Universal terminal clamp OTH240-4 with two mounting holes 4xAl/Cu 50-240 mm² 1600A, 1000V MAC4240A15

Universal solution for electrical installations

The OTH240-4 universal terminal block enables the direct connection of copper and aluminum conductors to distribution devices in electrical installations with high current loads. The product allows for the connection of two, three, or four conductors with a cross-section of 50-240 mm² without the need for cable lugs, which significantly simplifies the installation process.

The terminal design is engineered for economy and compactness, occupying minimal space in the switchboard while maintaining full functionality.

Design and technical parameters

The OTH240-4 terminal is manufactured in a single-pole configuration with four independent terminals per pole, allowing for flexible wiring according to individual installation needs. Direct mounting enables fast and secure attachment of the device in the switchboard using two mounting holes.

The device supports two types of electrical connections: a screw connection for standard conductor fastening and a bolt connection for applications requiring rapid disassembly or frequent configuration changes. The design is not transparent and does not require an additional cover plate.

Operating parameters include a rated current of 1600A at a rated voltage of 1000V. The terminal does not have insulating elements or Ex-e explosion-proof certification.

Practical advantages and compatibility

The main benefit of its universal nature is the ability to use one type of terminal for different types of conductors - both stranded conductors without ferrules and multi-core cables. This eliminates the need to stock a diverse range of cable accessories.

The compact, small-sized design facilitates wiring in tight switchboard spaces, while simultaneously ensuring easy access to connection points during servicing or installation upgrades. The lack of requirement for cable lugs reduces material costs and installation time.
