PV FUSE NH3LgPV 1100V DC 315A-630A

PV FUSE NH3LgPV 1100V DC 315A-630A

Product catalog summary

Overview: This document provides technical specifications and details for photovoltaic fuses, specifically the NH2MgS and NH3LgPV models, designed for high voltage applications.

Standards: The fuses comply with IEC 60269-6 and GB/T 13539.6 standards.

Interrupting Capacity: The NH3LgPV model has an interrupting capacity of 50,000 A at 1100V DC with a time constant of 1-3ms.

Electrical Characteristics: The document outlines the conventional time and current ratings for the fuses. For currents between 160A and 400A, the conventional time is 3 hours, while for currents above 400A, it is 4 hours. The conventional non-fusing current is 1.13 times the rated current, and the conventional fusing current is 1.45 times the rated current.

Technical Parameters: The document lists part numbers, current ratings, and safety approvals. The fuses are available in various configurations, including blade contacts with indicators and bolted connections with optional microswitch bases.

Optional Accessories: Fuse holders and microswitches are available as optional accessories for the fuses.

Dimensions: The document provides dimensions in millimeters for the fuses.
