Modular installation switch I-0-II common point from above 1P 32A 230VAC SFT132

Hager SFT132 modular installation switch is a component used for convenient and safe control of lighting or other electrical devices in building installations. Its modular design allows for easy connection with other home automation elements. This switch is particularly useful in circuits requiring frequent switching, e.g., in stair lighting systems, where a stairwell switch function is crucial.

Functionality and application

This single-pole (1P) switch with a rated current of 32A and a voltage of 230VAC is perfect for standard electrical installations. Its main function is to act as a stairwell switch – allowing control of a single circuit from two different locations. The common point at the top facilitates connection to an existing installation, and the compact dimensions (1 module width, 70mm installation depth) allow for mounting even in limited space within the distribution board. The rated switching capacity of 0.677 kA ensures safety and reliable operation in the event of a short circuit.

Safety and technical parameters

The SFT132 switch is designed with user safety in mind. The IP20 degree of protection prevents accidental contact, but does not provide protection against moisture – therefore, the switch should be installed in dry rooms. Short-circuit strength at 0.48 kA demonstrates its resistance to overloads and short circuits in the installation. The lack of a signaling lamp minimizes power consumption and potential interference in the circuit. The minimum rated voltage of 230V guarantees correct operation under standard network conditions. The design without normally open and normally closed contacts, but only with one switching contact, simplifies the connection diagram and increases the reliability of operation.
