The core function of the Fuji NP1BS-03 is to receive the mechanical action signals from the circuit breaker, and then use the internal push rod group to restrict external operations. It is usually equipped with high-brightness LED digital displays (the main display shows the measured value PV, the secondary display shows the set value SV or the output value MV), which remain clearly readable even in dimly lit industrial cabinets. If you are interested, please come to Tongtu. We have a wide range of model options.
This Fuji NP1BS-03 module does not have a circuit board. It transmits force through a precise mechanical structure. Its core is a high-strength force-transmitting rod. One end of this rod aligns with the main shaft cam inside the circuit breaker, and the other end is connected to a set of spring reset mechanisms. When the circuit breaker closes, the main shaft cam presses against the rod, and the rod overcomes the force of the springs to move, simultaneously driving the metal lock piece at the end to extend, thus completing the "locking" action. The internal slide rails and rotating shaft parts have been lubricated, with extremely low friction resistance. All the plastic force-bearing points are embedded with metal reinforcing ribs, which are definitely not just pure plastic contact, thus significantly extending its mechanical lifespan under frequent operations.
Last year, we had a European food processing plant customer. Their distribution cabinet was given a rectification notice due to failing the safety review. The reason was that the original mechanical interlock module's plastic had aged and broken, and the circuit breaker could still open the door when it was closed. They tried to assemble it with a different brand part on their own, but found that the size of the base slot was off by two millimeters, and it simply wouldn't fit. Later, they found in Yueyang Tongtu that they needed to order this Fuji NP1BS-03. Our technicians had already checked the circuit breaker's nameplate with them in advance. After the module was sent over, the electrician opened the circuit breaker panel, gently pushed it along the guide rail, and it was easily positioned. Then, they screwed it in and when they closed the circuit breaker, the lock piece steadily extended and locked the door frame. The inspection personnel passed the acceptance inspection on the spot. The customer later left a message saying that this original-sized part is reliable. It solved the major problem in just a few minutes.
In the same process, the quality of the Fuji NP1BS-03 provided is by no means a compromise. We solemnly guarantee that all products are 100% brand-new and original genuine products. From the very source, we completely eliminate any refurbished, second-hand or defective items. Our strength is not only reflected in the deep coverage of Fujitsu's entire series, but also extends to numerous international leading industrial control brands, covering thousands of different models, to meet the one-stop purchasing solution. Our products have been exported to many countries and regions around the world, precisely spanning different countries' industrial standards and individualized needs, and have won wide acclaim and solid trust from international customers on the global stage.
