Modular isolating switch 3P 32A 400V SBN332

Isolating switch – safety and reliability in your installation

This three-pole Hager FR series isolating switch with a rated current of 32A is a key element of any electrical installation, providing effective protection and the ability to safely disconnect circuits. It is ideal for both domestic and industrial installations where high reliability and safety are required. The device's design allows for quick and easy disconnection of power in the event of a failure or the need to perform maintenance work.

Functionality and application

The SBN332 switch is designed to disconnect all types of current circuits, offering both current conduction under normal operating conditions and effective isolation in emergency situations. Its applications include:

• Main emergency disconnectors: Allows for quick power cut-off in the event of a hazard or the need for maintenance.
• Electrical distribution boards: Forms an integral part of distribution boards, providing safe disconnection of individual circuits.
• Industrial installations: Provides reliable disconnection of power to machines and equipment.
• Domestic installations: Protects against overload and short circuit, increasing safety of use.

Technical specifications and construction

The switch is characterized by a solid construction and high quality workmanship. Mounting on a 35 mm DIN rail (TH35) ensures easy and quick mounting in the distribution board. Screw terminals allow for secure and safe connection of wires with a cross-section of up to 16 mm² (solid wire) or 10 mm² (stranded wire). The device has a protection degree of IP20, which provides protection against accidental contact. Electrical endurance at 2500 cycles and mechanical endurance at 20000 cycles guarantee long-term and trouble-free operation. The rated switching capacity is 0.677 kA, and the short-circuit strength (Icw) is 0.48 kA – these parameters demonstrate its effectiveness in overload and short-circuit conditions. The width of the device is only 2 modules, which allows for optimal use of space in the distribution board. The rated voltage is 400V, and the minimum rated voltage is also 400V. The mounting depth is 68 mm.
