System compatibility
Specify F202 A-25/0.03 for a circuit where Type A residual-current detection and 30 mA additional protection are appropriate under the applicable electrical code. Confirm the protected circuit type, expected leakage, upstream/downstream selectivity and installation jurisdiction. Choose the device with its companion overcurrent protective device as a coordinated assembly.
Check rated current, number of poles, rated residual current, Type A suitability, line/load orientation and supply arrangement. Confirm that the connected equipment's waveform and leakage characteristics are within the device's intended application. ABB F202 A-25/0.03 must be coordinated with the upstream protective device and the required disconnection time.
Before replacement, compare F202 A-25/0.03 with the installed revision, accessories, wiring and engineering configuration.
Installation and acceptance
Isolate the distribution board and verify absence of voltage before installing F202 A-25/0.03. Wire neutral and phase conductors through the intended poles, maintain downstream neutral separation and torque terminals as instructed. Perform the prescribed test-button and instrument trip-time checks, record results, and verify that downstream overcurrent protection remains in place.
Acceptance check: verify the functional response and diagnostics for F202 A-25/0.03 against the approved schematic, control narrative and current ABB instructions. Record test results, final settings and any deviation before handover.
Keep the verified order information for F202 A-25/0.03 with the panel drawing, commissioning record and maintenance history.
