Power Relays, Over 2 Amps

The 85102955 is an industrial 3-pole relay with a very high insulation voltage rating and silver-based contacts. It can operate in temperatures between -10° and +70°C and is suitable for use with inductive loads up to 120 % of rated current. A plus point of this relay is its long working life of 10 million operations. Given the high voltage rating of this relay, it can be used in applications requiring high-voltage insulation.

The 85102955 has a rating of 2 Amps at a voltage rating of 5A and an insulation resistance of 500 Mohm. The other technical specs include a DIN rail mounting option, a current of 30mA and a switched voltage of 7.2V. Furthermore, the relay terminals can be soldered for better stability and durability. The relay can be used on systems which need current up to 2 A and high current spikes.

The working principle of 85102955 is based on a bi-metallic strip (most commonly made of copper and aluminium) which is heated up with electric current to a specific degree, before making or breaking an electrical circuit. When the current doesn\'t flow, the bi-metallic strip quickly cools down and the contacts separate, releasing the switch and breaking the electrical circuit. When the electric current is applied, the bi-metallic strip heats up to a certain point and makes the contact between two terminals, completing the electrical circuit. The bi-metallic strip cools down again and the contacts separate.

The 85102955 is primarily used in industrial applications where high voltages are involved, like in industrial electrical panels, high powered motors, power transformers, power lines, motor starters and high-voltage surge protection systems. The long operating life and very high insulation resistance of this relay makes it suitable for demanding applications that require safety and reliability. The robust construction and reliable performance of the 85102955 relay means it will offer reliable operation in a variety of environments. Due to its stable design, the 85102955 will provide years of faithful service without maintenance.
