Small junction box from Tyco Electronics for PV industy

Tyco Electronics has introduced the SOLARLOK slim junction box, a small junction box for PV industry. The junction box measures 15.5 mm by 52 mm and distributes DC power to a solar panel in a convenient, compact design that offers low visibility on the back of a panel. This product is TUV-approved and offers a 20-year product-life performance.

The SOLARLOK is suggested for two-rail crystalline PV modules and two-rail thin-film PV modules, with a 12-Amp current rating for crystalline applications and a 3-Amp current rating for thin-film applications. The junction box assembly includes solar-rated cables available in various lengths, IP67-rated SOLARLOK connectors, which produce an audible click to ensure proper installation and include a locking latch feature that meets code requirements. The junction box assembly also includes a spring clamp for termination of the foil leads, which clamps to the contact rail inside the box for increased reliability and ease of termination. This feature also eliminates the labor-intensive task of soldering.The diodes are offered in multiple current ratings, ranging from 3 to 12 Amps. The SOLARLOK slim junction box does not require potting eliminating the cost and mess of using potting material to seal the inside of a box from moisture. In addition, the housing lid utilizes two latches to secure attachment to the lower part of the box
