Product Overview
The TB345-05ST is a dual-row terminal block from EATON, where "ST" denotes Stainless Steel screws. With 5 poles, 600V/45A rating, it enhances corrosion and heat resistance through material upgrade, ideal for chemical, marine, and high-temperature industrial wiring.
Key Features
- 304 Stainless Steel Screws：#10-32 304 SS screws withstand 720-hour salt spray test (5% NaCl), 3x more corrosion-resistant than zinc-plated steel.
- High-Temperature Tolerance：Nickel-plated screw terminals support 150°C continuous operation, +20°C compared to TB345-05.
- Vibration Resistance：Optimized thread design passes 8G vibration test (50~2000Hz), reducing loosening risks.
- Universal Mounting：Compatible with 35mm DIN-Rail (DRL35MMHI/L) and C-Rail (NFTA/NRA), same installation as TB345-05.
- Easy Maintenance：Smooth SS surface resists fouling, cleanable with solvents for sanitary applications.

+ —1. Do TB345-05ST screws need anti-loosening? >
- SS screws have natural self-locking; spring washers (optional) for severe vibration.
-
+ —2. Suitable for -40°C cold storage? >
- Yes, base remains flexible, contact resistance change ≤5% in cold chain setups.
-
+ —3. Why higher torque for SS screws? >
- Higher friction coefficient requires more torque; over-tightening may strip threads.
-
+ —4. Difference from TB345-05SP? >
- ST uses SS screws for corrosion/heat; SP has zinc SEMS screws (with spring washers) for faster installation.
