TE Connectivity Time Delay Relay, Dpdt, 10S, 277Vac; Contact Voltage Vdc Potter&brumfield Te Connectivity CKB-38-77010

The CKB-38-77010 is a delay on dropout time delay relay with a DPDT relay contact, rated for 10A at 277VAC or 30VDC resistive load, and operates on 120VAC with a timing range of 0.1 to 10 seconds. It features a knob-adjustable timing control, an 8-pin octal plug termination, and a white plastic enclosure. The input voltage must be applied for at least three seconds to guarantee dropout timing. It includes transient and reverse voltage protection, with a dielectric strength of 500V rms between contacts and conductors. The relay has a mechanical life of 10 million operations and an electrical life of 100,000 operations at rated load. Operating temperature ranges from -10°C to +55°C, and storage temperature ranges from -55°C to +85°C.
