Striebel & John Set de equipamiento para unidad de conexión de contador con protección contra sobretensiones, 250 A, 1 campo, tipo 1+2

The Striebel & John Equipment Set for Meter Connection Unit (ZAE+f.OVR ZP) is a comprehensive solution designed for modern metering points requiring integrated overvoltage protection. This set combines a 1-field meter connection unit with a Type 1+2 combined arrester, ensuring reliable protection against lightning and switching surges. Ideal for TN-S and TT systems, it meets stringent safety standards and simplifies installation in meter cabinets.

Advantages

Integrated overvoltage protection saves space and reduces installation time. The Type 1+2 arrester handles high-energy surges (Iimp 7 kA, In 20 kA) and provides low protection level (<1.5 kV). Rated for 250 A, it supports high-demand residential and commercial applications. Complies with DIN VDE 0100-443, DIN VDE 0100-534, and DIN EN 61643-11.

Suitable for

• Meter cabinets in residential buildings
• Commercial metering points
• TN-S and TT earthing systems
• New installations or retrofits requiring surge protection
