Terminal block Simet 15‑pole neutral connector N, for TS35 DIN rail, 15×16 mm², model 870N/15 (blue)

Simet 15‑pole neutral connector 870N/15 (blue) is a compact DIN‑rail terminal block designed for neutral distribution in electrical panels. It mounts on standard TS35 rails and provides fifteen identical poles for connecting neutral conductors. Each pole accepts conductors up to 16 mm², allowing secure clamping and electrical continuity while keeping neutral wiring clearly identifiable by the blue insulation. The product is intended for use in distribution boards, control cabinets and other indoor electrical installations that require organized multi‑pole neutral termination.

Advantages

The terminal block offers consistent mechanical and electrical performance across all fifteen poles, with a space‑saving profile compatible with TS35 mounting. Blue insulation simplifies identification of the neutral bus, reducing wiring errors during installation and maintenance. The design supports conductors up to 16 mm², providing flexibility for a range of cross‑sections used in industrial and building installations. Durable materials ensure long‑term electrical isolation and resistance to typical panel environments.

Suitable for

• Neutral distribution in electrical switchboards and distribution panels
• Control cabinet wiring for machines and automation equipment
• Building electrical installations requiring multiple neutral terminations
• Panel layouts where clear color coding for neutral conductors is required

Key specifications

• Number of poles: 15
• Conductor capacity per pole: up to 16 mm²
• Mounting: TS35 DIN rail
• Function: neutral (N) connector
• Color: blue (neutral identification)

How to use

Mount the terminal block on a TS35 DIN rail by snapping it into place or using the recommended DIN‑rail fastening method. Prepare conductor ends to the appropriate length and strip insulation according to conductor size. Insert each neutral conductor into the corresponding pole and tighten the clamping mechanism to the torque recommended for conductors of that cross‑section. Ensure all connections are secure and that the terminal block is positioned to maintain clear identification of neutral wiring within the panel.

Usage recommendations

Use the blue terminal block exclusively for neutral conductors to maintain standard color coding. Verify conductor cross‑section compatibility and apply the proper tightening torque to avoid loose connections. Inspect connections periodically as part of panel maintenance and follow applicable electrical standards and safety procedures during installation.
