Phoenix 3209604 PTTBS 2.5 dubbelverdieping-doorvoerklem, push-in aansluiting, grijs

Unlike standard single-level terminal blocks that consume more rail space and complicate wiring, the Phoenix 3209604 PTTBS 2.5 double-level terminal block doubles connection density in the same footprint. Its push-in connection technology allows solid or stranded conductors to be inserted directly without tools, dramatically reducing installation time. The grey polyamide housing is halogen-free and UL 94 V0 rated, ensuring safety in control cabinets and industrial distribution systems.

Highlights

• Two-level design with 4 push-in connection points for high-density wiring
• Tool-free push-in termination for solid and stranded conductors up to 2.5 mm²
• Rated for 500 V and 24 A (IEC), suitable for demanding industrial applications
• Mounts on standard DIN rail NS 35/7.5 or NS 35/15
• Wide operating temperature range from -60 °C to +105 °C
• Flammability rating UL 94 V0 and pollution degree 3 for harsh environments

In daily use

This double-level feed-through terminal block is ideal for control panels, machine building, and power distribution where space is limited. The push-in mechanism accepts conductors from 0.14 mm² to 4 mm² solid and 0.14 mm² to 2.5 mm² stranded (AWG 26–12). A stripping length of 8–10 mm ensures reliable contact. The grey PA housing resists chemicals and mechanical stress, while the 6 kV rated surge voltage and overvoltage category III provide robust protection against transients.
