Product Overview

The TB345-05SP is a dual-row terminal block from EATON, where "SP" denotes Steel SEMS phil-slot, zinc-plated screws. With 5 poles, 600V/45A rating, it enhances installation convenience and vibration resistance through screw design, ideal for industrial wiring in high-vibration or frequent-maintenance scenarios.

Key Features

• SEMS Screw Design：Zinc-plated steel SEMS screws integrate spring washer function, eliminating the need for extra anti-loosening parts and improving installation efficiency by 30%.
• Vibration Resistance：Passes 10G vibration test (50~2000Hz) with self-locking screws, reducing loosening risks in machinery applications.
• Tool-Free Installation：Phillips-head screws fit standard drivers, enabling single-handed operation in tight spaces.
• Corrosion Protection：Zinc plating (≥5μm) withstands 96-hour salt spray test, suitable for humid environments.
• Accessory Compatibility：Works with TB345 series jumpers (e.g., OJ6) and marking strips, minimizing inventory costs.
