Siemens LL14374-2 Three-Phase Circuit Breaker

The Siemens LL14374-2 is a specialized industrial circuit breaker built to handle continuous electrical loads rated at exactly fifty amperes across three separate poles for three-phase protection applications involving various motor feeds or resistive loads. Originally branded under ITE before acquisition, this model retains full compatibility with Siemens distribution centers and maintains established safety standards for commercial power systems used in diverse facility wiring configurations. Technicians utilize this device within main disconnect assemblies and motor control centers to interrupt dangerous fault currents automatically before damage spreads to downstream connected equipment. Constructed with durable materials suitable for tight interior panel clearance, the housing insulates live contacts effectively to prevent accidental contact during routine operation and maintenance procedures. Selecting this specific part number ensures that the replacement unit matches the physical footprint and electrical characteristics required for legacy hardware previously installed in the customer’s facility.
