Phoenix Contact 3036042 ST 2,5-3L Multi-level terminal block 20A

The Phoenix Contact ST 2,5-3L is a 3-level spring-cage terminal block rated at 500 V and 20 A, combining two separate circuits in a single 5.2 mm wide DIN rail unit. Conductors from 0.08 mm² to 4 mm² are accepted across all three levels, with no cross-section restriction when using ferrule-terminated conductors.
