MCZovp with three-stage overvoltage protection

Overvoltage protection in slim terminal housing (6mm) with PE contact and spring clamp connection in sizes 0.5 to 1.5mm². The PE connection is made by snapping onto an earthed 35mm mounting rail . The signal to PE using is protected using gas discharge tubes and varistors and between the lines using high-speed suppression diodes.


Applications include current loops 0(4) to 20mA and 0 to 10 V signals

Technical data

Rated voltage: 24V

Resistance per path: 2.5 ohms at 0.5A or 1 ohms at 1.25A
