How should the quote be checked?
Ask for the current data sheet and installation document for RHK412M. Check lead time, regional availability, accessory inclusion and documented status. If the manufacturer offers an alternative to RHK412M, compare the interface and safety consequences before authorising it.
What happens at receiving?
Compare the delivered RHK412M label with the approved order. Photograph the marking, inspect the packaging and terminals, and record any missing parts. Keep a traceable receiving record so RHK412M cannot be confused with a near-looking stock item.
What should commissioning record?
Install RHK412M under the relevant isolation and manufacturer instructions. Record the equipment tag and the applicable functional test, whether it concerns power, switching, communications, movement, signalling or measurement. A change away from RHK412M should be reviewed before energisation.
What is being ordered?
Specify RHK412M without dropping punctuation or suffixes. The product identity is Harmony RHK latching plug-in relay; identify the quantity, destination country, revision needs and accessories in the enquiry. A supplier quotation that substitutes a different code for RHK412M requires a written cross-reference.
What should match on site?
Record the installed host, supply, load and mechanical interface before accepting RHK412M. Match socket, coil and contact duty. Compare the exact label and data sheet for RHK412M with the approved installation drawing. The verified table is a starting point, not a full engineering approval.
Which parameters can vary?
The exact RHK412M marking matters because similar codes can identify other ratings, options or roles. Do not transfer a voltage, current, contact arrangement, ingress rating or protocol from another designation to RHK412M. Where the table gives a family-level description, confirm the unit-specific value on the manufacturer's current document.
Other visually similar designations
No additional unassigned RHK-pattern code is indexed under RHK412M. A code that merely looks related still needs its own identification check.
Final selection note
For RHK412M, make the final decision from the exact current manufacturer documentation and the specific site interface. Keep the selected RHK412M designation in the purchase order, receiving check and maintenance record.
