What size are DIN terminal blocks? ›

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.

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 compact, DIN rail mounted relays are best suited for applications that require higher continuous load currents than miniature relays can carry and switch. They can withstand inrush currents or brief overloads without damage and allow for continuous load currents of up to 10 A.

The industry-standard 35-mm wide top-hat rail is today the most commonly used for mounting relays, circuit breakers, controllers and other types of electrical equipment. There are two types available, at 5mm or 7.5mm deep, with most of the extant and new mountable electrical component designs being of this type.

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.

Control and Automation: Din Rail Relays are used to control the flow of electrical current in circuits. They act as switches, opening or closing the circuit based on specific conditions or inputs. This enables the automation and control of electrical systems, making them more efficient and reliable.

There are a variety of Terminal Blocks used in the electrical industry as per application and circuit requirements like Standard Feed through Terminals, Multiple connection Terminals, Double Level & Triple Level Terminal Blocks, Micro Terminal Blocks, and Sensor Terminal Blocks, CT connection Terminals, Fuse Terminals, ...

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.

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.

Do DIN rails need to be grounded? ›

In general, a DIN rail is not designed to be used as a busbar. However, with grounding terminal blocks attached, a DIN rail can be used as a busbar for a chassis ground.

Identifying relay terminals is crucial for ensuring proper functionality in electrical circuits. Relays typically have four to five terminals: the coil terminals (commonly labeled 85 and 86), the common terminal (30), the normally open (NO) terminal (87), and sometimes the normally closed (NC) terminal (87a).

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.

Firstly, they have a smaller space between the pins, and the connectors can also have two different pin spacings: 10 mm and 11 mm. The 11 mm DIN connectors have three flat blade contacts and are the most common. The 10mm DIN connectors have one flat blade and two U-shaped pins pointing outward, as seen in figure 3.

The outer diameter of the metal shell of a DIN connector is 13.2 mm, and the 1.45 mm pins are all positioned at the circumference of a virtual circle with a diameter of 7 mm at the centre of the connector. Depending on the layout, the angle between the pins is 45°, 60°, 72° or 90°.

The DIN sizes come in a full size DIN of 480x250mm, half sizes 240x250mm, quarter sizes 120x250mm and three-quarter sizes 360x250mm.
