CHINT NHRT41 Fuse-switch Disconnector is a robust horizontal fuse-switch solution engineered for demanding low-voltage distribution applications. Featuring advanced arc-protection and dual mounting flexibility, it provides reliable load switching and overcurrent protection for critical infrastructure including substations and feeder pillars.

1. Product Overview

The NHRT41 series is designed for AC 50Hz/60Hz circuits in low-voltage distribution systems. It combines manual load switching capabilities with integrated fuse protection, making it ideal for substations, feeder pillars, and control panels where safe circuit isolation and overcurrent protection are essential. Available in standard (NHRT41-3) and linked-operation (NHRT41-3L) configurations.

2. Main Features

Arc-protected Busbar Shielding: Enhanced safety with integrated arc protection for busbar systems
Fuse Replacement Interlock: Safety mechanism prevents operation during fuse replacement
Voltage Inspection Holes: Allows safe circuit verification without live part contact
Dual Mounting Design: Flexible bolt-fixing or hook-fixing options for easy panel integration
High-grade Materials: Fiberglass-reinforced unsaturated polyester body with silver-coated contacts
Model Variants: NHRT41-3 (independent phase) and NHRT41-3L (three-phase simultaneous operation)

3. Technical and Application Notes

The NHRT41 features a horizontal design optimized for panel mounting. The silver-coated contacts ensure minimal temperature rise and superior conductivity during long-term operation. Installation can be performed using either bolt-fixing for permanent mounting or hook-fixing for quick installation on existing busbar systems without additional modifications. The “L” variant (NHRT41-3L) enables three-phase simultaneous operation, while the standard model allows independent phase control.

4. Typical Applications

Electrical Substations: Primary switching and protection for distribution transformers
Feeder Pillars: Load switching and protection for outdoor distribution networks
Control Panels: Motor control and protection in industrial automation systems
Power Distribution Centers: Main incoming and outgoing circuit protection
Infrastructure Projects: Reliable switching for critical public utilities

5. Ordering Support

Please specify the model variant (NHRT41-3 for independent phase operation or NHRT41-3L for three-phase simultaneous operation), rated current, and mounting preference when ordering. We provide technical consultation for selecting the appropriate configuration for your specific panel or busbar system requirements.
