Phoenix 3100305 Feed-Through Terminal Block MT 1.5, Screw Connection, 1.5 mm², 500 V, 17.5 A, DIN Rail, Gray

Rated for 500 V and 17.5 A, the Phoenix 3100305 MT 1.5 feed-through terminal block delivers reliable screw-clamp connections for solid and flexible conductors up to 1.5 mm². Its compact 4.2 mm width saves space on the DIN rail while the V0-rated polyamide housing ensures fire safety in demanding industrial environments.

Overview

The Phoenix MT 1.5 is a single-level, single-position feed-through terminal block engineered for DIN rail mounting on NS 35/7.5 or NS 35/15 profiles. It provides two screw connections for secure wiring of conductors from 0.14 mm² to 1.5 mm² (26–16 AWG). The gray polyamide insulating body meets UL 94 V0 flammability standards, making it suitable for control cabinets, distribution boards, and automation systems.

What stands out

• High current rating of 17.5 A and 500 V rated voltage for versatile power distribution.
• Accepts both solid and flexible conductors up to 1.5 mm², with 8 mm stripping length.
• M2 screw thread with 0.22–0.25 Nm tightening torque for reliable, maintenance-free connections.
• Compact 4.2 mm width maximizes terminal density on standard DIN rails.
• Pollution degree 3 and overvoltage category III with 6 kV surge voltage rating for harsh electrical environments.
