Modular contactor SM 363 63A 230V 4NO silent 412563

Modular contactor – reliable control of electrical circuits

This modular contactor, with a rated current of 63A and a control voltage of 230V AC, is a key element in electrical installations requiring frequent load switching. It will work well in both residential and commercial buildings. Its compact size – only 3 modules wide – makes it easy to mount in distribution boards.

Functionality and application

The SM 363 contactor is designed for maneuvering connections, allowing remote control of lighting, heating or motor circuits. It has 4 normally open (NO) contacts, providing flexibility in circuit configuration. Additionally, the presence of a manual override slider allows for manual switching of the contacts during service work or installation testing – a useful solution for installers. Quiet operation minimizes noise during operation, which is important in residential premises.

Parameters and safety

The device is characterized by a high switching capacity:

• Incandescent bulbs: up to 8000 W
• Fluorescent lamps: up to 4700 VA (without compensation), 5000 VA (DUO compensation), 1700 VA (parallel compensation)

The rated operating voltage is 400 V AC, and the IP2X degree of protection provides basic protection against contact and ingress of solid objects. The contactor complies with IEC/EN 61095 standard, which guarantees its safety and reliability. The possibility of additional equipment allows it to be adapted to specific installation needs. The control voltage is in the range of 195 to 253 V AC. Mounting is done on a standard TH35 support.
