Blade type power connectors are a popular and cost effective form of power connection. This article aims to provide information on the 556881-8 blade type power connector, the application field and the working principle.

Overview

The 556881-8 is a compact, robust, and waterproof motorized connector offering a great contact force and a reliable connection. It has an integrated pin-lock design and a wide range of removable contacts and cables, making it suitable for many applications.

The 556881-8 is available in several sizes, including two pole (1/2"), three pole (3/4" and 7/8") and four pole (1" and 1-1/2") versions. The connector has been designed for power connections in industrial and commercial environments. It is suitable for most applications where reliable and secure connection is required and it is especially useful for motors and large equipment.

The 556881-8 has been designed to meet a wide range of safety and performance requirements, such as UL and CSA certifications. It is also rated for a maximum current of 120 A per contact.

Application Field

The 556881-8 is suitable for use in a variety of industrial and commercial applications. It is particularly useful for motor installations, where reliable power connections must be maintained at all times. It can also be used in many large equipment applications.

Possible applications for the 556881-8 include industrial machinery, HVAC systems, factory automation, outdoor lighting systems, and power supply applications. It is particularly suitable for applications with long run times or high current ratings, as it is able to withstand high temperatures and long duty cycles.

Working Principle

The 556881-8 blade type power connector works by creating an electrical connection between the contacts, which is then maintained by a pin-locking mechanism. When the connector is inserted into a receptacle, the pin-locking mechanism engages and creates a secure connection. This provides a reliable power connection, even at high temperatures and long run times.

The pin-locking mechanism also provides protection against accidental disconnection or misalignment. The 556881-8 is designed so that it will not disengage, even with the application of a large force. This makes it suitable for use in high vibration environments.

The 556881-8 also has a built-in thermal protection system. The system monitors the temperature of the contacts and will disconnect if it exceeds the specified limit. This ensures that the connector operates within safe temperature limits and prevents damage to the equipment or the connection.

Conclusion

The 556881-8 blade type power connector is a robust, waterproof, and reliable connector suitable for many industrial and commercial applications. It has a secure pin-locking mechanism, a wide range of contacts and cables, and is rated for a high current of 120 A per contact. The built-in thermal protection system ensures that it operates within safe temperature limits and is suitable for use in high vibration environments.
