Products that are marked "On Order" in the "Available Quantity" column are usually not in stock. Such products are available for purchase, however, due to their limited customer base, they usually have higher minimum quantities. DACPOL offers products that are not in stock for the following reasons: DACPOL currently has a large number of electronic components in stock and adds new products every day, however, tens of thousands of additional components and their various variants are available from our suppliers. Even though it is unreasonable to have all these products in stock due to the limited sales, we believe that it is in the best interest of our customers to make them available. Our goal is to inform customers about the maximum number of products available and enable them to make decisions based on specifications, prices, availability, required minimums and our technical advice. Please note that selecting the "In Stock" checkbox may limit the display to only products available for delivery straight from the shelf.

Our offer includes various types of thermal relays from leading suppliers. We provide high-quality products with long work durability. Overload relays can be used in many industrial sectors. The parameters correspond with catalogs from their producers, which guarantees the safety of installations.

What is a thermal relay?

Thermal relays are used for protecting power-electric engines, winding of transformers, or power-electronic components. During work, the engine can be overloaded because of mechanical overload e.g. cutting wet wood or power overload. A long increase in intake power can damage the engine because of overheating. In case of the disappearance of phase current or given value the device disconnects the control system. A thermal relay is a device protecting the engine from overload effects.

Construction of a thermal relay

A thermal bimetal relay is made from bimetals, which are heated with the current intaken by the engine and system of the splay joint. This joint starts working through the bending of bimetals because of the temperature increase. The bimetals have to be inserted into the main system of the engine while the joint into the control system of the relay.
