Allen-Bradley 810-A16C Inverse Time Relay

Allen-Bradley 810-A16C Inverse Time Relay is a Bulletin 810 series inverse-time current relay from Rockwell Automation, engineered to provide overcurrent protection with a time delay that decreases as current increases. The 810-A16C model specifies a coil current rating of 100 A, identifying the nominal current it is designed to sense in protection schemes. Used in motor and feeder protection, this relay responds to overcurrent by energizing its outputs in a time-versus-current fashion, aligning with the standard inverse-time current characteristics documented for Bulletin 810 relays. This model is part of Allen-Bradley’s legacy line of time-delay current relays and is described in Rockwell's 810-series literature.
