Allen-Bradley 700-PK200B11 AC Relay Contactor

Allen-Bradley 700-PK200B11 is a two-pole master-control AC relay (master relay) in the 700-PK family designed for direct-drive operation in industrial control panels. It provides up to a 20 A AC switching rating and is suitable for loads up to 600 V AC, making it appropriate for energizing downstream devices such as contactors and interlocks in automation circuits. The coil variants commonly include 120 V AC (60 Hz) and 110–115 V AC (50 Hz) to accommodate regional power standards. This open-type relay is designed for rail-mount installation in control cabinets, integrating with standard 700‑P family components. In Rockwell Automation’s documentation, the 700‑P master-relay devices are described as heavy‑duty relays used to drive higher-current loads in direct-drive control schemes.
