ETI ESC-CBC.4B Neutral Terminal Block, Single Level, 4 mm², 12 kV, Blue 003903045

In electrical distribution, neutral conductors need a reliable, clearly identifiable connection point that can withstand high impulse voltages. The ETI ESC-CBC.4B neutral terminal block provides a dedicated single-level connection for neutral wires up to 4 mm², with a blue housing for instant identification according to wiring conventions.

Who is it for

Electricians and panel builders who install DIN rail terminal blocks in control cabinets, distribution boards, or industrial enclosures. It suits applications where a separate neutral terminal is required for clarity and safety.
