NOTES
1. The upper limit of safety temperature is 180℃, and the upper limit of functional temperature is 150℃
2. If the product needs to work for a long time, it is recommended that the upper limit temperature should not exceed 150℃. If the safety temperature exceeds 180℃, the electrical appliance may also catch fire
3. Ambient temperature is 85℃, wire cross sectional area ≥70mm² - (Test conditions for this curve)
4. The data greater than 2000A is the data of short circuit resistance of relay. The relay can guarantee no fire or explosion within this curve. When the current is greater than 3000A, the relay contact may be repulsed by a large current.
Mounting Attention
1. In principle, please do not use it when the relay has fallen down.
2. The relay contacts are sealed and filled with gas. When the contact temperature changes, there is internal gas penetrating characteristic. Relays are forbidden to be used at the temperature beyond our suggestion -40 ℃～85 ℃ for long time.
3. When installing the relay, always use washers to prevent the screws from loosening.
4. Tighten each screw within the rated range given in the outline dimensions. Exceeding the maximum torque may result in breakage.
5. Avoid mounting the relay in strong magnetic fields (near a transformer or magnet) or close to an object that radiates heat.
Electrical Life Attention
1. This relay is a DC high-voltage switch. In its final breakdown mode, it may lose the ability to provide the proper cut-off. Therefore, do not exceed the indicated switching capacity and life.
2. Please treat the relay as a product with limited life and replace it when necessary.
3. The contacts of the relay are polarized. Please follow instructions in the connection schematic when connecting the contacts.
4. Be careful that foreign matter and oils and fats kind, don’t stick to the main terminal parts because it is likely to cause terminal parts to give off unusual heat. Also, please use the following specifications of conductor.

Coil 200A type Attention
1. Please note that when using a diode, the switching speed may decrease and cause a reduction in cut-off performance, we recommend installing a surge protector varistor.
2. The pick-up voltage and drop-out voltage will change with ambient temperature, please use rated voltage to make sure the relay operate reliable. Don’t exceed maximum coil voltage.
3. Please do not continuously load the maximum voltage on the coil.
Coil 250A and 300A type Attention
4. The 250A and 300A types have built-in dedicated drive circuit, please drive the coil with a quick startup (Built-in one-shot pulse generator circuit).
5. After the ON signal enters the 250A and 300A types, automatic coil current switching occurs after approximately 0.1 seconds.Do not repeatedly turn it OFF within that 0.1seconds interval, as doing so may damage the relay.
