Phoenix 3044636 UTTB 2,5 Borne de série de dois andares

For installations where space is at a premium but connectivity demands remain high, the Phoenix 3044636 UTTB 2,5 double-level terminal block delivers two independent potential levels in a single compact housing. This design effectively doubles wiring density on the DIN rail without increasing footprint, making it a practical choice for control cabinets and distribution boards. The screw connection system ensures reliable, maintenance-free clamping for solid and flexible conductors up to 2.5 mm², while the gray polyamide insulation meets UL 94 V0 flammability requirements for enhanced safety.

Highlights

• Double-level design: two potentials in one block, saving rail space.
• Screw connection with M3 thread, torque 0.5–0.6 Nm for secure clamping.
• Wide conductor range: 0.14–4 mm² solid, 0.14–2.5 mm² flexible (AWG 26–12).
• Rated for 500 V / 24 A (IEC), pollution degree 3.
• Mounts on standard DIN rail NS 35/7.5 or NS 35/15.
• Insulating material: polyamide (PA), flammability rating UL 94 V0.

In daily use

Electricians appreciate the straightforward wiring: strip 9 mm of insulation, insert the conductor, and tighten the screw to the specified torque. The double-level arrangement keeps wiring organized and accessible, reducing troubleshooting time. The block's compact dimensions allow high-density packing, and the robust PA housing withstands mechanical stress and thermal loads typical in industrial environments.
