Technical Questions Answered

Q: Why choose non-fused over fused blocks?

A: Non-fused blocks provide cleaner signal paths when external protection exists or when fuse resistance might affect measurement accuracy.

Q: What does 20 mΩ contact resistance mean for signals?

A: This extremely low resistance minimizes voltage drop, crucial for accurate voltage and low-current analog measurements.

Q: How does 100 MΩ insulation help analog signals?

A: High insulation prevents leakage currents that can create measurement errors in sensitive analog circuits.

Q: What's the benefit of 5.08mm terminal pitch?

A: Standard spacing accommodates common wire sizes and allows proper clearances for safe operation at 300V.

Q: When should I use this block?

A: Ideal for precision measurement applications where signal integrity outweighs the need for individual point fusing.
