Product Overview

The TB345-05B is an upgraded dual-row terminal block from EATON, enhancing anti-static performance and mounting compatibility over TB345-05. With 5 poles, 600V/45A rating, and #10-32 screw connections, its 0.562" (14mm) pitch suits high-current wiring in industrial automation and power distribution, especially for ESD-sensitive equipment.

Key Features

• Enhanced ESD Protection：Base coated with ≤10⁹Ω anti-static layer, reducing electromagnetic interference in precision circuits.
• High Current Handling：45A continuous rating (55A peak) supports 8-22 AWG wires, with 8 AWG torque increased to 28 in-lbs for 15% lower contact resistance.
• Wide Temperature Resistance：Operates -40°C~130°C, passes IP65 splash test for outdoor vibration environments.
• Quick Marking System：Includes L6 dual-color marking strips, compatible with thermal transfer labeling.
• Universal Rail Compatibility：Fits 35mm DIN-Rail and C-Rail (NFTA/NRA) via snap-on brackets, improving installation flexibility.

Technical Specifications

Typical Applications

• High-Frequency Communications：Reduces signal crosstalk in 5G base station power units.
• Renewable Energy Systems：Supports -25°C cold start and 120°C continuous operation in PV inverters.
• Robotic Production Lines：Passes 1000-cycle vibration test (50Hz~2000Hz) for dynamic stability.
• Medical Power Supplies：Complies with UL 60601-1, insulation resistance ≥100MΩ@500V DC.
• Aerospace Ground Equipment：Salt spray resistance (5% NaCl, 96h) with ≤5% contact resistance change.

Why Choose TB345-05B?

• Triple Protection：ESD + splash + vibration resistance for harsh environments.
• Thermal Optimization：5μm silver plating reduces temperature rise to ≤30K@45A.
• Accessory Compatibility：Works with all TB345 series parts, OJ6-B jumpers support live 插拔.
• Expanded Certifications：New VDE 0660-101 approval for European high-end equipment.
• Eco-Friendly：Lead-free process, compliant with RoHS 2.0 and REACH SVHC 211.
