Outdoor Waterproof Switch-Terminal Junction Box
KRIPAL offers high-performance IP54/IP65 terminal junction boxes (D and K series) designed for secure electrical connection and distribution in industrial and outdoor settings. These enclosures are constructed from impact-resistant thermal plastic for a fashionable, durable appearance and utilize corrosion-resistant V2A metric screws with a large pitch for faster, easier installation. The range covers various sizes from 88x88x53mm to 200x160x98mm, featuring flexible cable entry options (ESM20 to ESM40) and advanced five-position terminal support for versatile wiring. Note that compression glands must be used to achieve an IP65 rating. They are ideal solutions for cable junctions, sensor connections, and small-scale distribution.

A terminal junction box is a weatherproof enclosure that provides a protected space for electrical connections, whether simple cable-to-cable terminations or multi-cable distribution through advanced five-position terminal blocks. The IP54/IP65 rating protects internal connections from water, dust, and mechanical impact, making the junction box suitable for outdoor installation and indoor wet or dusty areas. Manufactured from impact-resistant thermal plastic with corrosion-resistant V2A screws, this selection guide covers enclosure material, size, IP rating, cable entry configuration (such as ESM20 to ESM40 inserted-type pipe connections), and terminal support options.
Terminal Junction Box Series Technical Specifications
Enclosure Material Selection: ABS vs Polycarbonate
The D and K series terminal junction boxes are crafted from expensive impact-resistant thermal plastic, creating a fashionable and attractive look. They feature solid covers fixed by corrosion-resistant V2A metric screws with a large screw pitch, reducing fastening effort to two-thirds of normal. Note that transparent covers are not supported for this series.
IP Protection Level: IP54 and IP65
The enclosures deliver IP54 or IP65 protection based on setup needs. To achieve a full IP65 rating, compression glands must be used when environmental conditions require it. This design reliably safeguards internal components against dust and moisture in harsh settings.
Cable Entry and Terminal Technology
The base provides pre-formed pipe connections (inserted type, such as ESM20 to ESM40) and metric conductor input holes on all sides for flexible routing. Inside, the boxes incorporate advanced terminal technology alongside flexible support positions for five-position terminals.
Installation and Application
Engineered for efficiency, the units utilize V2A metric screws to streamline mounting and maintenance. They serve as reliable solutions widely deployed for standard cable junctions, sensor connections, and compact electrical distribution tasks.

Cable Connection Protection for Outdoor, Industrial and Infrastructure Applications
KRIPAL D and K series terminal junction boxes provide weatherproof enclosures for electrical connections in industrial and infrastructure settings. From compact sensor connections to larger distribution setups, these boxes protect electrical terminations from water and dust.
Industrial Sensor and Actuator Connection
Factory automation systems use compact junction boxes to connect field sensors and actuators to control systems. The box houses advanced five-position terminal blocks for secure wiring, with the IP54/IP65 enclosure protecting connections from workshop dust and moisture.
Street and Area Lighting Circuit Junction
Lighting circuits use junction boxes at the base of columns for connecting supply and luminaire cables. The impact-resistant thermal plastic enclosure withstands outdoor exposure, featuring corrosion-resistant V2A screws and reliable terminal support.
Solar PV Array Cable Junction
Photovoltaic installations use junction boxes for DC cable connections. The durable thermal plastic enclosure withstands rooftop or ground exposure, and the IP54/IP65 rating protects connections from rain and dust.
Building Services Cable Distribution
Commercial buildings use these boxes for cable distribution in plant rooms and external walls. They house advanced terminal blocks for secure terminations, protected by robust enclosures utilizing V2A metric screws.
Water and Wastewater Plant Field Connections
Water treatment plants use junction boxes for field instrument and actuator connections in demanding areas. The enclosure protects internal wiring from moisture and humidity, utilizing flexible pipe connections (ESM20–ESM40).
Specify Your Junction Box Requirements
- Application Review: Our engineers review your cable and environment specifications and recommend the D or K series box size and impact-resistant thermal plastic material.
- Custom Machining: We can pre-machine pipe connections (ESM20–ESM40) and mount five-position terminals at the factory for your convenience.
- Bulk Supply: Source D and K series enclosures in volume for your project or ongoing requirements, featuring corrosion-resistant V2A metric screws.
KRIPAL Terminal Junction Box Manufacturing: Weatherproof Connection Protection
KRIPAL terminal junction boxes are manufactured in a dedicated fabrication facility where the IP54/IP65 thermal plastic enclosures are molded, advanced five-position terminals are fitted, and pipe connections (ESM20 to ESM40) are applied. Each junction box undergoes strict quality verification for global cable connection and distribution applications in industrial and outdoor environments.
Enclosure Molding with Integrated Features
Enclosures are injection-molded from expensive impact-resistant thermal plastic, forming a fashionable and attractive appearance with integrated mounting features and secure sealing interfaces. They utilize corrosion-resistant V2A metric screws with a large screw pitch to make handling and screw fastening two-thirds of the normal one.
Terminal Block Assembly and Support
Terminal blocks are fitted utilizing advanced terminal technology and flexible support positions for five-position terminals. Each unit is designed to provide optimal internal space and secure positioning for reliable wire and cable management.
Cable Entry and Sealing Options
Cable entry utilizes pre-formed pipe connections (inserted type, such as ESM20, ESM25, ESM32, and ESM40) and metric conductor input holes on all sides. Compression glands must be used to achieve a full IP65 rating when environmental conditions require it.
Terminal Support and Quality Verification
Quality checks ensure that terminal support positions, metric screw fastenings, and molded thermal plastic structures meet high-performance standards for secure electrical accessory applications.
