Precautions for Use
Please follow these precautions when using the C8P-60A to ensure long-term safety and performance:
Mechanical Installation
-
Always use flat and spring washers during installation to prevent loosening.
-
Maximum pulling/pushing force on terminals is:
– Load terminal: 49N
– Coil terminal: 49N
Exceeding these values may cause mechanical damage.
Soldering
-
Manual Soldering: 380 ± 20°C for 3–5 seconds
-
Wave Soldering: 265 ± 5°C for 3–5 seconds
Surge and Capacitive Load Protection
-
For inductive loads (L/R ≥1ms), always use surge absorbers such as varistors or TVS diodes.
-
For capacitive loads, use a pre-charge circuit and control the closing voltage difference to ≤20V to prevent contact welding.
-
For products without an economizer, do not use a diode for coil suppression; instead, use TVS or varistor.
Environmental Conditions
-
Use within -40°C to +85°C. Do not exceed this range, as internal gas pressure may rise and affect reliability.
-
Avoid installing near heating elements (e.g., fuses, shunts) to prevent overheating of contact ends.
-
Avoid installation near strong magnetic fields or near grease/contamination at terminals.
Handling & Storage
-
Do not reuse the contactor if it has been dropped.
-
Store in a dry place, avoiding direct sunlight and corrosive gases.
-
Storage Life: 12 months in original packaging.
