Must be specified separately.

The ABB AF2050-30 is a heavy-duty, 3-phase (3-pole) block-type power contactor designed for high-current, high-power industrial applications. It belongs to ABB’s large-contact AF series, optimized for demanding loads such as large motors, generators, heavy distribution circuits, or industrial switchgear. The contactor is built with an electronic wide-range coil allowing operation with AC or DC control voltages (100–250 V), and includes surge-protection capabilities — making it suitable even in networks with unstable supply or voltage dips. Its robust construction supports reliable isolation, bypass, distribution, or motor-control tasks up to 1000 V.

The ABB MOD600ADOM4R is a digital output module designed for use in ABB’s RIO600 remote I/O automation system. It provides four independent digital output channels that interface field devices such as indicators, relays, valves, and actuators to a distributed control or automation system. The module forms part of a modular I/O architecture, allowing flexible expansion and configuration of remote sensing and control functions in industrial automation, power distribution, and process control applications. It is built to withstand industrial environments with robust electrical and mechanical performance.
