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.

In our offer, we have many types of thermal relays from leading manufacturers. Our products, due to the manufacturers, are characterized by high quality and long durability. Thermal relays are used in many branches of industry. The parameters of our devices correspond to those in the manufacturers' datasheets, which translates into operational safety of the installations in which they are installed.

What is a thermal relay?

Thermal relays are used to protect electric motors, transformer windings, or power electronic components. During operation, a motor may be overloaded due to excessive mechanical load, e.g., cutting wet wood or a drop in supply voltage. Prolonged increase in current consumption can damage the motor due to overheating. A thermal relay is a device that protects the motor from overheating effects.

How is a thermal relay constructed?

A thermal relay uses PTC or RTD (Pt100) sensors. When the nominal temperature, which could threaten the device, is exceeded on the sensor, the relay detects this change and triggers an alarm and often disconnects the protected circuit.
