Schneider Electric NSX250N TM250D Circuit Breaker

ComPacT NSX250N TM250D is a three‑pole, 250 A low‑voltage molded‑case circuit breaker from Schneider Electric, configured as a 3P3D unit with a TM250D thermal‑magnetic trip device. It is designed for panel‑mounted installation in 415 V AC systems and offers a short‑circuit breaking capacity of up to 50 kA at 415 V, with a nominal current range of 175–250 A. The compact NSX250N frame measures 105 x 161 x 86 mm (W x H x D), making it suitable for space‑constrained distribution panels. This device provides standard three‑phase protection for feeders in industrial or commercial power distribution applications, delivering reliable long‑time and instantaneous protection through the TM250D trip unit.
