Product Description
It uses a TM-D thermal-magnetic trip unit with fixed overload and short-circuit settings, delivering 25 kA Icu at 220/240 V AC and 18 kA Icu at 380/400 V AC to IEC 60947-2. The 3-pole, 3D unit is rated 690 V insulation and 6 kV impulse withstand, with a 440 V AC working voltage. It is a fixed, panel-mounted device operated by a front handle and is designed for compact distribution boards and machine control panels. The Schneider Electric Osmart NSC160S is a 160 A frame molded case circuit breaker (MCCB) for low-voltage power distribution and final circuit protection.

Technical Specifications
Version & Model Difference
The NSC160S is the 160 A frame in the Osmart NSC range, offered as a 3-pole fixed breaker with a TM-D thermal-magnetic trip unit; other ratings in the same frame and 4-pole versions are configured differently. This is a molded case (MCCB) device, not a miniature or residual-current breaker, so verify pole count, rated current and trip unit before ordering.
Application Scenarios
- Main and sub-distribution boards in commercial and industrial buildings
- Machine control panels and motor feeder protection
- Protection of feeders to downstream distribution boards and large loads
