SMBP-MZSR200JK1AR

The SMBP-MZSR200JK1AR is a smart surge protective device (SPD) with a built-in surge counter, designed for the primary side of a leakage breaker in single-phase two-wire systems. Compliant with IEC 61643-11 (Class II) and RoHS, it offers a maximum discharge current of 40 kA (8/20 µs), a nominal discharge current of 20 kA and a voltage protection level of 1.4 kV or less per phase (1.5 kV N-PE), with a maximum continuous operating voltage of 275 V AC. It measures and displays lightning surge current and count, shows a replacement recommendation, and includes a deterioration indicator with a warning contact output. Its plug-in, 35 mm DIN rail design simplifies installation and maintenance in switchboards, distribution boards and control equipment power circuits.
