  • International standards approval.
    Conform IEC, BS, DIN and VDE standard (H65C to H800C). Adapt to CE-Marking (H65C to H125C)
  • Applicable to use for crane and hoist due to shorten breaking time of contactors.

Color indicator for the operation

  • New color - indicators enable certain discrimination of moving
  • Contactors
  • Color of Indicator changes from green to red after the contactor is closed.(H65C - H800C)
  • Thermal overload relays
  • Color of indicator changes from black to yellow if the thermal overload relay (All models) was tripped.

High safety

  • New preventive mechanism for mal-operation, phase separator, etc.

Preventive mechanism of careless operation

Thermal overload relays
"Cover" prevents the touch to release test lever. (All models)

Thermal overload relays

Sequence check rod will be operated when the indicator is opened. (H65C - H800C)



Free arc space


Phase separator

  • Additional phase separator. (H80C - H800C)
    Phase separators will be attached to the contactor.

Mechanical interlock

  • (Reversible type : over H20) Mechanical interlock is also attached to reversible contactor.

Safety cover (option)

  • Easy attachment. (H8C - H800C)
    Live parts will be covered by safety cover, and it improves safety.

High Reliability

  • Highly reliable contacts enable direct connection to the electronic circuits.
    Auxiliary contacts of contactors
  • Rolling twin contacts assure high contact reliability. (All models)
    Rolling twin contact

Signal contacts of thermal overload relays

  • Signal contacts of thermal overload relay are 1NO 1NC. (All models)
Signal contacts


Auxiliary contact block (H20 - H400C)

Rolling twin contact


Coil surge absorber

Coil surge absorber

Coil surge absorber will be installed by "Single Snap Action". (H8C - H125C), and H150C and above, it is constructed in coil assembly.

Easy maintenance and inspection

  • Quick contact inspection
    Access to contacts is done by unfastening two screws and removing the cover.
  • Easy contact replacement
    Contact can be removed / replaced by single snap action without taking off the contact spring. (H80C - H400C)



Easy wiring

Easy wiring

  • Adoption of washer-based self-up screw.
    Main terminal screw : up to H50.
    Operation terminal screw : all models.
  • Flat terminals built-in rugged studs facilitate connection of wires with a single spanner. (H100C - H600C)

DIN rail mounting mechanism

  • H8C - H50 are available DIN rail mounting.
