FAQs

What are DIN rail terminal blocks? ›

DIN rail terminal blocks are an important component of electrical cabinets and industrial racks (assemblies), helping to protect and connect complex equipment. They have become a standard component in electrical systems used across industry. Examples include: Telecommunications equipment.

Fused DIN rail terminal blocks are widely used in industry and offer more protection from overcurrent than non-fused DIN rail terminals. They are usually used to protect sensors and relays. However, both fused and non-fused can be used for applications such as: Energy management.

These terminal blocks mount on standard 35 x 15mm and 35 x 7.5 mm DIN rails and are design to meet world wide standards. The AVK terminal blocks come in all wire ranges and no pre-treatment of the wire is necessary, even for stranded wire.

In this context, 'DIN' is an acronym that stands for Deutsche Institut für Normung, which translates into English as 'German Institute of Standards'. The now-familiar rack-mounting system we see supporting components of all kinds in many industrial settings was first devised by the Germans in the late 1920s.

Standard DIN Rails are available in 35mm (7.5 and 15mm deep), 32mm and 15mm widths and are supplied in 1 m (3'3") and 2 m (6'6”) lengths. Upon request they can be cut to cus- tom lengths and punched with cus- tom holes or perforations.

Like most electronic circuits, the first items to evaluate are the circuit parameters of the application, including the nominal current, the system voltage, and the number of circuits needed. The current and voltage rating of the terminal block needs to be above the nominal current rating and system voltage.

A terminal block consists of a modular housing with an insulated body that secures two or more wires together. Terminal blocks—also referred to as terminal connectors, connection terminals, or screw terminals—are used in a wide array of applications where electrical systems need to be safely connected.

Terminal blocks may also be grouped by application or type of device they connect. Ground circuit terminals are used to ground components or systems. They are typically interchangeable with standard terminal blocks and can be inserted into a block as needed.

As many as it will physically hold. Some terminal blocks can hold dozens of wires; look inside any breaker box. Do not exceed the voltage or current safety of the terminal block. But as long as you keep within those, as many wires as will fit.

Universal mounting in all three commercially available rails EN 60 715 TH35, TH15 and G32 DIN rails. For 73mm and 108mm width PCB size. Available with custom length & in preassembled kit form to save time.

What is the purpose of terminal blocks? ›

Terminal blocks are connectors used to secure two or more wires to each other (wire-to-wire) or to a PCB (wire-to-board). They consist of an insulated body within a modular housing.

Terminal boxes are used for particular connections when there is no room for future extension or where the expansion of connections is not required in the future. On the other hand, a junction box has a small footprint and lots of working area. New connections might also be planned for future development.

One common issue associated with terminal blocks is Loose Connections: Over time, terminal screws can become loose due to vibrations or thermal cycling. Loose connections can lead to intermittent electrical contact, increased resistance, and potential overheating.
