Anderson connector – 120A – gray
Anderson-type high-current quick connector with 120A rating, grey color-keyed housing, max. 600 V DC rated voltage, silver-plated copper contacts and durable industrial construction. This 120A version is the larger Anderson size used by EnergonX, and it can also be integrated into mixed-color systems via a grey-to-red adapter cable.
- Connection principle: genderless, quick-connect and quick-release design
- Color keying: only same-color, same-type pairs mate directly
- Size: the 120A version is physically larger than the 50A version
- Typical cable range: approx. 16–25 mm²
- EnergonX relation: PowerBox units are typically fitted with red 120A connectors, but grey configuration can also be ordered
- Flexibility: later replacement or an adapter cable between different colors is possible
Recommended use: larger DC connections • PowerBox-to-battery links • boat • motorhome • winch • solar and UPS systems
- Product code:
- EX-C-A120-SZ
Larger high-current DC connection with grey mechanical keying
The Anderson 120A grey connector provides a quick, safe and durable solution for connecting batteries, inverters, DC distribution units, larger mobile power systems and custom PowerBox connections.
This version is the larger Anderson size used by EnergonX, generally suitable for approx. 16–25 mm² cable. The grey housing defines the connector keying, which means it mates directly only with another grey connector of the same type. Since EnergonX PowerBox units are typically fitted with red connectors, a grey system often requires a dedicated adapter cable or custom configuration.
What is it for?
For larger DC connections, PowerBox-to-battery links, charging, quick disconnect, and use in boats, motorhomes, winch systems, mobile power setups and custom electrical systems.
Why is the grey color important?
The grey housing is not only visual marking. It defines the keying of the mating interface, so grey cannot be plugged directly into red or other different colors.
What if the PowerBox is red?
In that case, a custom build, later replacement, or the use of an adapter cable may solve the issue. Such a cable may have a grey connector on one end and a red connector on the other.

Why is it useful?
- Fast connection and separation, with the same housing principle on both sides.
- The 120A version is physically larger, making it suitable for more substantial DC connections.
- Low contact resistance thanks to silver-plated copper contacts.
- Polarity-marked, keyed design for safer installation.
- Durable industrial plastic housing and vibration-resistant retaining spring.
What should be known about the grey color?
- The grey color defines a specific keying, so it cannot be plugged directly into red.
- If the existing EnergonX system uses red connectors, that is not a technical obstacle, only a compatibility issue.
- In many cases, a suitable adapter cable is enough and the whole system does not need to be rebuilt immediately.
- Such an adapter cable may have a grey connector on one end and a red connector on the other.
- This allows two differently keyed systems to be connected through an intermediate solution.
Installation – quick guide
- Select a cable cross-section appropriate for the rated current.
- Crimp the contact onto the cable using a quality crimp tool.
- Snap the contact into the housing until it locks into place.
- Assemble the opposite side in the same orientation and with the same housing color.
- A fuse near the battery positive terminal and mechanical strain relief are recommended.
