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.
Gael Grenat, global product manager for ABB’s Connection business, said: “The solar power industry looks to ABB for innovations to make photovoltaic installations more robust, durable and cost effective. The ZK-PV range of terminal blocks makes connecting photovoltaic systems quicker and the commissioning work more reliable. The smart two-in-one connection gives installers more flexibility, real time savings and higher quality results.”
The new ZK-PV range is for large commercial and utility-scale photovoltaic installations with a rated voltage of 1500V DC (IEC) / 1000V DC (UL). ABB’s unique design gives installers two different ways to connect wires quickly and securely. A Push-In mode lets installers just push solid wires into the terminal – ABB’s patented design automatically clamps the wire to create a strong, reliable connection. In Spring Mode, non-prepared, stranded wires can be inserted just as easily. The installer just needs to slide a screwdriver into the adjacent slot, insert the wire and the connection is secure.
The ease-of-use and flexibility of ABB’s PI-Spring technology helps significantly reduce connection times. In tests, the design was up to 50 percent faster than terminal blocks with screw clamp or busbar connections.
The ZK-PV range for photovoltaic installations is as compact as the rest of the PI-Spring terminal block range, adding just 2mm to the unit’s depth. To differentiate positive and negative poles, two colors are available: grey and blue. The distribution blocks are suitable for cables with maximum cross-sections of 10mm² / 6AWG and 16mm² / 4AWG. The range provides two and three connections so that two circuits can be grouped in parallel in one line. To group more than two circuits, several ZK10…PV 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. ABB’s PI-Spring products have a long track record for quality and performance in harsh environments, providing robust resistance to high heat levels and temperature variations, humidity, solar UV, vibration and shocks. The specialist metal and plastic materials used in their construction are common in rolling stock and railway applications.
ABB technologies are widely used in solar applications. The new range complements the popular DBL distribution blocks, MC4-EVO2 PV connectors and SNK screw power terminal blocks ZS150 / ZS240, which are already rated 1500V.
