The 029045507 is a three-level, spring clamp feed-through terminal block designed for compact wiring solutions. It accommodates solid wires from 0.14 to 4 mm² and stranded wires from 0.14 to 2.5 mm², with UL/CSA ratings for 24-12 AWG and 24-14 AWG wire sizes. The block has an IEC voltage rating of 500V and a current rating of 20A, while its UL/CSA ratings are 150V and 16A respectively. A wire stripping length of 9.5 mm is required for proper connection. This three-level design is particularly useful for sensor wiring and other applications where panel space is limited, allowing for efficient and organized connections.
