The ABB EF205-210 is a residual current operated relay or residual current monitoring unit. It is a core component of a modular earth leakage protection system and belongs to the EF200 series. This device does not directly break the circuit itself; instead, it is designed to be used in conjunction with a separate circuit breaker (MCB/MCCB) and a shunt trip coil.

The ABB MP3-30R is a 30 A rated Masterpact (MP) series three-pole (3P) rotary main switch or load break switch. It serves as a reliable, manual main circuit disconnect switch designed for service isolation, maintenance safety, and functional switching in low-voltage distribution systems.

The ABB S2C-H6R is a 100 A, 3-pole, High Magnetic (H-type) Moulded Case Circuit Breaker (MCCB) from ABB's Form 2a (S2C series), also known as the Tmax series in certain markets. This specific model is engineered for applications requiring a high withstand and interrupting capacity for severe fault conditions.

The ABB CR-M4SS is a mushroom-head emergency stop push button from ABB's renowned CR-M series of rugged industrial control devices. It is a critical safety component designed to provide a highly visible, immediate, and reliable means of stopping machinery or processes in hazardous situations, in compliance with safety standards.

The ABB MS116-0.63 is a single-pole (1P), miniature circuit breaker (MCB) from ABB's MS116 series. This specific model has a very low rated current of 0.63 Amperes (630 mA). It is designed for the protection of sensitive control circuits, instrumentation loops, signal circuits, or small auxiliary devices where very low operating currents are present. Its primary function is to provide reliable protection against overloads and short-circuits in these delicate applications, preventing damage to expensive equipment like PLC modules, transmitters, relays, or low-power power supplies.

The ABB AS12-30-01-20 is a **modular ** indication light unit, specifically a push-to-test signal lamp (indicator) with a monochrome (single-color) lens. It is a component from ABB's System Pro M compact® S200 series accessory line, designed for mounting on standard DIN rail in control panels, switchboards, and industrial enclosures.

The ABB AX18-30-10 is a hand-held industrial manual motor starter and protector, commonly known as a manual motor starter (MMS) or manual motor protector (MMP). It is a compact, self-contained device that combines the functions of a disconnect switch, a thermal overload relay, and a magnetic short-circuit protector into a single unit.

The ABB CT-APS.12S is a compact, high-precision split-core current transformer (CT) designed for easy installation in electrical measurement and energy monitoring systems. Its primary application is for non-invasive current sensing on existing busbars, cables, or conductors without the need to disconnect the circuit.

The ABB E218-16-11 is a 16 A, 2-pole (2P), C-curve Earth Leakage Circuit Breaker (ELCB), more precisely known as a Residual Current Circuit Breaker with Overcurrent Protection (RCBO). It belongs to the widely used ABB Domae or E200 series (depending on market), which is designed for residential and commercial electrical installations.

The ABB S201-B6 is a 1-pole (single-pole), B-characteristic Miniature Circuit Breaker (MCB) from the ABB System Pro M compact® S200 series. This is a fundamental component for overcurrent and short-circuit protection in residential, commercial, and light industrial electrical installations.
