Installation switch module I-0-II common point from above 3P 40A 400VAC SFT340

Installation switch for demanding applications

This Hager SFT340 modular installation switch is a reliable solution for switching power in electrical circuits. Designed for mounting on a TH35 rail, it allows convenient and safe control of a load with a current of up to 40A at a voltage of 400V AC. The design with a common point from above (I-0-II) allows for flexible circuit management, offering the possibility of selecting one of two power sources or completely disconnecting the circuit.

Functionality and application

The SFT340 switch finds application in both home and industrial installations. It is ideal for anywhere where reliable circuit switching is required, e.g. in electrical switchboards, lighting control systems or workshops. The three-pole design (3P) provides full protection and control over the circuit. The staircase switch function allows control of lighting from two different locations.

Solid construction and safety

Made of high-quality materials, the SFT340 switch guarantees long-lasting and trouble-free operation. The IP20 degree of protection protects against accidental contact and the ingress of solid objects larger than 12.5 mm. The rated switching capacity of 0.846 kA ensures effective protection of the installation against the effects of short circuits. Mechanical endurance of 200,000 cycles confirms the high durability of the device. The switch meets the standards PN/EN 60669-1 and PN/EN 60943-3, which guarantees its safety and compliance with applicable regulations. The width of the device, 3 modules, facilitates mounting in standard switchboards.
