Modular Contactor BCH8-25 2P 2NO 25A

Modular Contactors BCH8 2P 16A 25A AC/DC

Denor Modular Contactors BCH8 used for commutation of single-phase and three-phase low power electrical consumers. They can be combined with auxiliary control, protection and indication functions; can be used to remote control applications in alternative networks: Lighting, heating ventilation roller blinds, sanitary hot water; mechanical ventilation systems; load-shedding of non-priority circuits, etc.

FUNCTIONS:

• switching on of consumers
• making of control systems
• remarkable with high reliability of current characteristics
• reliable switching on or separation of power contacts

 

TECHNICAL DATA:

• comply with standards IEC/EN 61095 standards IEC/EN 60947-4-1

Operation( Manual Control Contactors )

 

Manually-operated contactors have a 4-position selector switch on their front face:
• shutdown
• automatic operating mode
• temporary “ON” override
• permanent “ON” override: used to lock the contactor in the ON position during installation maintenance

Operation Manual control Contactors
