Data record instr.circuit-breaker-analyzer.coil-current-signature

Verified 2026-10-27 Confidence: High

The trip and close coil currents are recorded against time: the current rises, drops when the armature begins to move and releases the latch, rises again when the armature reaches its end stop and is cut when the auxiliary contact opens, so a change in the trace points to latch, lubrication or control-voltage problems.
