The C10H4TM016C is a 4-pole ComPacT NSX100H MCCB with a 16 A thermal-magnetic TM-D trip unit. At 240 V AC it delivers 100 kA Icu, so it handles high-fault service entrances without cascading upstream. The TM-D trip unit gives you fixed thermal (L) and magnetic (I) protection — no interchangeable rating plugs, no electronic adjustments. For a 16 A distribution feeder or a small motor branch circuit, that's a set-and-forget choice. The 4-pole version with neutral left and 1 x Ir neutral protection means the neutral is fully rated and switched, not just a solid link. Mounts on a backplate, not a DIN rail — the 140 mm width and 161 mm height take up a standard MCCB cutout in a panel. Front connections top and bottom simplify busbar or cable landing.
IP40 front-of-panel protection means it's fine in a general-purpose industrial enclosure; if the panel gets hosed down, you'll need a separate IP65 enclosure or a rotary handle kit that seals the front cutout. Electrical durability is 50,000 cycles at 440 V In/2 and 30,000 cycles at 440 V In — that's a lot of switching for an MCCB, reflecting the NSX design's robust mechanism. Mechanical durability is 50,000 cycles. If you're using this as a manual disconnect that gets cycled daily, those numbers give you a solid service life before contact wear becomes a concern.
