1SDA078012R1 E4.2S-A 3200 EKIP TOUCH LSI 3P FVR: E4.2S-A 3200 breaker: trip-unit, switchgear and rating verification
The supplied designation identifies an ABB SACE Emax 2 E4.2S-A 3200 air circuit breaker fitted with an Ekip Touch LSI trip unit in a three-pole FVR configuration. The code indicates a high-current breaker frame and electronic long-, short- and instantaneous-protection functions, but it does not alone establish the complete interrupting rating or switchgear compatibility.

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
Emax 2 selection requires a protection study covering system voltage, prospective short-circuit current, continuous current, selectivity and the installation’s neutral and earthing arrangement. Review the trip-unit settings, sensor rating, communication modules and service-access method. This is a low-voltage power circuit breaker; commissioning and maintenance belong to qualified switchgear personnel.
Configuration and compatibility
Confirm the full catalog number, fixed or withdrawable execution, terminal orientation, accessories, interlocks and control supply. Check that the trip unit, rating plug and sensor configuration match the protection coordination study. Mechanical dimensions and cassette interfaces must be checked against the exact panel design; family names do not guarantee interchangeability.

Installation and commissioning
Apply lockout/tagout, verify absence of voltage and discharge stored-energy mechanisms before work. Inspect primary connections, shutters, interlocks, racking position and trip-unit configuration. Perform the manufacturer-prescribed primary or secondary injection and functional checks, record the settings and test results, and obtain approval before energizing.
Replacement and procurement information
For a quotation or replacement review, provide the complete designation 1SDA078012R1 E4.2S-A 3200 EKIP TOUCH LSI 3P FVR, 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.
