How should the quote be checked?
Ask for the current data sheet and installation document for RSZL300. Check lead time, regional availability, accessory inclusion and documented status. If the manufacturer offers an alternative to RSZL300, compare the interface and safety consequences before authorising it.
What happens at receiving?
Compare the delivered RSZL300 label with the approved order. Photograph the marking, inspect the packaging and terminals, and record any missing parts. Keep a traceable receiving record so RSZL300 cannot be confused with a near-looking stock item.
What should commissioning record?
Install RSZL300 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 RSZL300 should be reviewed before energisation.
What is being ordered?
Specify RSZL300 without dropping punctuation or suffixes. The product identity is Harmony relay marking legend; identify the quantity, destination country, revision needs and accessories in the enquiry. A supplier quotation that substitutes a different code for RSZL300 requires a written cross-reference.
What should match on site?
Record the installed host, supply, load and mechanical interface before accepting RSZL300. Check the relay socket/holder and marking space. Compare the exact label and data sheet for RSZL300 with the approved installation drawing. The verified table is a starting point, not a full engineering approval.
Which parameters can vary?
The exact RSZL300 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 RSZL300. 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 RSZL-pattern code is indexed under RSZL300. A code that merely looks related still needs its own identification check.
Final selection note
For RSZL300, make the final decision from the exact current manufacturer documentation and the specific site interface. Keep the selected RSZL300 designation in the purchase order, receiving check and maintenance record.
