What are DIN rail terminal blocks?
DIN rail and channel terminal blocks are rack or box mount connection points for securing two or more wires to a circuit or power bus. Certain types may include a single or dual disconnect fuse or switch feature, feed-through capability, grounding, built-in indicators and resistors, isolation and circuit protection.
How do you select a terminal block?
A good rule of thumb is to select a terminal block that has a current rating of at least 150% of the system’s expected maximum current. The voltage rating should also be greater than the maximum system voltage. When thinking about this, voltage surges must be taken into consideration to prevent damaging the connection.
How many contact points are on a terminal strip?
Each terminal strip has 60 rows and 5 columns of contacts on each side of the center gap. Each row of 5 contacts is a node. You will build your circuits on the terminal strips by inserting the leads of circuit components into the contact receptacles and making connections with 22-26 gauge wire.
What does Phoenix Contact do?

What amp terminal block should I use?
When looking for a terminal block, be sure that the chosen block can, in fact, handle the current that you expect to use plus 50 percent more. For example, if an expected current of 2 A is to be drawn from a block, then a terminal block with a current rating of 3 A would be sufficient.
What are the types of terminal blocks?
Types of Terminal Blocks
- BARRIER STRIPS.
- MODULAR TERMINAL BLOCKS.
- PCB TERMINAL BLOCKS.
- POWER DISTRIBUTION BLOCKS.
- TERMINAL BLOCK & STRIP ACCESSORIES.
Are terminal blocks connected?
Terminal blocks are connectors that terminate a single wire and connect it to a circuit or other system. Terminal blocks come in a range of shapes, sizes and ratings, but always terminate a single wire (single pole) and are never multi-pole.
How do you connect wires to terminal blocks?
Terminal blocks at a glance
- Terminal blocks are connectors that terminate a single wire and connect it to a circuit or other system.
- The most common connection method for terminal blocks is the use of a screw, wherein wires are inserted and then clamped down with the use of a single screw.
- Screw terminals.

What size is a terminal block?
Common industry pitches would be, but are not limited to, 2.54 mm, 3.81 mm, 5.0 mm, and 7.62 mm.
What are contact blocks used for?
Terminal blocks increase safety by grounding, isolating, and protecting the other components in the electrical circuit. Terminal blocks are available with finger-safe connections to prevent electrical shock. And, terminal blocks can also provide test points, which add even more safety to the circuit.
