RSP-CL-232
The Relpol RSP-CL-232 is surge protector for surge protection in IT and Bus data transmission systems. Application: in data and communication systems: 0-20 mA, 4-20 mA current loop, TTY 4-20 mA, TTY, TTL, V24 (RS232C). Rated operating voltage: 24 V DC. Maximum continuous operating voltage: 33 V DC / 23.3 V AC.
The protection capability of RSP-CL-232 is defined by the surge-current, operating-voltage, pole and class/type values stated above. Those exact ratings should be matched to the protected AC installation and its required lightning/surge protection level.
