ABB A75N3-30 Motor Starter With Overload Relay

ABB A75N3-30 Motor Starter With Overload Relay is a size-3 combination starter for three-phase motor control that pairs a contactor with an integrated overload relay to protect and start motors in industrial control panels. It uses a 120 V coil, making it suitable for standard control circuits and enabling reliable switching of mid-sized motors in a variety of industrial settings, while the combination design reduces panel wiring and saves space. The overload relay provides automatic protection against overload conditions by interrupting current when preset limits are exceeded, helping safeguard motor windings and electrical circuits. This size-3 unit is intended for use in 3-phase motor circuits where a compact form factor and integrated protection are desired, and it can be wired into common control schemes for straightforward start/stop operation. In practice, the A75N3-30 offers a single, cohesive motor-control solution that combines switching and protection in one durable package, simplifying installation, servicing, and future modifications.
