For applications specifying Class H, Mersen NRS20 supplies the 20A rating in the NRS Series. Mersen publishes 600V AC for this rating, together with 10kA AC interrupting capability. The design focuses on standard non-time-delay protection for 600V AC general-purpose 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. Check the official Mersen datasheet before final equipment coordination.
