Risk: Insulation breakdown and electric shock accident
대안: HV series 1000V / 1500V high-voltage terminal blocks
- Unmatched wire gauge
– Wires thinner than 0.2 mm² → Use PT 2.5 시리즈
– Wires thicker than 6 mm² → Use PT 6 시리즈
- Mismatched Mechanical & Connection Conditions
- Frequent plugging over 100 타임스
Risk: Spring fatigue leading to loose contact
대안: Screw-type terminals or dedicated pluggable terminals
- No DIN rail installation condition
대안: Panel-mounted or fixed-type terminal blocks
- Multi-branch wiring requirement
Basic model only supports 2-wire straight connection; choose PT 4-QUATTRO for 4-wire connection
- Unsuitable Environmental Conditions
- Severe corrosive atmosphere
- Working temperature below -60℃ or above +110℃
- Excessive vibration and shock beyond industrial standard range
- Unmatched Functional Requirements
- Need built-in fuse protection, LED status indication or surge protection
- Higher explosion-proof grade than II 2 G Ex eb IIC Gb
- Ultra-high density wiring with width less than 6.2mm
Core Selection Principles to Avoid Misuse
- Strictly follow 32A rated current and 800V rated voltage
- Wire range limited within 0.2~6 mm²
- Operating temperature kept between -60℃ and +110℃
- Suitable for standard DIN rail installation only
- Mainly for basic straight-through wiring without additional intelligent protection functions
