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.

The ABB MCBH5-00 is a compact, plug-in auxiliary contact block designed for attachment to ABB System Pro M compact® S200 and S280 series miniature circuit breakers (MCBs) and residual current circuit breakers (RCCBs). It serves as a remote, electrically isolated signaling device, providing a reliable indication of the main breaker’s status (ON/OFF or TRIPPED).

The ABB AF09Z-40-10-21 is a 1-pole (single-module) miniature circuit breaker (MCB) from the System Pro M compact® AF series. It features a Z-characteristic (selective) tripping curve, specifically designed for the protection of highly sensitive circuits such as those containing semiconductors, transformers, or measurement loops. The "Z" curve provides a very fast response to both short-circuit and low-level overload faults, making it ideal for applications where even minor overcurrents must be quickly interrupted to prevent damage to delicate equipment.

The ABB MPMT3‑11R is a modular pushbutton operator designed for industrial control panels and automation systems. It features a red mushroom head pushbutton with maintained action (latching) and a compact design that fits standard 22 mm panel cut‑outs. The operator itself does not include contact blocks, allowing you to choose and install the appropriate electrical switching modules for your specific control function. It is typically used as an emergency or stop control in machinery, panel, or human‑machine interface applications.

The ABB OHBS2PJ is a snap‑on selector handle accessory designed for use with ABB door‑mounted disconnect switches and load disconnect devices. It provides a manual ON/OFF selector interface that attaches directly to the switch mechanism without the need for a separate extension shaft. The handle enhances safety, usability, and compliance in electrical control and distribution panels.
