摘要： The electromagnetic contactor enables a reliable return to a pole open position without increasing the spring force of a return spring. In an electromagnetic contactor, an electromagnetic device having an exciting coil and a contact mechanism having a return spring are disposed in parallel, and the electromagnetic device and contact mechanism are linked by a drive lever. The electromagnetic device has a polarized electromagnet having a magnetic circuit that includes a permanent magnet generating a suction force that moves the contact mechanism to a pole open position side when the exciting coil is not energized. The drive lever is fixed to either one of the electromagnetic device or contact mechanism and contacts with the other with no gap at least when the contact mechanism is moved to the pole open position side. The return force of the contact mechanism is covered by the suction force of the permanent magnet.

摘要： A thermal overload relay is formed of a case for retaining the relay and having an insertion hole, an adjusting device for adjusting a working current of the relay and situated inside the insertion hole, and a cover for covering the adjusting device and situated in the insertion hole. The case includes a first coupling device formed around the insertion hole. The cover is formed of a transparent plate and includes a smooth upper surface, a second coupling device formed on a side surface and engageable with the first coupling device, and a handle formed on the upper surface of the cover for handling the cover. When the cover is disposed in the insertion hole, the first and second coupling devices are engaged, wherein the upper surface of the cover is located below an upper surface of the case. The cover can be fixed to the case such that the cover can be removed from the case or permanently fixed to the case.
摘要翻译：热过载继电器由用于保持继电器并具有插入孔的壳体形成，用于调节继电器的工作电流并位于插入孔内的调节装置，以及用于覆盖调节装置并位于插入件中的盖孔。壳体包括围绕插入孔形成的第一联接装置。盖由透明板形成，包括平滑的上表面，形成在侧表面上并与第一联接装置接合的第二联接装置，以及形成在盖的上表面上用于处理盖的手柄。当盖布置在插入孔中时，第一和第二联接装置接合，其中盖的上表面位于壳体的上表面下方。盖可以固定到壳体上，使得盖可以从壳体移除或永久地固定到壳体上。
