Fuse link - NH2/K gG 315A/690V - time-lag / with striker 004114350

NH2 Fuse Links – Reliable Installation Protection

The NH2 fuse link with a rated current of 315A and a voltage of 690V is an element used to protect electrical circuits against overloads and short circuits. It is characterized by a time-delay gG characteristic, which means that it allows for short-term current overloads without disconnecting the circuit – an ideal solution for devices with high starting current. Additionally, the fuse link is equipped with a striker, which increases safety by quickly extinguishing the electric arc in the event of a failure.

Construction and application

NH2 fuse links are widely used in industrial installations, public buildings, and in electrical switchgear. They are used to protect circuits powering motors, transformers and other high-power devices. The time-delay characteristic (gG) makes them particularly useful where short-term current surges occur, for example when starting motors. The striker built into the construction provides additional safety and minimizes the risk of electric arc formation when the circuit is disconnected.

Key features and benefits

• High breaking capacity: Ensures effective protection of the installation against the effects of short circuits.
• Time-delay gG characteristic: Allows for short-term current overloads without unnecessary disconnection of the circuit, which is important for devices with high starting current.
• Rated voltage 690V: Enables use in a wide range of electrical installations.
• Rated current 315A: Suitable for protecting circuits with high power consumption.
• Striker: Increases safety by quickly extinguishing the electric arc.
• Compliance with standards: ETI fuse links meet the requirements of PN-93/E-06160 and PN-IEC-269 standards, which guarantees their reliability and safety.
• AC voltage type: Designed to operate in alternating current circuits.

It is important to remember that proper selection of the fuse link for a specific application is crucial to ensure effective protection of the electrical installation. The rated current of the circuit, the load characteristic and the regulatory requirements must be taken into account.
