The ABB E4N3200 D LSIG 3‑pole WHR Air Circuit Breaker is a high‑current low‑voltage protective device from ABB’s SACE Emax E4N series designed for industrial and commercial three‑phase power distribution systems. It uses an electronic LSIG overcurrent trip unit to provide coordinated protection against long‑time overloads (L), short‑time faults (S), instantaneous short circuits (I), and ground faults (G). The breaker is configured with withdrawable (WHR) style connections, allowing the unit to be safely removed from its switchgear frame for maintenance or service without disconnecting the busbars. This breaker is well‑suited for use as a main distribution or feeder breaker in electrical switchgear, feeder panels, and power distribution systems requiring reliable high‑current protection.

The ABB AIN200 Analog Input Module is a high-precision sensor interface designed for industrial automation systems, enabling accurate data acquisition and control.

The ABB 1SDA051041R1 is a three‑pole molded case circuit breaker from ABB’s SACE Tmax T2H range with front fixed terminals and a thermal‑magnetic trip unit. It is designed to protect low‑voltage electrical distribution circuits from overload and short‑circuit faults while providing reliable switching in industrial and commercial applications. The breaker features adjustable trip settings and robust construction to ensure dependable performance in power distribution systems.
