Procurement Intelligence
The OS20TPN series is a compact enclosed wall-mount isolator switch rated for 20A maximum current in 3-phase + neutral (3+N) configurations. It serves as a manual disconnection device for low-voltage circuit protection and control in residential, commercial, and light industrial installations. Critical verification: confirm voltage rating (typically 230/400V) and compliance with local electrical standards (IEC 60947-3) before procurement.
Three-phase low-voltage disconnection
Before ordering — verify:
| ☐ | Voltage rating confirmation |
| ☐ | Wall space availability |
| ☐ | Cable entry method |
