Class H Fuses

Bussmann NOS Series fuses, also known as supplemental one-time fuses are used to protect equipment from overcurrent situations. Unlike traditional fuses, they cannot be reset or reused once they have opened (blown) and are intended to be replaced after each use. These Class H fuses are sensitive to temporary current surges, making them ideal for light-duty circuit locations. They are available in knife blade / clip type termination variants and are designed to deliver an interrupting rating of up to 50kA at 600VAC.

Bussmann Class K5 fuses protect lighting, heating and other circuits from rapid changes in electrical current. They are designed to interrupt overcurrents at normal operating currents and moderate fault currents. These NOS Series fuses feature a melamine body to protect outer components.

Bussmann NOS Series Class H fuses are ideal for high inrush current environments, such as motor circuits, transformers and power distribution systems. These Class H fuse units feature a balance between overload & short-circuit protection, ensuring the uninterrupted functioning of essential machinery. They have melamine body construction for enhanced durability, heat resistance and insulating properties. These Class H fuses have an AC voltage rating of 600VAC to protect high-voltage electrical systems.
