Allen-Bradley 193-BSA70B Overload Relay With Adapter

Allen-Bradley 193-BSA70B Overload Relay With Adapter is a Bulletin 193 bi-metallic overload relay that protects motors by interrupting current when the load exceeds the preset range, with a 0.4–0.6 A current rating and a manual reset for prompt recovery after an overload. The "With Adapter" version includes a mounting adaptor to pair with compatible Allen-Bradley contactors, simplifying installation in industrial control panels and enabling quick field replacement. Key specifications include a 0.4–0.6 A current range, a bi-metallic sensing element, and a manual-reset mechanism, providing intrinsic thermal protection without complex electronics. It is designed for use with compatible Allen-Bradley motor-control configurations and can be integrated into legacy and modern control schemes that rely on Bulletin 193 relays for overload protection. In practice, this relay helps safeguard small-to-moderate motors in automated systems by opening the circuit when an overload is detected, reducing wear and electrical stress on components.
