In electronic components, the "Series" refers to a group of products that share similar characteristics, designs, or functionalities, often produced by the same manufacturer. These components within a series typically have common specifications but may vary in terms of voltage, power, or packaging to meet different application needs. The series name helps identify and differentiate between various product lines within a manufacturer's catalog.

The current rating of a contact is defined as the current level that creates a certain temperature rise of the contact spring — usually 20°C or 30°C. Both electrical and thermal factors govern the heat created by the current.

Coil voltage refers to the electrical potential difference that is applied across the coil of an electromechanical device, such as a relay or a solenoid. This voltage is essential for energizing the coil, creating a magnetic field that enables the device to perform its intended function, such as opening or closing contacts. The coil voltage is specified by the manufacturer and varies depending on the design and application of the component, commonly available in standard values like 5V, 12V, 24V, and others. Proper selection of coil voltage is crucial for optimal performance and longevity of the device.
