BMC Contactor Insulation Barrier
The BMC contactor insulation barrier is compression moulded bulk moulding compound, fitted inside low voltage contactor housings. It separates adjacent contact groups and keeps electric arcs from jumping across live components each time the contact breaks or closes under operating current.
When contactors switch loads repeatedly, local heat builds up around contact points. This BMC contactor insulation barrier keeps its shape and insulating boundary without softening or creeping. The compact moulded matrix resists carbonised tracking paths that slowly form on insulating surfaces after thousands of switching operations.
Every outline, cutout and positioning shoulder can be adjusted to match the internal layout of different contactor frames. Material samples pulled from each production run go through dry arc resistance and dielectric withstand checks before parts are cleared for shipment. These barriers are widely fitted into contactors used to start pumps, conveyors and other industrial machinery in factory control setups.
