Features:
- Latched operation: Retains its operated state for deliberate hand or electrical reset.
- Contact duty: Provides multiple contacts for tripping, interlocking, and indication circuits.
- Scheme controls: Supports reset inhibition through the documented external link arrangement.
The full order code defines the relay beyond the MVAJ105 family designation.
Operate and reset wiring should be considered together because both interact with the latched mechanism.
Commissioning should prove every contact actually assigned in the protection scheme.
Apter Power supports MVAJ105RA0802A quotations, official documents, and protection-circuit review.

- Operate path: Confirm the energising circuit and terminal allocation against the scheme drawing.
- Latch action: Verify the armature holds the commanded state after the initiating signal clears.
- Flag: Check that the mechanical indication follows the operated mechanism.
- Burden control: Retain the documented cut-off arrangement rather than altering internal links casually.
- Manual reset: Prove the front control releases the latch without contact binding.
- Electrical reset: Confirm the reset command reaches the correct coil and terminals.
- Inhibitor link: Keep the external link setting consistent with the approved protection design.
- Assignment: Map every used make and break contact to its field function.
- Continuity: Measure the normal and operated states before connecting the trip circuit.
- Timing: Confirm auxiliary actions occur in the required protection sequence.
- Final proof: Archive trip, indication, interlock, and reset results together.
- Trip circuits: Provides latched contacts for protection and breaker-control schemes.
- Alarm retention: Maintains a visible operated state until authorised reset.
- Interlocking: Supports multiple auxiliary paths where deliberate reset is required.
