Terminal Blocks - Barrier Blocks is one of the application fields and working principles of 1-1546657-1.

Terminal blocks are the backbone of an industrial wiring system, connecting field wiring to control cabinets. Technically, their primary task is to make electrical connections and they’re ideal for building reliable, economical field wiring harnesses, as well as for communicating within a star topology field wiring system. Most electrical connections in control cabinets are made between conductors and terminals on control systems, from the main to the field level, using terminal blocks.

Barrier Blocks are a type of terminal block that are designed to protect against unsafe electrical arcing in an electrical circuit. They are used to prevent damage and fires by containing electric arcs with a barrier material that prevents the arc from spreading to the surrounding area. This type of terminal block is often used in commercial and industrial applications to prevent electrical arcs from damaging sensitive or critical electrical equipment.

1-1546657-1 offers a wide range of features to provide superior protection against electric arc faults. It is certified to UL 1059 and meets all Lloyd’s Register electrical performance requirements, offering a terminal connection for 2-24 wires. This terminal block also provides a 0.2” mounting hole for fixed panel mounting.

1-1546657-1 provides a unique self-cleaning design which uses factory-set spring contact pressure to make positive contact with the wire. This ensures reliable connections and reduces the risk of arcing between wires. The terminal block also includes a safety shutter which prevents accidental contact with terminals, keeping people and objects safe from electric shock.

The 1-1546657-1 terminal block also offers an LED indicator which alerts users to any arcing that may have occurred in the circuit. An integral unplugging latch helps prevent accidental disconnection of the circuit in case of an electric arc fault. The terminal block also has an integrated transient suppression device which absorbs any voltage overshoots in the circuit, limiting the risk of equipment damage due to electrical spikes.

The 1-1546657-1 is the perfect choice for applications that require superior protection against electric arcs, providing reliable connections with ultra-fast response time. It is a reliable and economical solution for any industrial wiring system.
