Benefits of RETTBOX® S
All our electrical connection solutions are patented to guarantee safety for end-users. Safety Features Include:
- Self-ejection
- Ingress protection
- Poor weather and temperature resistance
- High-quality materials
- Protection from live parts (IPXXB)
RETTBOX® S ensures self-ejection, preventing failures to the electrical installation.
RETTBOX® S, has a compact size to optimize the assembly onto the vehicle.
Easy mounting of the RETTBOX® S makes assembly, use, and maintenance easy providing both time and cost savings for the vehicle body converter as well as the end-user.
Vehicle body converters save on metal cutting and drilling. Vehicle body converters also save with threaded inserts installation, simple wiring, and box mounting.
The end-user can easily plug-in with only one hand and experiences the following advantages:
- Reduced internal volume: space saving and easy wiring.
- Small flush mounted plate on the vehicle body (.62 in): conveniently designed for simple integration.
RETTBOX® S was designed to offer a flush-mounted plate recessed into the vehicle body frame. Discrete low profile with rounded corners to avoid impact damage and injury.
Our black reinforced thermoplastic is light, easy to install and provides a swivel lid that guarantees IP54 protection.
We incorporated the benefits of our 40 years of expertise to provide you with the most reliable and durable product available to date in the market. Materials used (stainless steel, reinforced thermoplastics) ensure excellent resistance to impacts (IK08), UVs, temperature variations (-40°F/+140°F), and high electric isolation.
- Tested up to 10,000 mechanical make and break cycles.
- Proven expertise amongst the most recognized vehicle manufacturers and converters (ambulances, electric/autonomous vehicles, refrigerated trucks, etc.).
- DECONTACTOR™ technology is utilized in more than 180 countries worldwide.
- RETTBOX® S is compatible with any type of battery charging station.
Spring-Loaded Butt Contacts Provide for Thousands of Consistent and Reliable Connections.
RETTBOX® S uses spring-loaded, butt-style contacts similar to those used on contactors and switchgear. Their end-to-end mating provides a stable connection. The spring-loading delivers optimal contact pressure and the integrity of the electrical connection is maintained over thousands of operations.
- Spring-loaded butt contacts automatically compensate for manufacturing variations, eliminating contact mating and connection quality problems caused by the dimensional variations of other contact designs.
- End-to-end mating eliminates the effects of wear inherent with sliding contacts.
- Consistent spring pressure eliminates overheating caused by poor contact force.
The performance and design advantages of spring-loaded butt contacts make them a superior choice for providing consistently safe and reliable connections.
Silver-Nickel Contact Material Provides Superior Conductivity
We use solid silver-nickel contact surfaces on our RETTBOX® S. The contacts’ 85% silver and 15% nickel composition combines the durability of nickel with the excellent conducting properties of silver.
- Silver-nickel contacts provide significant advantages over the brass materials used on most other types of plugs and receptacles.
- Silver-nickel maintains low contact resistance and superior electrical properties even after oxidation and tarnishing.
- Silver-nickel withstands arcing very well and only welds at extremely high pressure and temperature.
- The hardness of nickel gives the silver-nickel contacts excellent wear resistance.
Silver-nickel performs well in and withstands wet and corrosive environments. The combination of silver-nickel contacts with a spring-loaded butt-style design makes the contacts ideal for repetitive making and breaking of connections under load.
Limitations of Brass as a Contact Material
- Brass is not arc resistant, so it is not suitable for repeated making and breaking under load.
- Brass is a soft material and wears rapidly, degrading the operational characteristics of the contact.
- Brass oxidizes easily, preventing it from performing well in wet or corrosive environments.
- The contact resistance of brass increases rapidly due to tarnishing that occurs during normal use.
