Modular contactor SM 340 40A 24V 2NO with actuator 412515

Universal modular contactor for various applications

This modular contactor, with a rated current of 40A and a control voltage of 24V AC, is a reliable solution for controlling electrical circuits in residential and commercial buildings. Equipped with two normally open contacts (2NO), it allows for efficient switching of loads such as lighting, heating, or pumps. The actuator allows manual adjustment of the contacts, which is particularly useful during servicing or testing of the installation.

Construction and functionality for professionals

The contactor is designed for mounting on a TH35 rail, occupying only 2 modules in width. Compliance with IEC/EN 61095 standard guarantees safety and reliability. Thanks to the possibility of additional equipment, it can be easily adapted to specific installation requirements. The IP2X degree of protection provides basic protection against touch and ingress of solid objects. The design with a slider for manual operation facilitates diagnostics and allows manual switching of the circuit if necessary.

Application and benefits for the end user

The SM 340 contactor is a versatile device that can be used in many areas:

• Lighting: Controlling lighting in residential, office, or commercial premises.
• Heating: Switching on and off electric heaters or underfloor heating systems.
• Pumps: Controlling circulating pumps in central heating or swimming pool systems.
• Other loads: Possibility of controlling various other electrical devices with a power of up to 5000W for incandescent lamps and 3100 VA for fluorescent lamps.

Thanks to its high switching capacity, the contactor ensures safe and efficient operation of connected devices. The actuator makes it easy to operate the device even without disconnecting the power supply – three positions of the actuator: "ON", "OFF" and "AUTO" (coil control of the contactor) give full control over the circuit.
