The 3031225 is a blue, single-level feed-through terminal block designed for DIN rail mounting. It utilizes a spring-cage connection method, accepting a conductor cross-section range of 0.08 mm² to 4 mm² (28-12 AWG). Key electrical characteristics include a nominal voltage of 800V, a nominal current of 24A, and a maximum load current of 31A with a 4 mm² conductor. The block has a slim 5.2 mm width and is constructed from polyamide (PA) insulating material with a UL 94 V0 flammability rating. Due to its robust design and compliance with various standards including fire protection for rail vehicles, it is well-suited for applications in the railway industry, machine building, and plant engineering.
