Power Relays, Over 2 Amps

The 2981125 Power Relay is an Over 2 Amps model from the Kraus & Naimer company. This relay is designed for applications in the power industry, where high currents and designs with safety considerations can become a challenge. This device is also suitable for use in harsh environments, with a robust casing and high temperature and dielectric strength.

Relay Design

The device is rated to switch currents up to 2 Amps, while its contact gap voltage rating is 800Vac/dc in both make and break. Unlike some other relays, this model has two form-C contacts, allowing for a range of switching patterns. The contacts are rated to make 4A, break 1A and are rated for operation in both dependant and independent operation modes. The contacts are also protected from arcing and welding through the use of silver-platinum alloy contacts.

Installation and Control

The 2981125 can be either mounted using screws and brackets on a panel or using mounting slots. The unit is also equipped with a cable carrying arm which makes it easy to install. The unit is normally supplied with a 12VAC/DC coil, but can also be supplied with higher or lower voltage coils.

The 2981125 is designed to be operated with an electromagnet. When energized, the electromagnet drives the set of armatures and, in turn, the contacts that then open and close. The relay can also be controlled through an option log which allows the user to switch between Normally Open or Normally Closed contact configurations. The relay also has a test/reset switch that will release the contacts from the electromagnet and reset the relay after power has been lost.

Should You Buy The 2981125?

The 2981125 is an excellent choice for applications in the power industry, where high currents and safety considerations are key. Its robust construction also makes it suitable for harsh environments and its cable carrying arm makes it easy to install.

If you\'re looking for a high-power relay that provides reliable performance and is suitable for industries such as power generation, then the 2981125 is an ideal choice.
