Combining overcurrent protection and switch functions into one unit reduces the number of components. A design that blends well with the equipment. This product is suitable for circuit protection in applications.
The "Switch-Compatible Circuit Protector 3120 Series" eliminates the need for components such as switches, harnesses, fuse holders, and fuses, reducing the number of parts to achieve lower costs and compact size. It does not require fuse replacement, minimizing downtime. When an overcurrent occurs, the circuit breaker function activates, and the rocker switch automatically turns OFF. By removing the abnormal load and turning the rocker switch ON again, it can be reused. Its design harmonizes with various devices and equipment, making it suitable for a wide range of applications. 【Features and Specifications】 ■ Complies with international safety standards for medical electrical equipment (EN60601-1) ■ Also meets UL1077, CSA, VDE, and CQC standards ■ Suitable for a wide range of applications including machine tools, scientific instruments, construction machinery, vehicles, and motors ■ Dimensions: D25×W48×H52mm ■ Products with modules such as auxiliary circuit modules are also available Additionally, we offer: The "3130 Series" with 1-pole to 3-pole options, The fuse holder type "1110 Series," and The "3140 Series" with 3-pole and 4-pole options available in IP66 specifications.
