Lambda

Lambda type resistors are a type of Open wire wound Brake Resistors (OBR).  They are especially suitable for customer specified constructions with specific demands to mechanical sizes. The resistors are supplied as single components or as stacked resistor banks.  The resistors have protection class IP00, but we can supply Lambda resistors mounted in housings with protection class IP20 up to IP23.

The resistor wire is wound around special ceramic insulators with grooves keeping the wire in the right position. Metal plates support the insulators as shown on the drawings below.
For higher insulation levels, than specified in this data sheets, the supporting metal plates are insulated with ceramic insulators.  The resistors have solid terminals with screw holes for M5 screw connection.  The terminals are connected to the resistor wire by either welding or screw connection.
