What type of component is this?
This is a DIN-rail disconnect terminal block with test socket screws on both sides. It is designed for organised panel wiring where a circuit may need to be isolated and checked during installation or maintenance.
What is this terminal block commonly used for?
It is commonly used in control panels, switchboards and industrial electrical assemblies where conductors need a secure screw connection, clear terminal separation and convenient testing access.
Does it include a test connection?
Yes. The design includes test socket screws on both sides, which makes it easier to carry out circuit checks and measurements without disturbing the main wiring arrangement.
What cable sizes can it accept?
This terminal block is suitable for conductor cross sections from 0.14 mm² up to 6 mm² for solid and stranded conductors. It also supports ferruled conductors within the specified ranges, making it flexible for a variety of panel wiring tasks.
What are the rated electrical values?
The nominal rating is 500 V and 20 A. The maximum load current is stated as 16 A with a 6 mm² conductor cross section. For users reviewing approvals data, the listed UL, CUL and CSA figures are 600 V and 16 A.
What type of connection does it use?
It uses a screw connection. The screw thread is M3, the recommended stripping length is 9 mm, and the tightening torque range is 0.6 to 0.8 Nm.
How many connections does it have?
This is a single-level terminal block with 2 connections. That makes it suitable for straightforward line isolation and connection tasks on DIN rail assemblies.
What are the dimensions?
The terminal block has a width of 6.2 mm and a length of 57.8 mm. Its height is 73 mm on NS 35/7.5 rail and 80.5 mm on NS 35/15 rail.
Is it suitable for DIN rail mounting?
Yes. It is intended for mounting on standard NS 35 DIN rail profiles, including both 35/7.5 and 35/15 formats, which makes it suitable for many common enclosure and panel layouts.
What colour and material is it?
This component is black and uses PA insulating material. The insulation material has a UL 94 V0 flammability classification.
Can it be used with bridging accessories?
Yes. It is compatible with plug-in bridge options for cross-connections in the terminal centre, which can be useful where multiple terminals need to be linked neatly across a rail assembly.
Does it have recognised approvals?
Yes. The listed approvals include UL, CUL and CSA, along with DNV, GL and LR. This can be helpful for applications where documented compliance and recognised terminal data are important.
- Isolating individual circuits within control panels to simplify routine maintenance and fault finding.
- Creating clear disconnect points for field wiring in industrial automation cabinets.
- Providing a convenient terminal for testing and measurement thanks to test socket screws on both sides.
- Separating signal, control or low-power distribution circuits on DIN rail assemblies.
- Organising machine wiring where a compact, clearly defined disconnect terminal is needed.
- Building tidy marshalling sections for sensors, actuators and other panel-mounted devices.
- Managing feeder and branch connections in panel wiring where straightforward circuit interruption is required.
- Supporting commissioning work by allowing circuits to be checked, isolated and verified at the terminal.
- Using in process control enclosures for structured termination of conductors up to the stated connection range.
- Integrating into OEM equipment panels where space-efficient screw connection terminals are preferred.
