It features a switched neutral configuration, making it suitable for applications requiring neutral switching in addition to hot-leg interruption. At one inch wide per pole, the compact form factor fits standard bolt-on bus configurations in both residential and commercial electrical panels. The quick-make and quick-break mechanism provides consistent, reliable operation, while the built-in trip indication allows technicians to identify a tripped breaker at a glance.\u003c\/p\u003e\n\u003cp\u003eThis breaker is used in residential load centers and commercial lighting panels where bolt-on breaker mounting is required. The switched neutral design is appropriate for specific branch circuit applications such as multi-wire branch circuits or installations governed by local code requiring neutral switching. It can also be ordered with auxiliary contact and shunt trip accessories for control or monitoring integration, and is available in configurations for HID lighting applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBolt-on design for secure bus connection in load centers and lighting panels\u003c\/li\u003e\n  \u003cli\u003eSwitched neutral configuration provides simultaneous neutral and hot-leg switching\u003c\/li\u003e\n  \u003cli\u003eThermal-magnetic trip mechanism protects against overload and short-circuit conditions\u003c\/li\u003e\n  \u003cli\u003eQuick-make and quick-break action ensures reliable, consistent switching performance\u003c\/li\u003e\n  \u003cli\u003eEasy-to-spot trip indication for fast visual fault identification\u003c\/li\u003e\n  \u003cli\u003eCompatible with auxiliary contact and shunt trip accessories for expanded functionality\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style bolt-on replacement for 2-pole Q Line breaker positions in residential and commercial load centers and lighting panels that accept bolt-on breaker configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the panel and verify the absence of voltage before handling or installing the breaker. Ensure the bolt-on bus connections are properly seated and torqued to the panel manufacturer specifications. Switched neutral breakers must be wired to interrupt both the hot and neutral conductors simultaneously as required by the application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoles\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Thermal-Magnetic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Bolt-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeutral Configuration\u003c\/strong\u003e: Switched Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Per Pole\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 783164103557\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ABB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: THQB21WY20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383709466930,"sku":"THQB21WY20","price":415.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312672462.png?v=1782605095","url":"https:\/\/voomisupply.com\/products\/abb-thqb21wy20-bolt-on-circuit-breaker-2p-20a","provider":"Voomi Supply","version":"1.0","type":"link"}
