The Schneider Electric PowerPacT H-Series HSM2-400 is a high-performance molded case circuit breaker (MCCB) from the PowerPacT H-Series range, specifically designed for mounting in motor starters (e.g., TeSys island).
Parameters:
Parameter Value / Description
Product Line / Series PowerPacT H-Series (for Motor Protection)
Product Type Motor Circuit Protector (MCP / MPCB) - HSM2
Frame Size (Iu) 400 A
Rated Current (In) Adjustable via interchangeable thermal/magnetic trip units or fixed. Must be selected to match the motor's Full Load Amps (FLA) and starting characteristics.
Number of Poles Typically 3 (for three-phase motor circuits).
Breaking Capacity High. Specific Icu value depends on the voltage (e.g., 65 kA Icu at 480V AC is common for this series).
Rated Operational Voltage (Ue) Typically up to 690 V AC.
Motor Protection Features • Magnetic-Only Trip (Instantaneous): Provides short-circuit and locked rotor protection. The trip threshold is set based on motor starting current (typically 13x FLA).
• No Thermal Overload Protection: This is a key distinction. It does NOT provide overload protection. A separate overload relay (e.g., TeSys LRD/LRE) is mandatory to complete the motor protection scheme.
Trip Unit Type Adjustable magnetic trip unit (for setting the instantaneous pickup) or fixed.
Standard IEC/EN 60947-2 (as a circuit-breaker) and relevant parts of IEC/EN 60947-4-1 (for motor starter applications).
Mounting & Integration Designed for direct mounting onto TeSys Island motor starter bases or other compatible mounting systems. This allows for compact, pre-wired, modular motor starter assemblies.
Connection Integrated connection for busbar or cable, designed for easy connection to contactor and overload relay within the starter assembly.
Function Primary: Short-circuit protection and a manual disconnect/isolation point for the motor circuit.
