Because solar panels generate dc electricity, only terminal blocks that have passed a partial discharge test for dc voltage are suitable for safe use in photovoltaic systems.
Are terminal blocks safe?
Even thou other solutions do exist on the market for 1500V DC, the terminal blocks are one of the safest and most reliable way for connecting electrical circuits inside PV panels, combiners and central inverters,” said Gael Grenat, Head of Global Product Management for TE's ENTRELEC products.

What are Pi-spring terminal blocks?
ABB has launched a new range of PI-Spring terminal blocks for photovoltaic installations that make connections faster and simpler. ABB's patented connection mechanism is up to 50 percent faster than terminal blocks with screw clamp or busbar connections.
What is a ZK-PV terminal block?
The ZK-PV range of terminal blocks aims to make connecting photovoltaic systems quicker and more reliable. The smart two-in-one connection gives installers more flexibility, real time savings and higher quality results.
What are PV rated DIN rail terminals?
IMO's range of PV rated DIN Rail Terminals (PV Terminal Blocks) are 1000V rated up to 232 amps, and are constructed from UL94-V0 materials for optimum safety and fire-retardance. The whole range carry UR and cUR approvals (File number: E244285) and offer up to 95mm² wiring capacity.
The PI-Spring range have voltage of 1,500VDC (IEC)/1,000VDC (UL), complementing the existing 1,500V offering including DBL distribution blocks and SNK screw power terminal blocks ZS150/ZS240. The ZK-PV range of terminal blocks aims to make connecting photovoltaic systems quicker and more reliable.
To group more than two circuits, several ZK10PV terminals (10mm² / 6AWG) can be interconnected. The terminal blocks use proven ABB technologies and components, upgraded to accept 1500V DC voltage, to guarantee higher levels of safety and creepage distances.
