Modular isolating switch 4P 25A 400VAC SBN425

Modular isolating switch – reliable disconnection in your installation

This four-pole isolating switch from Hager, with a rated current of 25A and a voltage of 400VAC, is a key element ensuring safety and control in electrical circuits. SBN425 is used in both domestic and industrial installations, allowing effective disconnection of loads from the power supply. Its compact design (2 module widths) facilitates mounting in distribution boards.

Functionality and technical parameters

The SBN425 switch is characterized by high reliability and durability. The rated switching capacity of 0.529 kA and the short-circuit strength (Icw) of 0.375 kA guarantee protection against the effects of overloads and short circuits. The IP20 degree of protection provides basic protection against touch and ingress of solid objects. The device has 4 switching contacts, allowing for complete isolation of the circuit. Designed to operate at a frequency of 50-60Hz, it meets the requirements of modern electrical installations.

Installation and application – for professionals and users

The switch is easy and intuitive to install thanks to the use of screw terminals, accepting rigid conductors with a cross-section of 1.5 - 16 mm² and flexible conductors 1.5 - 10 mm². This solution facilitates the work of installers and also allows for easy replacement if servicing the installation is necessary. The switch is used wherever safe and reliable disconnection of the circuit is required – during equipment maintenance, repairs or electrical installation modernization. Its versatility makes it ideal for both new and existing installations.
