The ABB AUX-C 1Q1SY-Cabled 250vac/dc T4-6 is a factory-wired, modular auxiliary contact block designed specifically for attachment to ABB's Emax 2 (E2) series of air circuit breakers (ACBs) and molded case circuit breakers (MCCBs). Its article number is 1SDA054910R1.

The ABB CEPY1-2001 is a digital input (DI) module from the Freelance distributed control system (DCS) product family. It is a critical component in industrial automation, designed to interface field-mounted digital sensors and switches with the ABB Freelance control system.

The ABB M3SS4-10B is a miniature control and signal switch from the M3S series, which is part of ABB's System M line of modular control and indication devices. It is designed for low-current switching applications in control panels, machinery, and automation systems.

The ABB CM-MSS.21S is a surge protection device (SPD), also known as a Type 2 / Class II surge arrester, from ABB's CM-MSS modular surge protection system. It is a critical component in safeguarding electrical installations and sensitive equipment against damaging transient overvoltages caused by indirect or remote lightning strikes and switching operations within the power network.

The ABB XT2N160 TMA 100/1000 FF 3P is a high-performance, current-limiting, molded-case circuit breaker (MCCB) from ABB's advanced XT series. It is designed for main circuit protection and distribution in commercial buildings, industrial plants, and infrastructure applications where high breaking capacity and precise protection are required.

The ABB TINA 11A is a discrete, monostable electromechanical latching relay from ABB's highly versatile TINA (Terra Indicating and Auxiliary) relay series. This relay is a critical component in control and automation systems, designed to provide remote switching, signal amplification, and interlocking functions.

The ABB S203M-C20 is a three-pole miniature circuit breaker (MCB) from the enhanced-performance S200M series (Moulded Case), part of the System Pro M compact S200 line. It represents a robust and reliable solution for protecting three-phase electrical circuits. This device features a rated current of 20 Amperes per pole and the widely used "C" type tripping characteristic. The defining feature of the S200M series is its superior 10 kA breaking capacity, providing a higher safety margin in installations with potentially higher fault currents compared to the standard 6 kA S200 series.

The ABB MS116-10 is a compact, space-saving miniature circuit breaker (MCB) from the MSxxx series within the broader System M (M200 S-series) family. It features a unique single-pole plus neutral (1P+N) configuration.

The ABB NS44E-25 is a 25-ampere, 4-pole miniature circuit breaker (MCB) from the System E (S200 S-series) product line.This device is a compact MCB designed to provide simultaneous overload and short-circuit protection for all four conductors of a three-phase circuit (three phases and the neutral). It acts as an automatic switch that trips (disconnects) all poles when a fault is detected on any single pole, ensuring complete isolation of the load.

The ABB MJS2-60B is a high-quality rotary isolator switch, also commonly known as a disconnector or load break switch, from ABB's MJ/MJS series of manual control and switching devices. It serves as a main switch or functional isolator in electrical distribution boards and industrial enclosures.
