Allen-Bradley has been Rockwell Automation's industrial control brand name since Rockwell's 1985 acquisition of the company — old enough that a lot of what still needs replacing on live panels today predates most of the engineers currently maintaining it. Z & F Corporation Ltd supplies 480 genuine Allen-Bradley lines, overwhelmingly contactors and the relays that protect them.
What You'll Find
- Contactors — the 100-C, 100-E, and 100K series, from small control-relay-sized units up to 400A frames.
- Thermal overload relays — the 193 series, sized to match a specific contactor frame and motor full-load current.
- Auxiliary contacts & accessories — add-on contact blocks, terminal shrouds, and mounting accessories for building out a contactor assembly.
- Solid state relays — the 156-C series, for switching duty without mechanical contacts.
A contactor's coil voltage, pole count, and current or kW rating are non-negotiable specifics — get one of them wrong and it's not a close fit, it's the wrong part. The series designation printed on the contactor (100-C, 100-E, etc.) narrows things down fast; the coil voltage and NO/NC auxiliary contact configuration usually finish the job.
Matching an Overload Relay to Its Contactor
A 193-series overload relay has to match both the contactor frame it mounts to and the motor's full-load current (F.L.C.) it's protecting — not just one or the other. Send us the contactor model and the motor nameplate current and we'll confirm the correct overload relay.
We are not Rockwell Automation, and not an authorised Allen-Bradley distributor — we source and supply genuine stock independently, with any distribution disclosure noted on the relevant product page. Orders ship worldwide with export documentation as standard; panel builders and maintenance contractors across the Gulf, Pakistan, and East Africa are regular customers for this range alongside the UK.
Frequently Asked Questions
Can you match a contactor by its series number alone?
It narrows things down significantly, but coil voltage and pole/current rating are also needed to confirm the exact part or a genuine equivalent.
Do you supply the overload relay matched to a specific contactor?
Yes — send us the contactor model and the motor's full-load current and we'll confirm the correct 193-series overload relay to pair with it.
Can you supply older Allen-Bradley series that have since been redesigned?
In many cases yes — we source through multiple channels and can often find remaining genuine stock or a direct current-production equivalent.
