Product Overview
A junction box with terminal block reduces the amount of terminal-selection and mounting work required for a field connection point. The BOWO catalogue shows several terminal-box configurations with defined enclosure dimensions, cable inlet/outlet counts and current ratings.
The enclosure series is specified as IP66 and IK08 and is listed with CE and RoHS. Current rating and cable-entry arrangement are model-specific and should be matched to the actual circuit requirements.

How to Select a Terminal Junction Box
- Current requirement: choose a model whose listed current rating matches the circuit design.
- Number of cables: select the inlet/outlet arrangement that matches the wiring topology.
- Conductor size: confirm compatibility with the installed terminal block before ordering.
- Environment: verify IP66 is suitable for the complete installation.
- Space and maintenance: allow sufficient clearance for conductor termination and service access.
Select by Current and Cable Layout
The enclosure should be selected around both electrical load and wiring arrangement. A higher-current model is not automatically the best choice if the cable-entry layout does not match the installation. Compare the required current rating together with the number of incoming and outgoing cables and the available mounting space.
See the full terminal block junction boxes range for other current ratings and enclosure sizes.
Applications
- Field wiring junctions
- Equipment connection points
- Branch connections between incoming and outgoing cables
- Industrial control and auxiliary power wiring
- Outdoor electrical connections where the selected IP66 assembly is appropriate
For general enclosure protection selection, see the IP-rated waterproof junction box selection guide.
Customization
If the standard cable-entry arrangement does not match the project, provide the required gland positions and cable directions. Custom openings are listed as an available option in the catalogue.
