What is the function of the Okken Low Voltage Switchgear secondary connector?

The secondary connector (usually called secondary connector or control circuit plug) of Schneider

Electric OKKEN series 0.4kV low-voltage switchgear is the core component of its modular design

and plays a key role in system integration and operation and maintenance.

OKKEN secondary connectors materials meet the requirements of industrial durability and

electrical performance:

Conductor part Pins: Phosphor bronze gold-plated (thickness ≥ 0.5 μ m), reduce contact

resistance (<5mΩ), anti-oxidation.

Terminal crimping piece: Brass tin-plated, supports more than 500 plug-in and pull-out lifespan.

Insulation Cover

Base: Flame-retardant engineering plastic PA66+30% glass fiber (UL94 V-0 grade), temperature

resistant to 120°C.

Shell: Nickel-plated aluminum alloy (IP40 protection) or reinforced nylon (IP20), impact-resistant

and corrosion-resistant.

With silicone rubber sealing ring to meet IP54 protection (plugged status), with dust and

moisture proof.

OKKEN special design features:

Anti-misinsertion structure

Key slot positioning + color coding (such as communication port is blue) to avoid wrong insertion.

Self-locking mechanism

Screw-type lock design, will not loosen in a vibrating environment.

Hot plug support
