Anderson Power Products SB350 SB Series 350 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.

Customer Reviews

I own and use these connectors By Guest

Not sure how anyone can give less then perfect rating and then not tell why it's not perfect. Shame on them.
I use these for a removable 12,000 lb winch and they have given no problems. These are self cleaning when you use them and provide ease of use and a great connection.

Excellent product By Ryan

I have been using Anderson 350 Ampere Powerpole sets for decades on my 4X4's and rally car.
I use them for custom made jumper cables as well as on my winches on my Jeep. (Both front and rear)
The attachable handle make them very easy to disconnect when attaching or removing the jumper cables or when removing/reinstalling the winches when needing access to remove the grille, etc.

For High Current Ops By wa4bxc@arrl.net

Installed one near alternator. Use for special jumper cables, and 8000 lb winch. Also use the optional cover. There's never any road contamination in connector.
Polarity of connection is always correct.
