Fuse link - NH1/85 gG 200A/1000V - time-lag 004113717

Safety and protection of electrical installations

NH1/85 gG 200A/1000V fuse link is an element used to protect electrical circuits against overload and short circuit. Its function is to quickly disconnect the power supply in the event of a dangerous condition, minimizing the risk of damage to equipment and fire. This particular fuse link, with a rated current of 200A, is designed to operate in installations with a voltage of up to 1000V AC.

Time-delay characteristic and application

The fuse link has a gG (time-delay) characteristic, which means it allows for short-term exceeding of the rated current without tripping. This is particularly important for devices with motors or other loads generating high inrush currents. This avoids unnecessary switching off of the circuit during normal operation of the devices. The top indicator facilitates visual control of the fuse link status – whether it has operated and needs to be replaced.

Mounting and compatibility

NH1/85 fuse links are designed to work with appropriate fuse bases. It is important to select a base with an appropriate current and voltage class, in accordance with safety standards. The lack of metal insulated grips (IMGL) means that the fuse link does not have additional contact insulation, which should be taken into account when designing the installation. It is worth noting the high short-circuit breaking capacity of 120kA, which ensures effective protection even in the event of serious short circuits.
