Description

Used product. The ABB AL16-30-10 is a power contactor from the ABB AL series, designed for switching and controlling three-phase electrical loads and motors in industrial applications.

The contactor features 3 main poles, clearly identified as 1L1–2T1, 3L2–4T2, and 5L3–6T3, together with an integrated 1NO auxiliary contact, identified by terminals 13NO–14NO.

The contactor belongs to the ABB AL series with a DC coil. The AL16-30-10 designation identifies the version with 1 normally open auxiliary contact. However, the complete coil voltage marking is not legible in the photographs. Since this series was available with different coil voltages, the exact coil voltage must be verified directly on the component before connection.

The component shows normal signs of previous use, including light abrasions and superficial marks on the plastic parts and terminals. Electrical operation cannot be certified from photographs alone; a test of the coil, main contacts, and auxiliary contact is recommended before installation.

ABB specifies an AC-1 rating of 30 A for the AL16-30-10 and an AC-3 current rating of 17 A at 415 V, corresponding to 7.5 kW.

AC-3 Rated Power

According to the values indicated for the unit:

• 230 V: 4 kW
• 400 V: 7.5 kW
• 500 V: 9 kW
• 690 V: 9 kW

The AC-3 current rating varies according to voltage and operating conditions. For motor applications, the appropriate ABB rating table should therefore be used rather than relying only on the Ith value.

🔌 1NO Auxiliary Contact

The contactor features an integrated 13NO–14NO auxiliary contact, corresponding to the 1NO configuration of the AL16-30-10.

Auxiliary contact specifications:

• Configuration: 1NO
• Utilization Category: AC-15
• Rated AC-15 Current:
  • 4 A at 220/240 V
  • 3 A at 380/440 V
  • 2 A at 500 V
  • 2 A at 690 V
• Auxiliary Circuit Voltage: up to 690 V
• Terminals: Screw terminals

The auxiliary contact can be used for control, signaling, interlocking, and automation functions.

⚡ Function in the Electrical System

The ABB AL16-30-10 is used for the electrical switching of three-phase loads, allowing the load supply to be controlled through a separate control circuit.

The three main contacts switch the three phases:

• 1L1 → 2T1
• 3L2 → 4T2
• 5L3 → 6T3

The integrated 13NO–14NO auxiliary contact can be used for:

• Contactor self-holding circuits
• Status indication
• Electrical interlocking
• Control circuits
• Connection to PLCs and automation systems

The ABB AL series uses low-consumption DC coils, designed also for direct control from PLC outputs, depending on the specific coil-voltage version.

🏭 Construction & Installation

The contactor features a compact ABB construction designed for installation in electrical panels, automation cabinets, industrial machinery, and motor-control systems.

The construction includes:

• 3 main power contacts
• Integrated 1NO auxiliary contact
• Screw terminals
• Insulating body suitable for industrial applications
• Clearly identified front terminals

The AL series is classified by ABB as Block Contactors and is available with different configurations and coil voltages.

⚠️ The coil voltage must be verified directly on the component before energizing it.

🌐 Applications

Depending on the control voltage and operating conditions, the component may be used for:

• Three-phase motor control
• Industrial electrical panels
• Industrial automation
• Pumps
• Fans
• Compressors

• 3 main power poles
• 30 A AC-1
• 7.5 kW AC-3 at 400 V
• Up to 9 kW AC-3 at the indicated voltages
• Ui 1000 V AC
• Suitable for applications up to 690 V AC
• Integrated 1NO auxiliary contact
• Screw terminals
• Compact design
• Particularly interesting as a replacement for existing ABB equipment

🛡️ Safety & Product Condition

Used product, with visible cosmetic and usage marks consistent with previous installation.

Before commissioning, the following should be verified:

• Rated coil voltage, which is not legible in the photographs
• Coil resistance
• Correct mechanical operation
• Continuity of the three main contacts
• Operation of the 13NO–14NO auxiliary contact
• Condition and tightening of the terminals
• Electrical insulation

Do not energize the coil before verifying its rated voltage.

Installation must be performed by qualified personnel, with the electrical system disconnected and in accordance with the component's rated specifications.

📦 Package Contents

• 1 × ABB AL16-30-10 Power Contactor
• 1 × Integrated 1NO Auxiliary Contact

The component is supplied in the configuration shown in the photographs.

🚀 Final Description

The ABB AL16-30-10 is a compact industrial power contactor designed for switching three-phase loads, with a 30 A AC-1 rating, 17 A AC-3 at 415 V, and power up to 7.5 kW at 400 V.

The integrated 1NO auxiliary contact makes the contactor particularly versatile for control, self-holding, signaling, and automation circuits.

Important: the coil voltage must not be stated as a confirmed value based on the available photographs alone. The AL16-30-10 family was available with different DC coil voltages, so the exact voltage must be verified directly from the component before installation.
