Current Endurance Curve
Notes:
1) The ambient temperature is 85℃, and the cross-sectional area of the copper bar is ≥100mm². Supply rated voltage to coil;
2) The upper limit of the function temperature is 130℃, which is suitable for long-time working; and the upper limit of the safe temperature is 180℃, which is suitable for short-time working; If the temperature exceeds 180℃,the contactor may fail;
3) When working at 2500～8000A, the contactor’s contacts will not be repelled, and the matching fuse should be blown in time, the contactor may stick, but it will not fire or explode;
4) The contactor’s contacts may be repelled when the current is greater than 8000A, if the fuse does not blow
in time, the contactor may catch fire or explode.

注 Notes：
1) 由于本产品静触头为纯铜材质，如贮存时间较长，使用前应检查触点表面氧化程度，如已发生氧化变色，应当对触点表面进行打磨去除氧化层再使用。贮存环境应避免凝露、结冰。
Since the fixed contact of this product is made of pure copper, if the storage time is longer, the oxidation degree of the contact surface should be checked before use. If oxidation discoloration has occurred, the surface of the contact should be polished to remove the oxide layer before use.The storage environment should avoid condensation and icing.
2) 如贮存时间超过3个月，使用前应重新对接触器进行参数检测。
If the storage time exceeds 3 months, the parameters of the contactor should be tested again before use.
3) 当海拔超过2000m时，应根据《IEC 60947-1》要求降容使用。
When the altitude exceeds 2000m, it should be used with reduced capacity according to the requirements of IEC 60947-1.

其他说明 Others
1. 请避免触点附着异物、油脂类及腐蚀性液体，否则会导致发热异常。
Please avoid foreign bodies, grease or corrosive liquids in the terminal, otherwise it will lead to abnormal heating at contact terminals.
2. 请避免在强磁界（变压器、磁铁的周围）和发热物体的附近安装。
Please avoid installation in strong magnetic field (around the transformers, the magnet) and the heating objects nearby.
3. 防止出现松动，接触器安装时请使用垫圈。接触器安装处请使用 M5螺钉，螺钉锁紧扭矩请控制在 3 N·m～4 N·m；在超过范围的情况下，可能会造成破损。
In order to prevent loosening, please use the washer when installing the relay. Please use the M5 screws to install relay, screw locking torque within 3 N·m～4N·m; Damage may occur when it is beyond the range.
4. 注意连接铜排的厚度和扭矩大小，若超出下表建议的数值，会造成螺纹牙或安装不紧的问题；不建议将两铜排安装在同一侧，避免高压短路或打火。
Please pay attention to the thickness of copper bars and the value of the torque. If it goes beyond the recommended values in the below table , it will cause thread slide or installation is not tight. To avoid short circuit or fire,it’s not suggest fix two copper bus bar at same side.

5. 触点额定值均为阻性负载时的数值，使用 L/R≥1 ms 的感性负载（L 负载）的情况下，请与感性负载并行采取浪涌吸收措施。未采取措施的情况下，可能会造成电气寿命下降、发生切断不良。
The rating load of contact is resistive load. Please assure the surge absorption device together with inductive load when using the L/R≥1 ms inductive load (L Load),otherwise it may lead to the decrease of electrical endurance and defective switch.
6. 本继电器的内部触点使用了气体保护，伴随着触点温度变化（环境温度+通电致使温度上升）而存在内部气体穿透，严禁将继电器长时间置于超过产品温度使用范围（-40℃～85℃）环境中。
The relay contacts are sealed and filled with gas. When the contact temperature changes, there is internal gas penetrating characteristic.Neputune relays are forbidden to be used at the temperature beyond our suggestion -40 ℃～85 ℃ for long time.
7. 在继电器坠落的情况下，原则上请不要再使用。
In principle, please do not use it when the relay has fallen down.
8. 尼普顿产品均符合RoHS2.0要求。
Neptune products are all RoHS2.0 compliant.
