Terminal block electro base E-412221412, 2×0.2–4.0 mm² universal

Universal terminal block electro base E-412221412, 2×0.2–4.0 mm² universal is a compact insulated connector designed to join, branch or terminate two conductors with cross-sections from 0.2 to 4.0 mm². The product is intended for use in control panels, distribution boards and electrical equipment where a secure mechanical and electrical connection is required in a space-saving form factor. The terminal block supports signal and power wiring and provides reliable insulation and contact stability for repeated handling and maintenance.

Advantages

The terminal block offers a wide conductor range that accepts fine-stranded and solid wires, reducing the need for multiple block types. Its insulated housing ensures protection against accidental contact and helps maintain clear separation between adjacent connections. The compact footprint facilitates high-density wiring layouts while retaining reliable mechanical clamping and consistent electrical contact. Material choices and construction support long-term stability under typical installation conditions.

Suitable for

• Wiring and branching in electrical distribution boards
• Connection points inside control panels and automation cabinets
• Signal and low-voltage power connections for machinery and equipment
• Field splicing where compact, insulated termination is required

Key specifications

• Number of conductor positions: 2
• Accepted conductor cross-section: 0.2–4.0 mm²
• Wire types supported: solid and fine-stranded conductors
• Connection method: screw or clamping (universal clamping mechanism)
• Insulating housing: compact, impact-resistant polymer
• Mounting: DIN-rail or panel-compatible mounting profile (compact form)
• Rated usage: suitable for signal and low-voltage power wiring

How to use

Strip the conductor insulation to the length recommended for the terminal block, insert each conductor into its respective opening and tighten the clamping screw or mechanism until the conductor is held firmly without deformation. Verify mechanical retention by a gentle tug on each wire. For fine-stranded wires, use an appropriate ferrule if required by local practice or installation standards. Arrange adjacent blocks and route wiring to maintain clearances and avoid mechanical stress on the terminated conductors.

Usage recommendations

Follow applicable local electrical codes and standards during installation. Ensure the conductor cross-section matches the specified 0.2–4.0 mm² range and confirm tightening torque recommended by installation guidelines. Use ferrules for fine-stranded wires where required, and perform regular inspections of connections in installations subject to vibration or thermal cycling.
