![]() There is an exception to this, which is the Schuko plug where the earth connection is located on the side of the plug and made of metal contact surfaces. In all plug types, this earth connection was fitted as a 3rd pin. In order to provide safety, an earth connection had to be fitted to 2-pole plugs for these devices. In most countries in the world, 2-pole mains sockets have been replaced with earthed sockets which can accept both 2-pole and 3-pole plugs.ģ-pole means that the device plug is earthed and that it normally has three pins, of which two are used to transfer the current and one is used as personal protection.Īs previously mentioned above, due to the predominance of more powerful devices in the 1930s, (normally above around 500 watts), the problem of a possible electric shock became a hazard for users. In the case of less powerful devices (normally up to around 500 watts), 2-pole connections are still the norm since these can be produced more economically. ![]() This is due to the plug pins, which are often not thick enough to continuously resist the heat caused by the higher power. For example, if more than 2.5 amperes (in other words, more than 500 watts), are transferred through a 2-pole plug, it is possible that damage caused by smouldering or burning can occur under certain conditions. In addition, 2-pole plugs are not constructed to continuously withstand high currents. Earthed plug systems are therefore known as 3-pole systems, even though this is not quite technically correct. This problem was solved by introducing an earth connection, mainly in the form of a 3rd pin. However, with the increase in more and more powerful devices, suffering from electric shock became a higher risk. Originally, all electrical devices were fitted with 2-pole plugs, which means that the devices were not earthed and that all mains sockets were constructed for 2-pole plugs. ![]() Company Profile (Name, Tel, Fax, Address, and Webpage)ĥ.2-pole means that the device plug is not earthed and it normally has two pins that transmit electricity. ![]() Usually the sample orders take about 2~3 business days, and the mass orders take about 7~14 business days after the order is placed.Ī: Please provide us some information as below:ģ. Q: How long is the Lead Time after placing an order?Ī: The Lead Time depends on a number of factors, such as the stock and production status. Sea Shipping and Air Shipping: It will be depended on thr Logistuc Schedule after remitting the Payment. Exxpress Service: The ETA will be 3~7 days after remitting the Payment. In addition, you can choose a way you prefer to install your terminal blocks (by screwing, plugging, welding or you can clip or screw them on a DIN rail)? Or do you have any other special requirement (heat resistant, grounding, different colors or other customized demand)?Ī: We send our goods from Taiwan, and the delivery time depends on the location of delivery address, and the shipping way will be Express Service, Sea Shipping, or Air Shipping for your reference. Q: Which type of Terminal Block should I choose?Ī: First, you need to check how much ampere and voltage rating you require and how many wires need to be connected, and how to be connected. Let us know on your requirement we will try to save your budget and meet deadline. For regular mass production, shipments can be arranged by air-shipping, sea-shipping or express. For small quantity, shipment is prefered to shipping with express by UPS, DHL, EMS, TNT or FedEx to meet your deadline on time worldwide basis.Ģ. ![]() Description TGP-085-03A 600V 85A 3 Pole Power Terminal Block ![]()
