Frequently Asked Questions (FAQs)

1. What is a ground terminal block?

Grounding terminal blocks are used to mechanically and electrically connect wires to the DIN rail by means of a conducting clamping foot. In this way, the DIN rail can function as a ground bus bar. Grounding terminal blocks are molded in green and yellow per international standards.

2. What is a terminal block circuit?

Terminal blocks are connectors that terminate a single wire and connect it to a circuit or other system. Terminal blocks come in a range of shapes, sizes and ratings, but always terminate a single wire (single pole) and are never multi-pole.

3. Are connector blocks safe?

Overheating and damage to a terminal block can occur when operating at too high of a current, which can present critical safety concerns. In general, it is recommended to select a terminal block with a current rating of at least 150% of the system's expected max current.
