That means steadier trip performance and fewer nuisance trips caused by mechanical looseness or vibration in busy electrical panels.\u003c\/p\u003e \u003cp\u003eEquipped with a \u003cstrong\u003ethermal-magnetic trip unit\u003c\/strong\u003e, the THQB1140 provides stable, repeatable protection across a wide range of operating conditions. The thermal element responds to sustained overloads, while the magnetic element handles instantaneous short-circuit events, delivering fast, predictable disconnection to safeguard wiring and connected equipment.\u003c\/p\u003e \u003cp\u003eThe THQB1140 is \u003cstrong\u003ecompatible with matching OEM load centers and panelboards\u003c\/strong\u003e, ensuring a clean, plug-in replacement path within the same electrical system. This makes it a practical choice for upgrades, service replacements, or new installations that use bolt-on breakers in standard 1-pole configurations.\u003c\/p\u003e \u003cp\u003eIdeal for \u003cstrong\u003eresidential, commercial, and light industrial applications\u003c\/strong\u003e, this breaker protects individual branch circuits—from lighting and outlets to small equipment feeders—while fitting neatly into standard bolt-on installations. Its 1-pole design is well-suited for dedicated circuits where simple, reliable disconnection is required, and its 120V rating aligns with typical consumer and light commercial electrical systems.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eGuaranteed performance in panel environments\u003c\/strong\u003e thanks to bolt-on mounting that minimizes connection movement and arcing risk under vibration.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePrecise protection\u003c\/strong\u003e through a thermal-magnetic trip unit that responds predictably to overloads and short circuits.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSeamless integration\u003c\/strong\u003e with OEM load centers and panelboards designed for bolt-on breakers.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVersatile use cases\u003c\/strong\u003e across residential, commercial, and light industrial settings, providing targeted protection for individual circuits.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eTechnical snapshot\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eManufacturer: GE\u003c\/li\u003e \u003cli\u003ePart Number: THQB1140\u003c\/li\u003e \u003cli\u003eType: Thermal-magnetic molded case circuit breaker\u003c\/li\u003e \u003cli\u003eAmperage Rating: 40A\u003c\/li\u003e \u003cli\u003eVoltage Rating: 120V\u003c\/li\u003e \u003cli\u003eNumber of Poles: 1\u003c\/li\u003e \u003cli\u003eMounting Style: Bolt-on\u003c\/li\u003e \u003cli\u003eApplication: Branch circuit overcurrent and short-circuit protection\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhether you’re upgrading an aging panel, replacing a failed breaker, or stocking a spare for upcoming service work, the GE THQB1140 delivers dependable protection with installation simplicity.
