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
