Hello, I am currently working on the Mitsubishi MR-J5-70A amplifier and I am seeking guidance on determining the appropriate fuse size. The main power requirement is a single-phase 240VAC with a rated current of 6.5A, while the controller power requires a single-phase 250VAC with a rated current of 0.2A. Can I use a 6.5A fuse for the main power and a 0.2A fuse for the controller power, or is there a specific calculation method for selecting the correct fuses? Thank you.
When it comes to drives or servo amplifiers, it is advisable to adhere closely to the circuit protection guidelines provided in the manual. It is essential to consider inrush current, as the rated power usage may not cover it. Using the recommended breakers or fuses by the manufacturer gives you a written reference point in case of failure or tripping, ensuring your decision is well-documented and scrutinized.
Hi there, great question! In the electrical world, fuses are typically selected to be 1.5 to 2 times the nominal current, offering a buffer to prevent nuisance tripping due to minor fluctuations. For your main power with 6.5A, I'd recommend a 10A fuse. Similarly, for your controller, a 0.3A to 0.4A fuse would be suitable. Remember, the role of the fuse is to protect your hardware from overcurrent, so a margin of safety is always preferable. Always refer to official recommendations from Mitsubishi for your specific model, but I hope this gives you a good starting point!
