NOVARIS SIGNAL LINE PROTECTOR 1 PAIR 10kA SL420-G

Product Code: SL420-G

The Signal Line Protector is designed to provide maximum protection for various industrial equipment. With a maximum continuous operating voltage of 34VDC, it ensures reliable performance. It can handle a maximum discharge current of 5kA per line (10kA common mode) at 8/20ms and a maximum impulse current of 1.25kA per line (2.5kA common mode) at 10/350ms. This protector also offers a maximum load current of 30mA and voltage protection levels of <40V (L-L) and <350V (L-PE) at 1kV/ms. Its connection type is series, and it features a replacement top module with G Base, which allows for easy installation on DIN rails. The Signal Line Protector is ideal for protecting PLCs, fire and security systems, telecommunications and telemetry systems, railway signaling, SCADA, and other industrial monitoring and control equipment. It is designed for DIN rail mounting and has an IP20 rating for added durability.
