Anderson® connectors are connectors widely used in handling high currents.

Comprehensive Guide on Anderson® Connectors: Sizes, Currents, Accessories, and Applications

Introduction

Anderson® connectors are hermaphroditic connectors generally used to handle high currents in batteries and similar applications. Depending on the connector chosen, they can manage currents ranging from 20 amperes to 350 amperes. Some, like the Powerpole® series, are stackable, allowing the formation of connector blocks with a greater number of contacts, as many as desired.

Sizes of Anderson® Connectors

Anderson® connectors are available in various sizes, designed to meet different needs and applications. The most common sizes include:

SB50 Connectors: Support up to 50 amperes (60 mm²), ideal for low-power applications.
SB120 Connectors: With a capacity of up to 120 amperes (16-25 mm²), perfect for medium-power applications.
SB175 Connectors: Support currents up to 175 amperes (50 mm²), used in high-power applications.
SB350 Connectors: Designed for very high-power applications, can handle up to 350 amperes (100 mm²).
Powerpole® Series: Available in several models: PP15/30/45: Support currents of 15, 30, and 45 amperes with cables of gauges 20-10 AWG (0.5-5.3 mm²).
PP75: Supports up to 75 amperes with cables of gauge 6-12 AWG (4-10 mm²).
PP120: Supports up to 120 amperes with cables of gauge 2-6 AWG (13.3-33.6 mm²).
PP180: Supports up to 180 amperes with cables of gauge 1/0-6 AWG (50-13.3 mm²).

Each size is available in different colors, which not only aid in visual identification but also ensure proper compatibility, as connectors of different colors cannot be interconnected.

Current Capacities

The current capacity of Anderson® connectors varies according to the connector size and the cable gauge used. Here are some typical capacities:

SB50: Up to 50 amperes with cables of gauge 6-10 AWG (4-16 mm²).
SB120: Up to 120 amperes with cables of gauge 1-4 AWG (42-21 mm²).
SB175: Up to 175 amperes with cables of gauge 1/0 AWG (53.5 mm²).
SB350: Up to 350 amperes with cables of gauge 4/0 AWG (107.2 mm²).
Powerpole® 15: Up to 15 amperes with cables of gauge 20-16 AWG (0.5-1.3 mm²).
Powerpole® 30: Up to 30 amperes with cables of gauge 16-12 AWG (1.3-3.3 mm²).
Powerpole® 45: Up to 45 amperes with cables of gauge 14-10 AWG (2-5.3 mm²).
Powerpole® 75: Up to 75 amperes with cables of gauge 6-12 AWG (4-10 mm²).
Powerpole® 120: Up to 120 amperes with cables of gauge 2-6 AWG (13.3-33.6 mm²).
Powerpole® 180: Up to 180 amperes with cables of gauge 1/0-6 AWG (50-13.3 mm²).

It is crucial to select the appropriate connector based on the maximum expected current in the application to ensure safe and efficient operation.

Available Accessories

Anderson® connectors come with a variety of accessories to enhance their functionality and adaptability:

Protection Covers: Protect the connectors from dust, moisture, and mechanical damage.
Release Handles: Facilitate the disconnection of the connectors in applications where access is limited.
Mounting Clips: Allow secure mounting of connectors on panels or surfaces.
Sealing Kits: Ensure protection against water and other environmental contaminants.

Common Applications

Anderson® connectors are used in a wide range of industries and applications, thanks to their robustness and ease of use. Some of the most common applications include:

Electric Vehicles: Used for battery connections and charging systems.
Solar Energy: Connect solar panels to charge controllers and batteries.
Industrial Equipment: Applications in machinery and high-power equipment.
Forklifts: For battery connections and electrical systems.
Backup Power Systems: Used in UPS systems and battery banks.

Recommended Colors and Voltages

Anderson® connectors are available in different colors and can be connected between two connectors of the same type even if they are of different colors. However, it is recommended to use certain colors according to the nominal voltage of the application to avoid confusion and ensure correct identification:

Yellow: 12V
Orange: 18V
Red: 24V
Gray: 36V
Blue: 48V
Green: 72V
Black: 80V
Brown: 96V
Violet: 120V
White: 144V

Conclusion

Anderson® connectors offer a reliable and versatile solution for various electrical and electronic applications. Understanding the different sizes, current capacities, and available accessories is crucial to selecting the appropriate connector for each specific need. Their wide range of applications demonstrates their importance in the modern industry, ensuring safe and efficient connections in all types of systems.
