XT2H 160 TMA breaker: trip-unit range, frame rating and protection coordination

ABB identifies catalog number 1SDA067604R1 as an XT2H 160 TMA 160-1600 three-pole fixed breaker with front terminals. The manufacturer’s catalog gives a 160 A rating and 690 V rated voltage for this entry. The designation string includes release information that must be read with the technical data; do not confuse a frame value, trip range and instantaneous setting as interchangeable ratings.

Key technical data

The values above are intended to identify the listed version and support an initial technical review. Confirm applicable standards, rating conditions, installed accessories and the current ABB documentation for the serial number or revision before design approval, replacement or commissioning.

Application and engineering focus

Use the breaker in a protection design that has been checked for load current, conductor ampacity, prospective fault current and selectivity. The TMA release combines thermal and magnetic protection. Verify the adjustment range and trip behavior for the exact release, then coordinate with upstream/downstream devices and the protected equipment. The XT2H interruption class identifies a product family performance class; fault capacity at a particular voltage must be taken from the ABB table.

Configuration, compatibility and related references

Confirm terminal orientation, fixed mounting arrangement, pole count and front-terminal wiring. Check auxiliary contacts, shunt trip, undervoltage release, motor operator and other accessories independently; they are not inferred from the base code. Nearby XT2 and XT4 breaker types can have different frame, trip unit and interruption values. Use the full catalog number and project short-circuit study when evaluating a substitute.

The related designations below are comparison references, not automatic substitutes. Confirm the complete type code, order number, interface, ratings and revision against the approved application before selecting an alternative.

Installation and commissioning checks

Before installation, isolate all sources and verify absence of voltage. Mount and torque conductors to ABB instructions, maintain required clearances and inspect the operating mechanism. Set the trip unit to the approved coordination study rather than copying settings from a similar panel. After installation, perform the required functional checks and document the protective-device settings, accessory list and circuit identification.

During commissioning, verify the nameplate, configuration, wiring and diagnostics before enabling normal operation. Test the relevant signal path or protection response end to end under controlled conditions. Record settings and as-left measurements, and investigate abnormal values at the sensor, load, wiring or system configuration before replacing components.

Ordering, replacement and application information

For a quotation or replacement review, provide the complete designation 1SDA067604R1XT2H 160 TMA 160-1600 3P F F, ABB order code where available, serial or hardware revision, quantity, installation environment, connected equipment, interface requirements and target delivery date. Include a clear rating-label photograph and relevant wiring, loop or panel drawing when possible.

Ask the supplier to confirm the exact configuration, accessories, revision and any approved successor in writing. Do not select solely from a family name or product photograph. For safety, grid-protection, medium-voltage or regulated applications, obtain review by the responsible qualified engineer and follow local codes and the manufacturer’s instructions.
