Ensure proper mounting alignment with the contactor, correct wiring of control circuits, accurate overload dial setting based on motor FLC, and verify the trip/reset operation.
Check full-load motor current, trip class rating, compatibility with Siemens contactors, auxiliary contact requirements, and reset mode settings.
It monitors the motor current and trips during overload, phase failure, or overheating, preventing damage to motor windings and extending operational lifespan.
It is used in MCC panels, pump applications, conveyor systems, compressors, HVAC units, and industrial automation setups requiring overload protection.
The SIEMENS 3UA5800-2FZ1 is a high-grade Over Load Relay engineered primarily to protect three-phase AC electric motors from damaging thermal overloads, prolonged stalled rotors, and phase imbalances. As detailed in its technical specifications, this relay operates as a 3UA5 bimetallic thermal overload relay (highly dependable motor protection relay widely used in standard Indian motor starters, offering phase failure protection and manual/auto reset). It is an essential component for motor control centers (MCCs) and automation panels across India, and can be procured directly with full manufacturer warranty on Electrihub.
The SIEMENS 3UA5800-2FZ1 Over Load Relay utilizes internal bimetallic strips calibrated to bend under continuous overcurrent, heating up until they mechanically actuate the auxiliary trip contacts (95-96 NC and 97-98 NO). Additionally, it features differential tripping/travel mechanisms that provide accelerated tripping in the event of a single-phasing or phase failure condition. This prevents severe motor winding burnouts, making the 3UA5800-2FZ1 exceptionally reliable for unpredictable power grids in Indian industrial zones.
The SIEMENS 3UA5800-2FZ1 is structurally and electrically optimized for direct plug-in mounting to matching SIEMENS power contactors (such as the standard industrial starter ranges), creating a compact and rigid direct-on-line (DOL) or Star-Delta starter assembly. For standalone applications or independent panel mounting, it can be attached to an independent DIN rail or base plate adapter using standard screw terminals, ensuring flexible integration inside electrical panels sourced via Electrihub.in.
The SIEMENS 3UA5800-2FZ1 features a front-accessible, adjustable dial that allows panel engineers to precisely set the current trip threshold matching the motor's full load current (FLC). It also includes a versatile user-selectable reset button supporting both 'Manual' reset (requiring field maintenance intervention after a fault verification) and 'Automatic' reset modes. A mechanical trip indication indicator is integrated to speed up diagnostics during maintenance cycles.
Electrihub is India’s leading B2B e-commerce platform for authorized industrial switchgear and automation components. When purchasing the SIEMENS 3UA5800-2FZ1 Over Load Relay through Electrihub.in, buyers receive 100% genuine products, full compliance with GST tax invoicing, access to bulk commercial discount schemes, rapid logistics to major industrial hubs, and dedicated technical customer support for complex switchgear coordination challenges.
