Eti-Polam KOMBI NH1 Fuse Link 200A aM 690V

The Eti-Polam KOMBI NH1 fuse link is a robust industrial electrical protection device engineered for high-performance power distribution systems. With a rated current of 200A and an aM characteristic, this fuse is specifically optimized to provide reliable protection for motor circuits, effectively handling the high inrush currents associated with motor startups while ensuring safety during short-circuit events. Designed for operation in 690V networks, this NH-1 size component is built to meet the rigorous demands of professional electrical installations, offering long-term durability and consistent performance.

Advantages

This fuse link stands out due to its specialized aM characteristic, which allows it to withstand temporary overcurrents typical of motor operations without nuisance tripping. The inclusion of a dual-indicator system provides immediate visual confirmation of the fuse status, significantly simplifying maintenance and troubleshooting processes in complex electrical panels. Its construction is focused on safety and reliability, ensuring that industrial equipment remains protected against electrical faults while maintaining operational continuity.

Suitable for

• Motor circuit protection in industrial environments
• Power distribution networks operating at 690V
• Electrical panels requiring NH-1 size fuse links
• Applications where high short-circuit breaking capacity is essential

When it may not be suitable

This fuse is not intended for general-purpose protection where a gG characteristic is required, as the aM characteristic is specifically designed for motor circuits and may not provide adequate overload protection for non-motor loads. It is also not suitable for systems exceeding the rated voltage of 690V.

Key specifications

• Rated current: 200A
• Characteristic: aM (motor protection)
• Rated voltage: 690V
• Size: NH-1
• Indicator type: Dual-indicator system

How to use

The fuse link should be installed into a compatible NH-1 fuse base or disconnect switch by a qualified professional. Ensure that the power supply is disconnected before installation to prevent electrical hazards. Align the fuse blades with the contact clips of the base and press firmly until it is securely seated. Regularly inspect the dual-indicator window to verify the operational status of the fuse.

What to consider before purchase

• Verify that the fuse size NH-1 matches your existing fuse base
• Ensure the 200A rating is appropriate for the motor load
• Confirm that the aM characteristic is suitable for your specific circuit requirements
• Check that the system voltage does not exceed 690V

Usage recommendations

Always use appropriate personal protective equipment when handling electrical components and ensure that the installation is performed in accordance with local electrical safety regulations.
