About This Product

■Features

1.SPD external separator (MCCB) and SPD are integrated, minimizing wiring inside the panel Integration of the SPD external separator eliminates external wiring between the SPD and separator, significantly reducing wiring man-hours. Optimal lightning protection is achieved by keeping the wiring as short as possible. 2.Simply plug it into the main busbar to complete the connection Integrate the busbar direct connection insertion mount and insert it into the busbar unit to complete the connection. It is possible to downsize, standardize, and shorten the production period of switchboards and distribution boards. *Must be fixed with the included screws (tightening torque: 4.7 to 5.2N・m) 3. Equipped with an inspection disconnect function that allows inspection while the main breaker is energized. Molded case circuit breaker (MCCB): When replacing or inspecting the SPD unit, the circuit breaker is operated to open the circuit, allowing work to be performed without voltage. 4. Great protection ability Voltage protection level is below 1,300V, impulse current Iimp25kA, protects facilities and equipment from damage caused by direct lightning strikes. 5.Only the SPD part can be replaced 6. Comes with a safety function even when it deteriorates ・Two-stage protection function (SPD internal automatic disconnection device operates, SPD external separator trips) ・With SPD function display ・Supports degraded contact output (LD-B22E3S-P only) 7. Compatible with RoHS regulated substances
