Modular contactor SM 340 40A 230V 2NO with actuator 412545

Modular contactor for a wide range of applications

This modular contactor SM 340 with a current of 40A and a voltage of 230V AC is a reliable solution for controlling various electrical loads. Thanks to two normally open contacts (2NO), it is ideal for installations requiring switching on and off of loads such as heating, lighting or pumps. The built-in actuator allows manual control, which is particularly useful during testing, maintenance or in emergency situations.

Construction and functionality

The contactor is designed for mounting on a standard TH35 rail, taking up only 2 modules in width. This compact design saves space in the distribution board. The rated operating voltage is 250V AC, and the operating current is 40A, ensuring safe and efficient operation with various types of loads. The contactor complies with IEC/EN 61095 standard, which guarantees its quality and safety. The IP2X protection degree protects against touching live parts and against the ingress of solid objects larger than 12.5 mm.

Switching capacity and additional features

The SM 340 contactor is characterized by high switching capacities:

• Incandescent bulbs: up to 5000 W
• Fluorescent lamps: up to 3100 VA (without compensation), up to 3400 VA (with DUO compensation) and up to 1400 VA (with parallel compensation).
• Expandability: The contactor offers the possibility of connecting additional equipment, which increases its functionality and flexibility.
• Control voltage: The control voltage range is 195-253V AC.
• Manual slider: Allows convenient manual switching on and off of the circuit without the need for external control.

Thanks to this, this contactor is a versatile solution for both professional installers and end users looking for a reliable element to control loads in their electrical installations.
