Information About HED43B050
The HED43B050 is part of the Siemens Sentron Series, engineered for dependable low-voltage power distribution in industrial and commercial installations. It features a compact ED-frame molded case design that supports mechanical durability and consistent electrical performance. The breaker integrates thermal and magnetic trip elements to provide stable protection under overload conditions and rapid response during short circuits. It is commonly installed in panelboards and distribution systems where bolt-on mounting and high interrupting capacity are required.
Key Features
- Three-pole circuit breaker configuration: Provides simultaneous protection and disconnection across all phases in three-phase electrical systems.
- 50 amp continuous current rating: Supports branch and feeder circuits with moderate load requirements while maintaining stable thermal performance.
- Thermal magnetic protection system: Uses a bimetal element for long-time overload protection and a magnetic mechanism for instantaneous short-circuit interruption.
- Long-time and instantaneous trip functions: Ensures selective protection for both sustained overcurrent conditions and sudden fault events.
- High interrupting capacity: Rated at 42 kA at 480 V, allowing safe interruption of high fault currents in demanding electrical environments.
- Bolt-on mounting design: Provides a secure and vibration-resistant connection to panel bus structures for long-term reliability.
- ED-frame molded case construction: Delivers a compact footprint with mechanical strength suitable for industrial panel applications.
- Load side lug terminals included: Simplifies field installation by supporting direct conductor termination without additional accessories.
The HED43B050 delivers the reliability and precision required for protecting three-phase electrical distribution circuits in industrial and commercial power systems.
