Small Breaker, Big Protector: JCB3LM-80′s Smart Specs
This compact circuit breaker balances strong protection and easy installation, with rated currents up to 80A, high breaking capacity, and versatile terminals for cables and busbars.
Ever wondered how your electrical system stays safe during a sudden overload or fault? Meet the JCB3LM-80—a clever little device that’s big on protection! This miniature circuit breaker might look humble, but it’s packed with smart engineering to keep things running smoothly and safely.
Let’s start with its rated current. Ranging from 6A to 80A, this breaker can handle everything from lighting circuits to heavier appliances. Whether it’s your cozy home setup or a more demanding commercial environment, there’s a version tailored just for the job.
Then there’s its type: electromagnetic and available in both AC and A wave sensitivity. That means it detects not only standard alternating current leaks but also pulsating DC ones—making it extra versatile in modern settings where devices like inverters and dimmers are common.
But what really stands out is its rated breaking capacity of 6KA. In simple terms, if something goes seriously wrong—like a short circuit—this breaker can interrupt up to 6000 amps of current almost instantly. Think of it as an emergency stop button for electricity!
Installation is where it gets even friendlier. The terminal size accepts cables up to 25mm² and busbars up to 10mm². That’s plenty of room for secure connections, whether you’re using standard wiring or more rigid busbars. And don’t forget the tightening torque—2.5 N·m. This might sound technical, but it’s just the right amount of “hug” for the wires: tight enough to stay secure, but not so tight that anything gets damaged.
So next time you flip a switch or plug in a device, remember there’s a tiny guardian like the JCB3LM-80 working behind the scenes—making sure everything stays safe, sound, and seriously efficient!
