Overview

The Mersen FSPDB2A Finger-Safe Power Distribution Block (SKU: FSPDB2A) redefines safety and efficiency in power distribution. Engineered for demanding electrical applications, this 1-pole block offers an IP20 level of finger-safe protection, eliminating the need for additional covers or custom shielding. Its fully insulated design ensures touch-safe isolation of live parts, with recessed termination screws and wire openings meeting IEC 529 standards. The FSPDB2A is designed for quick and easy installation, snapping directly onto a 35mm DIN rail, significantly reducing installation time and costs. Its compact, modular design allows for flexible configurations, enabling users to build smaller and higher-density panels. This model supports a maximum voltage of 1500VAC/DC and a current rating of 175A. The wire range for aluminum and copper conductors is 2/0 AWG to #14 AWG (70-2.5 mm²), with one opening per pole. It also features captive termination screws, preventing loss during installation. The FSPDB2A is UL Recognized Component (File E73571) and CSA Certified (Class 6228, File 69363), and CE Marked, ensuring compliance with stringent industry standards. It is ideal for splicing cables, splitting primary power into secondary circuits, or providing fixed junction tap-off points. Available accessories, such as assembly pins for multi-pole configurations, cap plugs for unused openings, circuit identification markers, and end anchors, further enhance its versatility and safety. The Short Circuit Current Rating (SCCR) is 100kA. Mersen FSPDBs provide a safe, convenient, and efficient solution for modern electrical panel building.
