It's a current-production part — no lifecycle concerns for new BOM lines or spares restocking. DC rating on the 60947-2 side is 15 kA at 60 V. That IEC 60947-2 / UL 1077 dual-rating is what lets you drop this into a UL 508A industrial control panel without a separate series fuse for SCCR compliance, as long as the available fault current stays under the 5 kA UL 1077 mark.
Depth behind the panel is 70 mm installation depth; overall depth 76 mm. Combined top and bottom terminals let you loop feed-through without extra links — saves a terminal block row in dense layouts. Sealable for lockout/tagout compliance. Halogen-free and silicon-free construction matters in clean-room or semiconductor fab zones where outgassing contaminates optics or wafers.
Ambient temperature range -40 to 75 °C with humidity derating: max 95% RH at 55 °C, tapering to 35% at 75 °C. Rated for 50/60 Hz AC supply. Operating voltage AC 400 V, with multi-phase and single-phase operation up to 440 V. DC operating voltage max 72 V.
