ABB IEC/EN 60947 contactor

Product Overview

The IEC/EN 60947 standard is the core international specification for low-voltage switchgear and control equipment, covering various aspects such as equipment rating, structural requirements, performance testing, safety standards, etc. ABB IEC/EN 60947 contactors are designed and manufactured strictly in accordance with this standard, from raw material screening to production process control, to finished product testing. Every step is rigorously controlled to ensure that the product can operate stably under complex working conditions, providing users with safe and reliable control solutions.

This series of contactors is mainly used in circuits with AC 50Hz or 60Hz, rated voltage up to 1000V, and rated current up to 2500A. Through the on-off control of electromagnetic coils, the contact action is controlled to achieve start stop control of loads such as motors, heaters, lighting equipment, etc. It is widely used in various low-voltage distribution systems and industrial automation production lines.

Core advantages

1. Excellent electrical performance, stable and reliable

The ABB IEC/EN 60947 contactor adopts an optimized contact design, using high conductivity and wear-resistant silver alloy materials, greatly improving the electrical and mechanical life of the contacts. Its rated connection and disconnection capabilities far exceed the standard requirements, and it can effectively cope with the impact current during load start-up, avoiding faults such as contact welding. At the same time, the contactor is equipped with an efficient arc extinguishing system and adopts a grid type arc extinguishing structure, which can quickly extinguish the arc generated when disconnecting the circuit, reduce the damage of the arc to the equipment, and improve the safety of circuit operation.

2. Efficient and energy-saving, reducing operating costs

In the current era of increasing energy scarcity, energy conservation has become an important consideration for industrial equipment. The ABB IEC/EN 60947 contactor adopts a low-power coil design, which significantly reduces the active power loss of the coil by optimizing the electromagnetic system structure. Compared with traditional contactors, its coil power consumption can be reduced by more than 30%, and long-term operation can save users a lot of electricity costs. In addition, the efficient heat dissipation structure design of the contactor reduces the heat generation during equipment operation, further improving energy utilization efficiency.

3. Wide voltage adaptability range and strong environmental adaptability

Voltage fluctuations in industrial sites are a common problem that affects the stable operation of contactors. The coil of ABB IEC/EN 60947 contactor supports a wide voltage input range and can usually operate stably between 85% and 110% of the rated voltage, adapting to voltage fluctuations in different regions and working conditions. At the same time, the product has good temperature resistance, moisture resistance, and vibration resistance. The working environment temperature range can cover -25 ℃~+70 ℃. Even in harsh environments with high temperature, humidity, and high dust, it can maintain a stable working state and is suitable for complex industrial scenarios such as metallurgy, chemical engineering, and mining.

4. Modular design, easy installation and maintenance

To improve installation and maintenance efficiency, ABB IEC/EN 60947 contactors adopt a modular structure design. The main body, auxiliary contacts, coils and other components of the contactor can be flexibly combined, and users can choose different configuration schemes according to their actual needs, reducing the difficulty of equipment selection. In addition, the product adopts standardized installation dimensions and is compatible with mainstream installation rails, making the installation process simple and fast. In terms of maintenance, the contact points, coils, and other vulnerable components of the contactor are easy to replace, reducing equipment downtime and improving production efficiency.

5. Comprehensive security protection to ensure the safety of personnel and equipment

Safety is the primary principle of power control. The ABB IEC/EN 60947 contactor is equipped with various safety protection functions, including overload protection, short circuit protection, undervoltage protection, etc., which can effectively avoid equipment damage and safety accidents caused by circuit faults. The outer shell of the product is made of high-strength insulation material, which has good insulation performance and anti electric shock protection, meets international safety standards, and provides comprehensive safety protection for operators and equipment.
