KUP Series: This indicates that the relay belongs to the KUP family of relays, known for being versatile, general-purpose relays used in various applications. These relays are typically designed for panel mounting and feature quick-connect terminals for easy installation.
14D55: This part of the model number specifies certain characteristics of the relay:
14: Refers to the contact arrangement, which is 3PDT (3 Pole Double Throw), also known as 3 Form C. This means the relay has three sets of contacts, each capable of switching between two positions (normally open and normally closed).
D: Indicates that the relay has a DC (direct current) coil, meaning it is actuated by a DC voltage.
55: This likely denotes a specific variant or feature within the KUP series, such as the type of enclosure, mounting style (bracket mount), or terminal configuration (quick-connect terminals, typically 4.75mm or 0.187-inch). It distinguishes this model from other KUP relays with different features.
80: Based on the naming convention observed in similar models (e.g., KUP-14D55-12, KUP-14D55-24, KUP-14D55-48), the number at the end represents the coil voltage in volts DC (VDC). Therefore, "80" suggests that this relay has a coil rated at 80VDC, meaning it requires an 80-volt DC input to activate the coil and switch the contacts.
