Description

Used product. The ABB A205D-30 is a high-power 3-pole industrial contactor designed for switching and controlling three-phase loads in industrial applications, electrical switchboards, motors, automation systems, and power equipment.
The photographs clearly show the A205D-30 marking and a thermal current rating of Ith = 275 A, with Ie AC-1 = 275 A. The contactor has 3 main power poles, with terminals identified as 1L1–2T1, 3L2–4T2, and 5L3–6T3.
The control coil is identified by terminals A1–A2 and marked 220–230 V AC, 50 Hz. An ABB CAL18 auxiliary contact block is installed on the side, providing 1 NO + 1 NC contacts. ABB documentation identifies the CAL18 as a 2-pole auxiliary contact block with one normally open and one normally closed contact.

⚙️ Technical Specifications

• Manufacturer: ABB
• Model: A205D-30
• Type: Industrial power contactor
• Configuration: 3 main poles
• Thermal current Ith: 275 A
• Rated current Ie AC-1: 275 A
• Insulation voltage Ui: 1000 V AC
• Coil voltage: 220–230 V AC
• Coil frequency: 50 Hz
• Utilization categories: AC-1 / AC-3

• Installed auxiliary contact block: ABB CAL18
• Auxiliary configuration: 1 NO + 1 NC

The CAL18 is an ABB accessory with screw-terminal connections and IP20 protection; the CAL18-11 configuration is documented with 1 NO + 1 NC contacts.

⚡ Switching Performance

The A205D-30 nameplate indicates AC-3 ratings of:

• 220–240 V: 59 kW
• 380–400 V: 110 kW

These ratings specify the contactor's capability for controlling motor loads in the AC-3 utilization category at the indicated voltages.

The 275 A AC-1 rating applies to resistive or otherwise suitable loads under AC-1 conditions and should not automatically be interpreted as the AC-3 current rating for motor applications.

🔌 Control Coil

The coil is clearly identified by terminals:

A1 – A2

with the marking:

220–230 V AC – 50 Hz

This allows electromagnetic operation of the contactor through a 220–230 V AC, 50 Hz control circuit.

The photographs show wires connected to the coil with stripped ends. Before installation, the condition of these wires should therefore be checked and they should be properly terminated and connected according to the applicable wiring requirements.

🔧 CAL18 Auxiliary Contacts

An ABB CAL18 auxiliary contact block is installed on the side of the contactor.

The block provides:

• 1 normally open (NO) contact
• 1 normally closed (NC) contact
• Use in control, signaling, interlocking, and feedback circuits
• Screw-terminal connections

ABB documentation identifies the CAL18 as a 2-pole side-mounted auxiliary contact block with 1 NO + 1 NC configuration.

🏭 Construction and Installation

The contactor features a large industrial construction with an insulated housing, internal electromagnetic system, and three main power contacts.

The main connections are clearly identified:

1L1 – 3L2 – 5L3 → line input
2T1 – 4T2 – 6T3 → load output

The configuration is therefore designed for switching a three-phase circuit.

The contactor must be installed in a suitable switchboard or equipment compatible with its dimensions, operating currents, voltages, and environmental conditions.

🌐 Applications

The ABB A205D-30 can be used for:

• Three-phase motor starting and control
• Industrial load switching
• High-power electrical switchboards
• Industrial automation systems
• Pumps and fans
• Compressors
• Material-handling systems
• Industrial machinery
• Electromagnetically controlled power circuits
• Applications requiring auxiliary contacts for signaling or interlocking

For motor applications, always verify the actual motor current, AC-3 category, supply voltage, and coordination with upstream protection devices.

🛡️ Safety and Product Condition

The component is used and shows normal cosmetic marks and signs of previous installation visible in the photographs.

The main structure appears intact; however, as this is a high-power electromechanical device, coil functionality and contact condition cannot be certified solely from photographs.

Before recommissioning, it is advisable to verify:

• Coil resistance and insulation
• Correct operation at 220–230 V AC / 50 Hz
• Proper electromagnetic attraction and release
• Continuity of the three main contacts
• Possible contact wear or oxidation
• Operation of the CAL18 auxiliary block
• Terminal integrity
• Tightness of connections
• Any signs of overheating or electrical arcing

The coil wires visible in the photographs have stripped ends and must be properly terminated and connected before use.
