The ABB PR122/P‑LSIG 1250 A is a low‑voltage air circuit breaker (ACB) from ABB’s Emax series, designed for use in industrial and commercial electrical distribution systems. It is rated for a continuous current of 1250 A and features the PR122/P‑LSIG electronic protection trip unit, which offers adjustable long‑time (overload), short‑time, instantaneous, and earth‑fault protection.

The ABB 2CDS274001R0164 is a 4‑pole miniature circuit breaker (MCB) from ABB’s System Pro M Compact S200M series. It is designed to provide overload and short‑circuit protection for electrical circuits in residential, commercial, and light industrial installations. The breaker uses a thermal‑magnetic trip mechanism to protect wiring and connected equipment by automatically disconnecting the circuit when an overcurrent or short‑circuit condition occurs.

The ABB 5S4000 R4000 AR1/LI WMP 3P NST is a low‑voltage air circuit breaker (ACB) designed for heavy‑duty electrical distribution and protection in industrial and commercial power systems. It belongs to ABB’s 5S series, supporting a continuous rated current of 4000 A in a three‑pole (3P) configuration. The breaker is built with a withdrawable moving part (WMP) format, enabling easy insertion and removal from compatible switchgear frames for maintenance and operation.

The ABB E1N1250R1250 PR122/P‑LSIG is a low‑voltage air circuit breaker (ACB) from ABB’s SACE Emax E1N series, rated for a continuous current of 1250 A. It features the PR122/P‑LSIG electronic trip unit, offering adjustable protection functions including long‑time (overload), short‑time, instantaneous, and earth‑fault releases.

The ABB PR121/P 1250 A is a low‑voltage air circuit breaker equipped with a PR121/P electronic protection trip unit. It is designed for use in industrial and commercial electrical distribution systems to provide reliable protection against overloads, short circuits, and earth faults in three‑phase networks with a continuous rated current of 1250 A.

The ABB E2.2N 2500 A 3‑pole air circuit breaker is a low‑voltage power circuit breaker designed for industrial, commercial, and utility electrical distribution systems. It provides high‑capacity protection and switching for three‑phase power networks with a rated current of 2500 A and is suitable for installation in main distribution panels, switchgear, and motor control centers.

The ABB F5S 4000 A is a low‑voltage air circuit breaker (ACB) from ABB’s legacy SACE Megamax F5S series. It is designed for heavy‑duty electrical distribution and industrial protection applications where high continuous currents and reliable fault interruption are required. This model is configured as a three‑pole (3P) device with a fixed mounting format (denoted by the “F” in the designation), intended to be permanently installed directly onto busbars in switchboards, distribution panels, or motor control centers.

The ABB E2.2N 2500 A is a low‑voltage air circuit breaker (ACB) from ABB’s SACE Emax 2 E2.2N series, designed for electrical distribution and protection in industrial and commercial power systems. It is built to handle continuous currents up to 2500 A in three‑phase networks and protects against overloads, short circuits, and fault conditions.
