1546977-3

Terminal blocks, also known as barrier blocks, are widely used in electrical and industrial equipment as an efficient connection between circuit boards and wired electrical components. The modules can be inserted securely into standard electrical junction boxes, providing a safe and easily accessible junction point for multiple cables and wires.

The 1546977-3 terminal block, is used to connect two different electrical circuits, typically one lower voltage and one higher voltage. It is available with a UL listed, type 3R, or IEC 60947-7-2 rated enclosure and is suitable for use at 125V and 250V in hazardous location applications. The unit provides open and short circuit protection for DC and AC loads, and offers a maximum current rating of 25A.

The 1546977-3 terminal block consists of two sliding blocks embedded in an insulating material. Each block is linked by four internally wired contacts. The sliding blocks must be forced apart and the wires connected between them, the contacts are then released, which securely locks the two blocks in place. This force connection ensures a good electrical contact without the need of complex wiring.

Once installed, the 1546977-3 terminal block can be electrically connected and disconnected many times. It is constructed to be fire and temperature resistant, and to meet the requirements of NEMA and CSA certifications. Due to its rugged design, the 1546977-3 terminal block can withstand harsh environmental conditions, including vibration, shock, and dust and moisture contaminants.

In summary, the 1546977-3 terminal block is a robust and reliable connection module that is designed for use in electrical and industrial equipment, providing a secure and accessible junction point for multiple cables and wires. Its self-locking force connection ensures good electrical contact without the need of additional wiring, while its rugged construction makes the module suitable for harsh environmental conditions.
