Fuse link - NH2C gG 50A/500V - time-lag 004185231

Reliable installation protection with NH2C gG 50A/500V fuse link

This knife fuse link, catalog number 004185231, is a key element in protecting electrical installations from the effects of short circuits and overloads. Designed for industrial applications, it meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. Its solid construction and precise electrical parameters guarantee reliable operation in demanding conditions.

Construction and characteristic features

The fuse link is made of high-quality steatite, a material that provides thermal stability. The silver-plated knife contacts are made of brass, minimizing resistance and ensuring efficient current flow. Aluminum covers protect against corrosion, and the tightly sand-filled quartz sand body with a special granulation increases the short-circuit breaking capacity and stabilizes the electrical parameters. It is worth noting the dual tripping indicator - a red eye on the ceramic body and a springy plate on the top cover - which facilitates quick identification of a blown fuse. This system provides very good visibility of the fuse status in both fuse bases and fuse disconnectors.

Application and benefits for installers and users

The NH2C gG 50A/500V fuse link is primarily used to protect cables and equipment with time-current characteristics corresponding to the old delayed-action (gG) fuse links. Its rated current is 50A at 500V AC, and its short-circuit breaking capacity reaches as much as 120kA. This ensures effective protection against damage caused by overloads or short circuits. The dual tripping indicator facilitates diagnostics and quick replacement of a damaged fuse, minimizing installation downtime. Additionally, the ability to cooperate with the NVS 5 microswitch enables remote signaling of tripping, which is particularly important in monitoring and automation systems. The value of the total Joule integral of switching is 25000 A²s, and the pre-arcing 3000 A²s, which proves the high energy efficiency of the device.

• For installers: easy installation thanks to silver-plated knife contacts and the possibility of remote tripping signaling.
• For users: high reliability and effective protection of the electrical installation, minimizing the risk of failures and downtime.
• Production in the EU: guarantee of quality and compliance with European standards.
• Versatility: can be used with various types of fuse bases and fuse disconnectors.
