BHL TYPE DISCREPANCY SWITCH (NEW TYPE)

BHL TYPE DISCREPANCY SWITCH

FEATURES

  1. With the rolling action of the contact mechanism that minimizes the area exposed to arc, improved contact stability can be maintained for a long period.
  2. The optimum design of cam shape and moving contact angle can improve the breaking capacity, enabling voltage and current value settings with a certain margin.
  3. Round and square types of nameplates can be selected.
    Indication can be differentiated by the shape of nameplate, resulting in a panel design improvement.
  4. Variations in lamp circuit voltage (24 V, 48 V, 110 V, 125 V and 220 V)
  5. A LED lamp type with built-in flicker circuit is available. With this type, the knob can be flickered.
    * For the indication method, refer to “LXF” in the table (7) on F59.
  6. The key lock mechanism can prevents erroneous operation.
    A cylinder type (BHLC type) key and padlock type (BHLP type) key are available.
  7. The back terminal type (BHL-B type) enables quick wiring.
  8. A BHLFX type that conforms to the IP40 enclosure rating is available.
    Since the knob is fastened with a screw, the BHLF type can prevent entry of external foreign objects and accidental contact with live parts.
    A protective ground terminal is also provided.
