Technical Overview

Protective earth terminal block with spring-cage connection for 0.2-10mm² (AWG 24-8) conductors. Rated 1000V/600V, operates -60°C to 110°C.

Key Features

  • Spring-cage connection provides vibration-resistant, gas-tight, and stable connections.
  • Accommodates conductors from 0.2 mm² to 10 mm² (AWG 24-8).
  • Features low logistics costs due to compatibility with uniform CLIPLINE complete accessories.
  • Offers a comprehensive range of accessories for bridging, testing, and marking.
  • Tested and suitable for railway applications.
  • Ensures low contact resistance and corrosion-free terminal points.
  • Green-yellow housing clearly identifies it as a protective conductor terminal block.
  • Designed for standard DIN rail mounting (NS 35/7.5, NS 35/15).
  • Operates reliably in a wide temperature range from -60 °C to 110 °C.

The maintenance-free spring-cage connection ensures proven vibration resistance, gas-tight, and long-term stable conductor contacting, eliminating the need for periodic retightening in critical applications.

Industrial Applications

1. Grounding in High-Vibration Industrial Machinery

This terminal block is an ideal solution for establishing reliable protective earth connections in industrial machinery that experiences constant and intense vibrations, such as large motors, stamping presses, or heavy-duty conveyor systems. The robust spring-cage connection ensures secure, gas-tight, and vibration-resistant contacts.

Problem Solved

Prevents unreliable grounding caused by the loosening of traditional screw connections in high-vibration environments, which can lead to equipment malfunction, intermittent faults, or critical safety hazards. Its maintenance-free design significantly reduces the need for periodic inspection and retightening, minimizing operational downtime.

3. Hazardous Area Grounding in Chemical and Petrochemical Plants

Given its designation for use in Ex zones, its Insulating Material Group I classification, and UL 94 V0 flammability rating, this protective conductor terminal block is excellent for safely grounding electrical equipment within potentially explosive atmospheres found in chemical, petrochemical, or pharmaceutical processing plants.

Problem Solved

Ensures safe and compliant protective earthing within hazardous (Ex) areas, effectively minimizing the risk of ignition sources from static discharge or electrical faults. This is crucial for preventing explosions and ensuring operational safety in environments containing flammable gases, vapors, or combustible dusts.
