3-pole power disconnector 1600A BG4 N4-1600 266028

Universal solution for large installations

The 3-pole power disconnector with a rated current of 1600 A is a key component of any industrial switchboard operating in networks up to 690 V. Thanks to its robust construction and lever-operated switching mechanism, it enables quick and safe disconnection of power even under high inrush currents. The locking mechanism ensures secure closure of the lever in the OFF position – ideal for both installers requiring reliable mounting and end-users valuing system reliability.

Key features and benefits

• High short-time withstand current of 25 kA – protects the circuit against the effects of short circuits and allows safe disconnection of motors with high starting torque.
• Three poles and stud connection – simple installation in busbar systems without the need for additional adapters.
• Locking mechanism and provision for padlocking – prevents accidental switching, enhancing operational safety.
• Optional motor operator and undervoltage release – enable automation and remote control in SCADA or BMS systems.
• IP20 protection class (front) – provides protection against dust and accidental contact with control elements.
• Compliance with standards IEC/EN 60204, IEC/EN 60947‑3, and VDE 0113/0660 – meets safety and quality requirements applicable in Europe.
• Fixed mounting construction – designed for installation in distribution boards and as an intermediate component in larger systems.

Applications and compatibility

The disconnector is suitable as a main switch in industrial installations, in emergency power supply systems, and as a service device enabling quick disconnection of components during maintenance. Thanks to its capability to function as an emergency disconnector (NOT‑AUS) and a service disconnector, it is ideal for:

• low-voltage switchboards in manufacturing plants,
• photovoltaic systems and energy storage installations,
• heat pump installations and electric drives requiring high inrush currents,
• projects requiring integration with remote operators or undervoltage releases.

The product is intended for permanent installation in distribution boards (not for front mounting) and can be used both in new installations and during the modernization of existing power networks.
