A better brief.
A clearer offer.
Give suppliers the same requirements and record differences before choosing. Our role is to coordinate the agreed sourcing and purchasing work; final technical selection belongs with your appointed engineer.
See our quality-control scope ↗- Start with the motor and load
- Supply the motor nameplate, driven equipment, operating cycle, starting conditions and speed-control requirement. A kW figure alone leaves important details open.
- Define the control interface
- Confirm coil and control voltages, contact arrangement, input/output signals, communication requirements and required wiring diagrams.
- Compare complete assemblies
- For a starter, request a bill of materials and diagram. Identify protection, overload device, enclosure, controls and accessories included in the price.
- Confirm operating conditions
- State the ambient conditions, mounting space, enclosure, cooling and installation requirements. Ask the supplier to explain any proposed derating or additional equipment.
- Agree samples and support
- Record the approved model, settings or firmware where relevant, labels, manuals and spare-parts scope. Agree the functional checks and any application or commissioning support.
