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.
