Schneider Electric C16H3MA150 ComPacT NSX160H Motor Protection Circuit Breaker – 150 A, 3P3D, 70 kA @ 415 V AC, MA Trip Unit

Description du produit

The Schneider Electric C16H3MA150 is a complete 3-pole molded case circuit breaker from the ComPacT NSX160H range, specifically configured for motor protection applications. It is rated 150 A continuous current with a 3P3D (3 poles, 3 protected) configuration and delivers an ultimate breaking capacity (Icu) of 70 kA at 415 V AC, with a maximum operational voltage of 690 V AC. The breaker is equipped with an MA (Magnetic only) trip unit featuring an adjustable instantaneous short-circuit release range of 1350–2100 A, allowing precise coordination with motor starting characteristics when overload protection is provided separately by a thermal relay. The device is designed as a fixed built-in unit with screw connections for the main circuit and operates reliably from −25 °C to +70 °C with IP40 protection. Its compact dimensions of 105 mm × 161 mm × 86 mm optimize panel space, making it an optimal choice for motor feeders in industrial control and distribution systems.
