The Schneider Electric C10F4TM032 is a ComPacT NSX100F circuit breaker with a 32 A thermal-magnetic TM-D trip unit, 4 poles, and an F breaking capacity code — meaning 36 kA Icu at 380/415 V AC. It's rated 85 kA Icu at 220/240 V AC and still delivers 22 kA Icu at 525 V AC, so it covers both light commercial and heavy industrial distribution panels without swapping frames. The TM-D trip unit gives you L (thermal overload) and I (magnetic short-circuit) protection, with the neutral protection set at 1 x Ir for a 4D configuration. That means the breaker tracks overload on all four poles equally — no derating guesswork when you land a balanced 3-phase plus neutral feed. Mechanical durability is rated at 50,000 cycles, with electrical durability ranging from 50,000 cycles at 440 V In/2 down to 10,000 cycles at 690 V In. For a panel that sees regular switching — like a pump start/stop or a conveyor section — that's a solid service life before you're pulling a replacement.
The 140 mm width and 161 mm height give it a footprint that matches standard ComPacT NSX panel cutouts, and the 35 mm connection pitch lines up with common busbar systems and terminal blocks. Front connections on both the line and load sides mean you can bus it in a panel without flipping the breaker or adding awkward right-angle adapters. The toggle control is right there on the front — no pushbutton or rotary handle to confuse a maintenance crew pulling a lockout.
Environmental and compliance specs that matter for the install
IP40 enclosure protection keeps dust and fingers out, and the IK07 impact rating means it'll survive a tool bump in a crowded panel. Operating altitude goes to 2000 m without derating, and up to 5000 m with derating — worth checking if your site sits above a mile high. Compliant with EN/IEC 60947-2 and suitable for isolation per that standard, so it doubles as a visible-break disconnect when the toggle is in the OFF position. No separate isolator needed on the load side for most code jurisdictions.
