MERSEN FUSE NH 2 355A 500V AM NH2AM50V355

Why Choose the Mersen NH2AM50V355 NH Fuse Link?

The Mersen NH2AM50V355 is a robust DIN NH aM fuse link developed for short-circuit protection in high-current motor circuits and industrial electrical installations. With its partial-range aM operating characteristic, this fuse link provides effective protection against severe fault currents while allowing the temporary inrush currents associated with motor starting.

Part of Mersen's NH aM 500 V AC fuse-link range, the NH2AM50V355 combines strong current-limiting performance with low power losses. It features a durable ceramic body, blade contacts, non-insulated live gripping lugs and a double indication system that helps maintenance personnel identify an operated fuse quickly.

With a rated current of 355 A, a rated voltage of 500 V AC and an NH2 format, this fuse link is suitable for large motors, motor control centres and heavy industrial machinery. As an aM fuse, it provides short-circuit protection and must be coordinated with a suitable overload protection device.

Key Advantages

• Industrial-grade DIN NH Size 2 aM fuse link.
• 355 A rated current for high-power motor circuits.
• 500 V AC rating for industrial low-voltage systems.
• Strong current-limiting action helps reduce damage during short circuits.
• Double indication system supports rapid fault identification.
• Live gripping lugs support removal using a suitable NH fuse handle.

Reliable Short-Circuit Protection for Motor Circuits

Type aM fuse links are partial-range devices designed specifically for motor circuit protection. Their operating characteristics allow normal motor starting currents to pass while providing rapid interruption of high fault currents that could otherwise damage cables, contactors, starters and motor windings.

The NH2AM50V355 must be used with suitable overload protection because an aM fuse does not provide full-range overload protection. When correctly coordinated with a motor protection relay, circuit breaker or starter, it forms part of a dependable protection system for high-power industrial motors.

Typical Applications

• High-power industrial motor circuits.
• Motor control centres and starter assemblies.
• Pumps, compressors and ventilation systems.
• Conveyors and material handling machinery.
• Manufacturing and processing equipment.
• Industrial switchboards and control panels.
