All variants share the same ABB SNK / SNA screw-clamp terminal footprint and terminal layout; the columns above show where they differ. Selecting a different catalog number changes the electrical interface, not the mounting.
Where it sits in the control system
The 1SNA645512R2700 is the device-level element in an ABB terminal block installation. It receives the field signals and control supply listed above — 800 V (IEC 60947-7-1) — and switches or conditions the load within the up to 41 A (IEC 60947-7-1) ratings shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in control panels, machine builds, spare-part replacements, where the unit is matched to the original catalog number and the enclosure provides DIN rail / panel support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Before you specify
-
Ratings. Confirm the rated current and voltage match the circuit before specifying; sizing from the nameplate avoids field mismatch.
-
Mounting. Check the DIN rail / panel fit against the existing enclosure before ordering.
-
Marking. Record the catalog number and revision from the nameplate of the installed unit for a like-for-like spare.
Technical FAQ
Q.What supply does this device require?
It requires 800 V (IEC 60947-7-1). Size the supply source to the same rating shown in the Specifications table.
Q.What are the key electrical ratings?
The confirmed ratings include up to 41 A (IEC 60947-7-1) and CE, UL, CSA, CCC marking. Cross-check them against the installed unit's nameplate.
Q.How is this device mounted?
It mounts by DIN rail / panel. Confirm the cutout or rail before ordering a like-for-like spare.
Q.What is the operating temperature range?
The confirmed operating range is 0...+55 °C (IEC 60068-2-1). Panels running beyond it need derated sizing.
Q.What replaces a unit that is no longer in production?
For a like-for-like spare, record the catalog number and revision from the nameplate; a current-production equivalent is identified by matching function and ratings.
