Anderson Power Products SB175 SB Series 175 Amp Connector Kit

What is a SB "Kit"?
Anderson Power Products SB connectors are available as convenient connector kits or separate individual parts.

A connector "Kit" includes all the parts needed for a single connector. A set includes (1) colored plastic housing and (2) metal contacts.

To purchase a mating connector pair, you must order a quantity of two connector kits.

SB connectors are Color Keyed
A unique feature of the SB Series connector housings are that they are keyed to only mate with the same color housing. For example, a gray color will only connect with the same gray color SB housing. The Red color will only connect to a red colored connector, etc. For SB350 there are no color mating exceptions.

This feature can be used to color code different voltages or systems and prevent accidental connection.

Gauge Option
SB Series connectors are available in a wide range of gauge contact options. It is important that the correct gauge option is chosen to match your cable selection. All gauges shown throughout the Powerwerx website are American Wire Gauge (AWG).

SB connectors are both genderless and polarized connectors
SB connectors are genderless, meaning the supply and load connectors are the same. Since there are no male or female parts, all SB connectors mate with themselves.

SB connectors are polarized, meaning the design is unique to prevent accidental reverse polarity connection. Only the positive (+) can be connected to positive (+) and negative (-) can be connected to negative (-). Connections can be quickly made and remade sightlessly or in the dark.

The Anderson SB Series connector family
The SB family spans a range of sizes covering up to 350 amps and accepting a different gauges of wire from 10 thru 4/0 AWG. Here is a size comparison diagram for the 50, 120, 175, 350 amp SB Housings:

High current rating, low resistance
The size of the wire a SB contact will accept is the primary limitation of their ability to carry a load. SB connectors will safely handle higher loads or surges, please read the linked data sheets (PDF) for additional information.

The contacts are made of highly conductive silver-plated copper for minimal contact resistance at high currents. The average contact resistance is 500 micro-ohms.

Flat wiping contact system
This system allows for minimal contact resistance at high current. The self-wiping action cleans contact surfaces during connection/disconnection. The contacts are rated at 10,000 no-load connect/disconnect cycles. When two pairs are mated together, it takes approximately 15 pounds of tension to pull them apart.

Stainless steel spring
Good connectors should not lose contact tension under use or vibration. SB connectors use a stainless steel spring which applies 50 lbs. of pressure to hold the silver-plated copper contacts firmly together and maintain constant contact. This is ideal for frequent connect/disconnect cycles. Other cheaper connectors simply depend upon soft copper that eventually spreads apart and becomes loose.

Durable polycarbonate housing
The SB insulated housings use a durable, high impact-resistant, high temperature polycarbonate plastic with a UL94 V-0 flammability rating. The connector design allows air to flow through the housing, assisting in cooling.

Additional accessories include handles, boots and dust covers
A variety of SB accessories are available including weather resistant dust caps, corrosion proof safety boots, connector handle kits, strain relief cable clamps and more.

Solar Power, Winch, and jumper cables By Guest

the trick with jumper cables: put an SB350 near the battery of every vehicle. cut the clamps off a jumper cable, leaving 18". put SB350s on all ends. you get a way to equalize the batteries of two vehicles without opening the hood or using clamps, you can jump a random strangers vehicle, but if someone asks to borrow them: hey, man, you need to have one of these wired up to your battery, man...

Solar power: gray SB50s from panel array to the solar generator. can't mix things up and plug the whole house array into the solar generator. SB175s mounted back to back, flat sides touching, lets me swap out batteries for the solar generator in seconds

Winch: SB350s make the car hauler winch on a trailer hitch removable. Dual Group 65 batteries make it a major jump start cart. The 8000 pound winch allegedly pulls 525 amps. The SB350s do not get hot.

Jumper cables By Guest

I use these to split my jumper cables in two. This allows my family members and me to check clamps on both ends for proper polarity and not be standing near either battery when last connection is made. I also made up a 16' extension to go in the middle of my cables for a total length of 36' allowing me to jump from the front to the rear of my 4dr long bed pickup or aid winch battery on my trailer. My cables use solid copper wire but the rest of my family's cables use copper coated aluminum wire and these connector's worked great.
