Pollmann N 14-S liitettävä nollajohtimen liitinrima sininen

In distribution boards and control cabinets, electricians often need a reliable way to distribute the neutral conductor to multiple outgoing circuits. The Pollmann N 14-S pluggable neutral conductor terminal block solves this with a single main input and 14 auxiliary outputs, all in a compact, fully insulated blue housing. Its push-in connection technology makes wiring fast and tool-free for solid conductors, while still accommodating flexible conductors with ferrules.

Key specifications

• Main conductor cross-section: 1.5 – 16 mm² (rigid/flexible)
• Auxiliary conductor cross-section: 14 x 1.5 – 4 mm² (rigid/flexible)
• Total connection points: 15 (1 main + 14 auxiliary)
• Nominal voltage: 400 V
• Nominal current: 63 A
• Connection type: Pluggable (push-in)
• Colour: Blue
• Mounting: Screw mounting
• Housing material: Polyamide (PA)
• Contact material: Brass, nickel-plated
• Stripping length: 12 mm (for 1.5–4 mm²)
• Operating temperature: -25 °C to +80 °C
• Protection class: IP20 (when installed)

Why choose it

The push-in terminals reduce installation time significantly compared to screw terminals, and the pluggable design allows for quick disconnection during testing or maintenance. The blue colour clearly identifies the neutral conductor per common wiring standards, enhancing safety and compliance. Its robust polyamide housing and nickel-plated brass contacts ensure long-term reliability in demanding electrical environments.

Ideal use cases

• Distribution of neutral conductors in residential and commercial distribution boards
• Control cabinet wiring where multiple neutral connections are required
• Retrofit and maintenance work where quick disconnection is beneficial

Good to know

The terminal block is fully insulated and rated IP20 when installed, providing protection against solid objects larger than 12 mm. It supports both solid and stranded conductors, making it versatile for various wiring practices. The blue colour is standard for neutral conductors in many regions, aiding in quick identification and reducing wiring errors.
