class h Mersen non-time-delay NRN Series NRN300

The Mersen NRN300 combines a 300A rating with the protection characteristics of the NRN Series. Mersen publishes 250V AC for this rating, together with 10kA AC interrupting capability. 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 Resistive Loads, Control Panels, General-Purpose Circuits. Use the official Mersen datasheet to confirm final coordination and dimensions.
