HFEVC-TF300
Product Features
- Ceramic vacuum brazing seal is adopted to ensure no arc leakage, and the contact point can meet the protection grade of IP6K9K.
- The mixed gas mainly filled with hydrogen can quickly cool the arc and prevent the contact from oxidation and burning.
- 300A 85°Clong time current carrying capacity.
- The rated voltage of cut-off load is 12-750VDC.
- The insulation resistance reaches 1000m Ω (1000VDC) and meets the requirements of IEC 60664-1.
- Energy saving type: control by Double coil PCB board ,when at low power consumption, product can keep in incentive condition.

Precautions For Use
1. To prevent looseness, use a gasket when installing the contactor. Please use M5 screw at contactor installation. Screw locking torque should be controlled within 3N·m~4N·m; The screw locking torque at the installation of the leading end should be controlled at 9N·m~11N·m. In case of exceeding the range, it may cause damage.
2. Avoid sticking grease and other foreign bodies on the leading-out piece, and use the connection wire of 100mm² or above, otherwise abnormal heating may be caused at the leading-out end.
3. The product is built with an energy-saving board. The coil will switch after 0.2s is driven, but the repeated on/off operation < 0.2s will cause contactor failure.
4. The product with built-in circuit board cannot be driven by slow rising voltage. Please drive the coil by fast rising edge (step power supply mode), otherwise it won’t move!
5. It is recommended that the thickness of copper strip be 3mm, otherwise it will cause the problem of thread sliding teeth or loose installation.
