TE Connectivity KRP-5AG-120 Relay

TE Connectivity’s Potter & Brumfield KRPA-5AG-120 general purpose power relay (also cataloged as KRP-5AG-120) is an AC coil, monostable SPDT-CO relay that switches up to 240 VAC with a 10 A contact rating. It uses a 120 VAC coil and draws 17.5 mA, requiring about 2.1 VA of coil power, with a coil resistance of 2.25 kΩ. The relay contacts are AgCdO and configured as 1 Form C (SPDT-CO), enabling common, normally open, and normally closed paths for AC loads. The relay is socketable for plug-in installation, using an 8-pin octal footprint, and TE provides accompanying CAD data and socketing options. Its external dimensions are approximately 35.70 mm long, 50.80 mm tall, and 35.70 mm wide, with a weight around 85 g. The KRPA-5AG-120 is designed for general‑purpose switching in industrial panels, automation, HVAC controls, and equipment where reliable 10 A switching at 120 VAC coil is required. TE emphasizes a monostable coil for predictable operation, and the KRPA family is widely used in control circuits needing robust, compact relays with a plug‑in socket option. As with any replacement, verify exact form factor and coil rating to ensure compatibility with your socket and mounting hardware.
