With Part Number BGL36045, this unit integrates into Schneider Electric panels and distribution boards, delivering precise, synchronized disconnect across all phases when faults occur. While the model name includes “Potential Transformer,” its core role is robust overcurrent protection in systems that may also utilize protective relays and metering arrangements in three-phase networks.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWhat makes the BGL36045 stand out\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003e45 A continuous rating:\u003c\/strong\u003e targeted protection for medium-to-heavy feeders and motors without nuisance tripping.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003e3-pole configuration:\u003c\/strong\u003e guarantees simultaneous isolation of all three phases, reducing arcing risk and unbalance during fault conditions.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003e347 V voltage rating:\u003c\/strong\u003e suitable for common commercial and many industrial three-phase mains, providing safe operation and clear fault isolation at expected voltages.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eThermal-magnetic trip behavior:\u003c\/strong\u003e fast response to overloads and short circuits, helping to prevent equipment damage and downtime.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eDesigned for Schneider Electric ecosystems:\u003c\/strong\u003e easy replacement or upgrade within existing BGL-series panels and compatible enclosures, ensuring consistent performance and streamlined maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eIdeal use cases\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eThree-phase feeders in commercial buildings, manufacturing floors, and data-center auxiliary power rooms.\u003c\/li\u003e \u003cli\u003eMotor control circuits and pump banks where coordinated phase protection reduces equipment wear and unexpected shutdowns.\u003c\/li\u003e \u003cli\u003ePanelboard upgrades or replacements where a reliable, standard-compatible 3-pole breaker is required.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy operators choose this model\u003c\/h3\u003e\n\u003cp\u003eFor engineers and maintenance teams, the BGL36045 offers predictable protection in a compact, field-friendly package.
