Modular Design for Smart Identification

● Isolation function

● It can be assembled with accessories for remote signaling contacts

● Smart identification of lightning current and industrial frequency current

Ultimate Protection for Safe and Reliable

● MUH1 residual voltage at both ends of the surge is lower, and the corresponding MUH1 branch has a lower effective voltage protection level, thus the equipment can be better protected

● It adopts modular structure to assemble into a whole, with independent protection for each phase, flexible combination with SPD, and installation by 35mm standard rail

Flexible and High Performance

● Optional surge withstand capacity of 20kA (8/20μs), 40kA (8/20μs), 65kA (8/20μs), 80kA (8/20μs) 100kA (8/20μs), 120kA (8/20μs)

● The MUH1 protects SPDs from ToV damage, can cut off high short-circuit currents up to 100kA, and can cut off low short-circuit currents above 3A in a very short period of time
