reference?
Yes. Send the schematic or the reference on the drawing and we will advise on the correct part.
Do you supply push buttons, selector switches and pilot lights?
Yes. Operator devices for panels are a regular item. Send the colour, contact configuration and panel cut-out size and we will confirm.
Can you quote components for a whole new control panel?
Yes. Send your bill of materials or the schematic and we will price the components line by line.
