XT2S 160 TMD/1SDA067551R1: XT2S 160 TMD breaker selection: trip setting, terminals and coordination
The ABB XT2S 160 TMD, order code 1SDA067551R1, is a fixed three-pole Tmax XT molded-case circuit breaker with front terminals and a thermal-magnetic TMD release. ABB’s product listing identifies a 160 A frame, 20–300 A release designation and a 14–20 A setting range for this exact code. Breaking-capacity values depend on voltage and standard and must be checked on the nameplate and coordination documentation.

The table summarizes family or catalog values for identification and initial selection. Confirm the nameplate, environmental limits, standards, revision and options for the exact device before procurement or engineering approval.
Application and system selection
Select an MCCB against the circuit’s load current, prospective short-circuit current, selectivity requirement and protection philosophy. Confirm whether the application needs motor protection, cable protection or system isolation; the XT2S release selection and settings must fit the actual circuit. Consider accessories, enclosure and terminal direction as part of the panel assembly.
Configuration and compatibility
Check the breaker order code, pole count, release family, setting range, front/rear terminal arrangement and accessory compatibility. Compare Icu/Ics at the actual operating voltage and installation standard. Do not confuse frame current with the release setting or assume a same-frame breaker has equivalent protection behavior.

Installation and commissioning
Install only after isolating the bus and verifying absence of voltage. Mount with the specified orientation and terminal clearances, torque all connections to ABB values, and confirm insulation and protective-earth continuity. Set the thermal release, perform functional tests and verify coordination with upstream and downstream devices before energizing.
Replacement and procurement information
For a quotation or replacement review, provide the complete designation XT2S 160 TMD/1SDA067551R1, the order code where applicable, serial or hardware revision, quantity, operating environment, connected equipment and required delivery date. Include a legible nameplate image and relevant wiring, loop or switchgear drawing so the exact interface and configuration can be checked.
Ask the supplier to confirm accessories, revision compatibility and any approved successor in writing. Do not select solely from a family name or product photograph. Follow the current ABB installation and safety instructions for the exact unit.
