DC String Combiner Box Fused up to 1000V

Ideal for commercial PV systems of 3 and 4 string design, the PV combiner box from IPD provides overcurrent protection as well as DC isolation. Fitted with the latest Telergon DC isolator this 4-string combiner is easy to install and quick to connect.

Switching Designed around the latest high current DC switch from Telergon, ZFV55, the IPD combiner box includes multiple knock-out entries as well as high UV stability. The ZFV55 is tested to meet the latest International Standard IEC 60947.3 with switching capability of DC21B. The ZFV55 complies with the requirements of AS5033 2014.

Overcurrent The Mersen PV fuse links used in this combiner box are tested to the latest fuse Standard IEC 60269.6. This Standard was released in 2011 and is specifically included in the fuse standard to test the cyclic loading and long term reliability of fuses when used in photovoltaic systems.

Enclosure The high-quality Hensel enclosure products are made of material that is UV, impact, dust and waterproof, self-extinguishing, flame-retardant, halogen and silicone-free. This product and quality philosophy has made Hensel the world Number 1 brand for electrical distribution solutions in difficult environments
