The ABB 23AE 21 Inverter is a high-efficiency industrial control module designed for precise motor speed control in demanding environments. It ensures reliable operation and energy savings across various industrial applications.

The CM‑SRS.21S is a single‑phase current‑monitoring relay from ABB’s CM‑SRS series. It monitors AC and/or DC current and triggers an output when the measured current goes above or below a set threshold — providing either over‑current or under‑current protection. The device supports multiple measuring ranges for flexibility, and allows adjustment of hysteresis and tripping delay. Output is provided via dual changeover (SPDT) contacts, and the relay is designed for DIN‑rail mounting with standard screw‑type terminals.

The Schneider Electric WATSN160B/4A Automatic Transfer Switch (ATS) is a four‑pole changeover device used in low‑voltage AC power systems to ensure continuity of electrical supply. It performs automatic and manual switching between two independent power sources, such as a utility mains and a standby generator, to maintain uninterrupted power to connected loads during supply disturbances.
