Choosing SSM1D26BD Harmony modular solid-state relay for an installed system
Use the full SSM1D26BD designation when discussing this Harmony modular solid-state relay with a supplier or engineer. The Schneider category main image is a shared reference collage, not an exact photo of SSM1D26BD. The table records limited confirmed facts; the site-specific decision requires the current product document and installed-system information.

Where the item fits
The selection question for SSM1D26BD is not simply whether the code looks familiar. Identify its actual role as Harmony modular solid-state relay, the equipment it connects to, and the site operating conditions. Check load type, thermal derating and control signal. Record any missing interface value as a question to verify rather than filling it from a neighboring model.
Keep SSM1D26BD in the equipment schedule with the intended host, panel or circuit. A shared product picture can show the general category, but it cannot verify terminal layout, voltage, current, firmware or mechanical dimensions of the delivered SSM1D26BD.
Mating and integration checks
Before ordering SSM1D26BD, compare electrical supply, protection, signals or communication settings where relevant. Confirm mechanical installation, mating connector and accessory dependencies. If an engineering drawing refers to another code, obtain an approved cross-reference before substituting SSM1D26BD.
For maintenance replacement, capture the original nameplate and any revision label. Compare the complete string with SSM1D26BD; a changed suffix can alter a component's function. Review thermal, environmental and safety limits with the manufacturer's exact documentation, not with a general family image.
Quotation and receiving controls
Ask for an offer naming SSM1D26BD exactly, with quantity, destination, lead time and current data sheet. Clarify whether a cable, fuse, mounting part, software or other accessory is included. If SSM1D26BD is discontinued, ask for a documented alternative and evaluate its differences before purchase.
When SSM1D26BD arrives, inspect package condition and label. Confirm that the full marking matches the approved order, photograph it and record the supplier's reference. Quarantine a unit labelled differently from SSM1D26BD until the substitution has been reviewed.
Installation and acceptance
Install SSM1D26BD under the applicable safe-isolation and manufacturer's instructions. Record relevant setting values, wiring, mounting and connected equipment. A functional test should demonstrate the intended role of SSM1D26BD without relying on code appearance alone.
Retain the final SSM1D26BD designation, the tested configuration and the location in the maintenance record. This allows a later buyer to distinguish the installed item from a similar-looking spare. Any change from SSM1D26BD should remain traceable to engineering approval.
Look-alike catalogue references
These 1 designations resemble the SSM1D pattern of SSM1D26BD and are indexed here for search. Similarity does not establish that they have the same function, rating, connection or approvals. Check each complete code separately before treating it as an option for SSM1D26BD.
Selection conclusion
Approve SSM1D26BD only when the verified product facts, installation interface and quotation agree. Keep the complete SSM1D26BD phrase in the purchase order and acceptance record; do not treat a near-looking designation as interchangeable without manufacturer and engineering evidence.
