## Long description

Branching terminal block No name model E121YY-SI003 is a compact 4-way connector designed for 2.5 mm² conductors. It provides a practical solution for splitting or joining electrical conductors in confined spaces. The unit features a black insulating housing and screw/clamp interfaces that ensure a secure mechanical and electrical connection for building wiring, lighting circuits and control panels where a small multi-connector is required.
Advantages
The 4-way configuration permits neat distribution of one input to multiple outputs or combining multiple inputs into a single feed without bulky wiring. The black insulating body offers basic protection against accidental contact and helps with visual identification in installations. Screw or clamp-style terminations provide reliable retention of 2.5 mm² conductors and stable electrical contact over time when properly installed.
Suitable for
 Branching and joining circuits in residential and commercial building wiring
 Lighting circuit distribution and fixture connections
 Control panels and terminal blocks where space is limited
 Temporary or permanent junctions for 2.5 mm² conductors
Key specifications
 Conductor capacity: suitable for 2.5 mm² solid or stranded conductors
 Number of ways: 4-way branching configuration
 Housing: black insulating material for electrical separation
 Termination type: screw or clamp-style interfaces for secure connection
 Mounting: compact form factor for use in confined spaces or on DIN/rail-adjacent panels (where applicable)
How to use
Strip the conductor insulation to the recommended length for the terminal block, insert each conductor into its respective port and tighten the screw or clamp until the conductor is held firmly without excessive force. Ensure correct polarity and secure connections by performing a gentle pull test on each conductor. Use appropriate tools and follow local electrical regulations and safety practices when making connections. Verify continuity and insulation after installation before energizing the circuit.
Usage recommendations
Use the terminal block only with conductors of the specified cross-section and in dry, appropriately rated environments. Avoid over-tightening screws to prevent conductor damage and check connections periodically, especially in environments subject to vibration or thermal cycling.
