Ghisalba GHMC.4.00 relay contactor
 |
GHMC.4.00 is a four‑pole mini contactor rated at 9 A/4 kW (AC‑3) with a 220‑230 VAC coil used in motor control panels and soft‑starter circuits. Common failure modes for this model include coil winding insulation breakdown, contact erosion or pitting from repeated switching, and arcing that can damage the contacts or generate heat. Initial diagnostics should verify the coil supply voltage and current draw against spec; perform a continuity test on the main contacts and auxiliary contacts to detect open circuits; visually inspect the housing and contacts for corrosion, burn marks, or mechanical wear before proceeding with deeper functional tests.[oss-gpt-20b] |
