Featuring an adjustable full-load current (FLC) range of 1.0 to 2.9 A, a fixed Class 10 trip curve, and manual reset functionality, it connects directly to Allen-Bradley Bulletin 100-A and 104-A contactors (sizes A09 through A30).\u003c\/p\u003e\n\u003ch3\u003eSolid-State Thermal Modeling \u0026amp; Protection Features\u003c\/h3\u003e\n\u003cp\u003eThe module utilizes an application-specific integrated circuit (ASIC) to model motor thermal characteristics accurately using true RMS current measurement. In contrast to traditional bimetallic relays, the solid-state design consumes approximately 150 mW of power, significantly reducing heat dissipation inside control enclosures while delivering built-in phase-loss protection that trips within 2 seconds under single-phasing conditions.\u003c\/p\u003e\n\u003ch3\u003eContactor Compatibility \u0026amp; Mounting Architecture\u003c\/h3\u003e\n\u003cp\u003eDesigned for direct plug-in mounting without external jumper wires or secondary mounting hardware, the module physically attaches to Bulletin 100-A and 104-A IEC contactor frames. Main power conductors feed directly into screw-type line terminals, while integrated auxiliary contacts support local and remote alarm indication loops.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e193-A1D1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eSolid-State Overload Relays\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Line\u003c\/td\u003e\n\u003ctd\u003eBulletin 193 (SMP-1 Series)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Adjustment Range\u003c\/td\u003e\n\u003ctd\u003e1.0 - 2.9 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTrip Class\u003c\/td\u003e\n\u003ctd\u003eClass 10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReset Mode\u003c\/td\u003e\n\u003ctd\u003eManual Reset\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContactor Compatibility\u003c\/td\u003e\n\u003ctd\u003eBulletin 100-A \/ 104-A (A09 to A30)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInternal Power Consumption\u003c\/td\u003e\n\u003ctd\u003e~150 mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-25 deg C to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.40 lbs (0.18 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eBefore mounting, ensure the contactor load terminals are fully opened to accept the relay's connection pins.

A: The solid-state electronic modeling lowers power consumption to roughly 150 mW and provides rapid 2-second phase-loss protection to protect motor windings during single-phasing events.\u003c\/p\u003e\n\u003cp\u003eQ: Can the reset mode on the 193-A1D1 be converted to automatic reset? A: No, the 193-A1D1 features a dedicated manual reset mechanism. Automated reset functionality requires a Bulletin 193-A4 catalog variant (such as the 193-A4D1).\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":67092269760627,"sku":"193-A1D1","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/193-A1D1_Cocoai_8b80310e-9f88-49a2-93a2-961b9ddc4855.jpg?v=1793609553","url":"https:\/\/www.dcssupplier.com\/ar\/products\/allen-bradley-193-a1d1-solid-state-overload-relay","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
