Allen-Bradley 700-N400A1 AC Relay

Allen-Bradley 700-N400A1 Bulletin 700 AC Relay is a four-pole, four normally open industrial control relay from the Type N family (Series C) designed for panel mounting in control systems. It consolidates four independent NO contacts in a single base to streamline multi‑circuit switching from one device, ideal for interlock logic and sequencing in automation panels. The coil accepts 110 VAC at 50 Hz or 120 VAC at 60 Hz (Series C), aligning with common regional mains supplies, and is specified for 50/60 Hz operation. The contact rating is 10 A, making it suitable for light-to-medium industrial loads in panel-mounted control schemes. As a Bulletin 700 device, it is part of Allen-Bradley’s legacy 700‑N relay family, widely used in machine control and process automation where a compact, multi-pole relay is required.
