Anderson SB connectors have become a standard for reliable high amperage connections.

Anderson Power Products (APP) is an industry leader in the design and manufacture of high power interconnects and accessories. Founded in 1877, APP manufactured products to support the Mining and Railway Industries. Today, as a result of innovative design and development, APP has evolved into a valued supplier for a wide variety of markets including Back-up Power, Telecom/Datacom, and the Material Handling Industries.

Anderson SB Connectors are available in several sizes - 50 amp, 175 amp, and 350 amp are the most popular. Several colors are available, but we normally only stock red, black, green - but check our webstore listing, it changes quite often. Each color will mate only with another connector of the same color and size. All are suitable for AC or DC SBup to 600 volts. There is a 120 amp version, but we do not stock it as the price is higher than the 175.
This hermaphroditic (there is no male or female, each side is identical) connector was invented by Anderson Power Products.

Individually replaceable contacts enable easy field service. Spring loaded silver plated, contoured contacts have a self-wiping cleaning action, which ensures greater conductivity and longer life.

Generally, the 30 and 50 amp are used for small to medium PV array connections (or sub arrays of large systems) and small power and battery connections. The 175 and 350 amp units are used for larger batteries and large arrays. They may also be used for inverter connections. Rated for AC and DC, up to 600 volts.
 Anderson connectors are used extensively in modular systems, especially in commercial and industrial applications. The 50 amp units are often used for solar panel array and subarray connections for ease of testing, assembly, and maintenance. The 175 and 350 amp connectors are often used in battery and/or inverter connection systems. We use these on most of our larger systems, and nearly all industrial and commercial systems.
Anderson 350 amp SB connectors. All sizes are similar. Two connectors are required for a set. Since several colors are available, circuits may be color coded to suit your needs. It is common to use yellow for 12 volts, red for 24 volts, and blue for 48 volts. Contacts must be soldered or crimped (since a special crimper is required for best connection, we recommend soldering if you are going to do it yourself).

The product of Elinker Electric can replace the Anderson connector,As a connector manufacturer with global strategic planning, Elinker Electric is based in Germany, from Europe to Asia, the Americas, gathering resources used in our global high-quality products and services. We have cooperations with GE, Frisetta, LEIPOLD and other high-quality raw material suppliers to ensure that our raw materials are the first-class. We provide a range of fixed, removable PCB terminal blocks and other wiring products to meet the most needs. To the difficult and special wiring requirements, we would like to offer technical advice and implement the design.
