Mersen NRN40 40A 250V Class H Non-Time-Delay Fuse

For applications specifying Class H, Mersen NRN40 supplies the 40A rating in the NRN Series. For coordination, the key ratings are 250V AC and 10kA AC interrupting performance. Its circuit-protection behavior is defined by standard non-time-delay protection for general-purpose AC circuits. The Class H format uses ferrule / blade (amp-dependent) terminals with cartridge/clip mounting. Typical selection contexts include Lighting Circuits, Resistive Loads, Control Panels. Use the official Mersen datasheet to confirm final coordination and dimensions.
