Distribution block PAWBOL E.4090/SZ 160A 1P terminal sizes 2x2.5–50/4x2.5–16/3x2.5–25

PAWBOL E.4090/SZ 160A 1P distribution block is a single-pole terminal block designed to provide reliable high-current connections for electrical panels and control cabinets. It accommodates conductors of different cross-sections in dedicated terminal groups—2×2.5–50 mm², 4×2.5–16 mm² and 3×2.5–25 mm²—allowing flexible incoming and outgoing wiring while maintaining a compact footprint. The product is intended for organized power distribution where a single-phase, high-current common point is required.

Advantages

The distribution block offers a clear separation of conductor groups for easy wiring and maintenance, reducing installation time. Its rated current of 160 A supports high-load circuits, and the multi-size terminals accommodate a wide range of conductor cross-sections without the need for additional adapters. The single-pole design simplifies busbar or supply distribution to multiple outputs while preserving electrical continuity and mechanical stability.

Suitable for

• Electrical distribution panels and switchboards
• Industrial control cabinets and automation panels
• Power supply splitting for single-phase circuits
• Connection points in machinery and equipment requiring organized high-current terminals

Key specifications

• Rated current: 160 A
• Poles: 1 (single-pole)
• Terminal capacities: groups for 2×2.5–50 mm², 4×2.5–16 mm² and 3×2.5–25 mm² conductors
• Mounting: panel or DIN-rail compatible form factor (check panel layout for fit)
• Material: insulated housing with metal conductive terminals for secure clamping

How to use

Mount the distribution block in the electrical panel or cabinet ensuring it is accessible for wiring and inspection. Select the appropriate terminal group for each conductor according to its cross-section and strip the conductor to the correct length. Insert conductors fully into the designated terminals and tighten the clamping screws to the manufacturer’s recommended torque to ensure secure electrical contact. Verify continuity and tightenings before energizing the circuit.

Usage recommendations

Use the distribution block within its rated current and temperature limits. Where necessary, combine with correctly sized ferrules or sleeves for stranded conductors to improve contact reliability. Ensure wire sizes match the specified terminal ranges and avoid exceeding the maximum conductor cross-section for each terminal group. Regularly inspect connections for mechanical tightness and signs of overheating in high-load applications.
