KRPA Series Panel Plug-in Relay

Category: Electronics, Relays, TE Connectivity

General Overview

The KRPA Series Panel Plug-in Relay, manufactured by Potter & Brumfield, is designed for general purpose applications. It offers a variety of contact arrangements, including 1, 2, and 3 form C (CO) configurations, and is capable of handling currents ranging from 5 to 10A. It is equipped with octal type termination, facilitating efficient and swift installation processes. Select models include an indicator lamp, providing a visual cue of the relay’s operational status.

Typical Applications

These relays are particularly suited for use in baggage handling systems, lighting controls, inspection equipment, and marine applications.

Approvals and Technical Data

The KRPA Series is certified by safety standards including UL E22575 and CSA LR15734. Detailed technical data is made available upon request, ensuring compliance with industry regulations.

Coil Specifications

The relays come in various AC coil versions, featuring operating voltages from 5.1 VAC to 204.0 VAC and rated coil powers around 2.02 VA. The coil resistance parameters are provided for users interested in the electrical characteristics of the relay.

Contact Data

Contact arrangements for the relays vary, with options of 1, 2, or 3 form C (CO). They are rated for use with 240VAC and can handle up to 10A of current. The contacts are made from silver cadmium oxide (AgCdO), ensuring durability and reliability. The minimum recommended contact load is 300mA at 24VDC, with operation frequencies pegged at 60 operations per hour for single contacts, and 360 operations per hour for multiple contacts.

Contact Ratings

The relays are rated according to UL 508 standards, with several models varying in performance metrics such as allowable current and horsepower at different voltages (120VAC and 240VAC).

Mechanical Endurance and Insulation Data

The mechanical endurance is rated at 10 million operations for KRPA, and insulation data is provided to demonstrate the dielectric strength and resistance between contacts, coils, and adjacent contacts.

Materials Compliance and Environmental Considerations

Compliance with EU RoHS, China RoHS, REACH, and Halogen content standards is maintained. Ambient temperature tolerances for KRPA series in DC and AC coils are noted, with temperature ranges given for each type. Environmental protection categories are mentioned, along with information about terminal types and relay weights.

Additional Components

Accessories compatible with the KRPA Series, such as various types of sockets and track mounts, are briefly listed with product codes to guide procurement and installation processes.
