Eaton’s Bussmann business, working in critical circuit protection, power management and electrical safety, has been awarded TUV Rheinland certification for its combiner box range. It is the first manufacturer to gain full certification for both product safety and electromagnetic compatibility (EMC) for this type of product.

To achieve the TUV-Type Approval Mark the combiner box underwent comprehensive review including testing for electrical safety, vibration, damp and dry heat, as well as mechanical reliability. The EMC-Mark Approval also certifies that the product meets the requirements in regard to electromagnetic compatibility for emissions and immunity.

In addition to the comprehensive testing the TUV certification also included factory inspection and audit ensuring the processes and procedures used for manufacture are robust and consistent.

Commenting on the achievement, Simon Bircham, product manager said: “Overall this is a lengthy process which demonstrates our commitment to designing and manufacturing safe and reliable product for use in the harsh environmental conditions of PV installations.”

Eaton’s Bussmann combiner box range sets new standards in protection, switching and monitoring of PV systems. Designed for system voltages from 600V DC to 1,000V DC the range combines the latest in overcurrent, overvoltage and monitoring technology in one robust, custom-built package.
