Technical Specifications

Installation Guidelines

• Mounting: Designed for installation on 35 mm DIN rails conforming to EN 60715 with a secure locking mechanism.
• Side-by-Side Mounting: Utilizes a double slot and key connection system for rigid terminal block assembly.
• Wiring: Supports solid (s), stranded (st), and ferrule (f) conductors. Spring actuation is performed using a screwdriver.
• Connection Cross-sections:
  • Solid/Stranded: 0.08…2.5 mm² (AWG 28…14)
  • With Ferrule: 0.14…1.5 mm² (AWG 26…16)
• Stripping Length: 8…9 mm.
• Safety: Ensure proper grounding and verify that total load does not exceed the specified ∑ 10 A limit.
