As a Class RK5 fuse, it is specifically engineered to handle the temporary high-current surges typical of motor starts and transformer inrush, while still providing rapid response to sustained overloads or short circuits. This time-delay feature is essential for preventing nuisance blowing in systems where inductive loads are present. With a high interrupting rating of 200,000 Amps, the ECSR12 provides a robust safety barrier that protects sensitive equipment and personnel from the catastrophic effects of electrical faults. Its dual-element construction ensures consistent performance and energy-efficient operation across its entire service life.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-Element Design:\u003c\/strong\u003e Provides a 10-second time delay at 500% of the rated load to accommodate motor starting surges.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Limiting:\u003c\/strong\u003e Effectively reduces the magnitude of peak fault currents to protect downstream system components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Safety Rating:\u003c\/strong\u003e Features a massive 200kA interrupting rating to safely handle high-energy electrical faults.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile Application:\u003c\/strong\u003e Suitable for branch circuit protection, motor control centers, and HVAC disconnects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass RK5 Protection:\u003c\/strong\u003e Meets stringent UL standards for safety and reliability in critical power distribution systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Bussmann\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e ECSR12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 12 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 600V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass:\u003c\/strong\u003e RK5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 200,000 AIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Time-Delay \/ Dual-Element\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eDirect replacement models\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eBussmann FRS-R-12, Mersen TRS12R, Littelfuse FLSR012, Edison ECSR12.\u003c\/p\u003e\u003cp\u003eYou will receive the same product or an OEM-Equivalent that meets the highest standard of the OEM with warranty that will be a direct-fit.
