Modular Contactor

Characteristics

AOCT series Household AC Contactor (also called modular AC Contactor), is mainly used in power systems with current 50Hz/60Hz, rated working voltage up to 400V, and rated working current up to 100A. Under the AC-1, AC-7a (No-inductive or low-inductive load, resistance furnace, household appliances or low-inductive load for similar purposes) usage category, it can be used as remote switch and control circuit, and also can be used to control household motor load. Household AC contactors are not used to break short-circuit current, so appropriate short-circuit protection appliances (such as Micro Circuit Breaker) should be selected when in use. Compliance with IEC61095, GB17885 standards.
AOCT Household AC Contactor has expandable auxiliary control, protection and indication functions. Mainly used in homes, hotels, apartments, office buildings, public buildings, shopping centers, stadiums and other places.

Product Technical Characteristics:

Quota work system:

a) Eight-hour work system: This is the basic operating system, and the agreed free air heating current lth of the contactor is determined by this operating system.

b) Intermittent work system: The rated operating frequency of Household AC Contactor under this working system is 30 times/h, and the load factor is 40%.

Action (operation) conditions:

When the ambient air temperature is within the range of -5℃~+40℃, the contactor attracting coil is applied with the quota control power supply voltage( Us ) to make it heat to a stable state, the contactor should be in the range of (85%~110%) Us can be closed reliably at any voltage; it is released and disconnected between 75% and 20% of the rated control power supply voltage(Us).

Product life:

Mechanical life: The mechanical life of the modular contactor is not less than 1 million times.

Electrical life: The electrical life of the modular contactor is not less than 100,000 times.


Normal working conditions:

Ambient air temperature: The upper limit of the ambient air temperature is +40℃, and the lower limit is -5℃. Whenthe contactor is installed in the distribution box, spacer must be assembled on both sides to facilitate heat dissipation.

Altitude: The altitude of the installation site must not exceed 2000 meters.

Atmospheric conditions:when the installation temperature is +40℃, the relative humidity in the air cannot exceed50%, and higher relative humidity can be allowed at lower temperatures, for example, the relative humidity of the air can reach 90% at +20℃. Special measures should be taken for condensation caused by temperature changes.

Pollution degree: ClassⅡ.

Installation category: ClassⅡ.

Installation method: Adopt TH35-7.5 guide rail installation, there is no obvious shock and vibration at the installation place, vertical installation, the inclination of the installation surface from any direction cannot exceed 5°.


Features:

①Modular control electrical appliances, novel structure, small size.

②The installation is track-based, modular size, safe use. It can be combined with a miniature circuit breaker and installed in the distribution box.

③The use of high-quality insulating materials, greatly enhance the safety.

④Nice appearance, with working status indicator window.

⑤No noise, suitable for hotels, hospitals and other places.


Working principle:

When the coil is energized, the coil current generates a magnetic field to generate enough electromagnetic attraction to attract the fixed core and make the contacts connected. When the coil voltage disappears or the coil voltage will drop to a certain value(release voltage), the electromagnetic attraction is weakened and driven by the reaction force spring, the fixed core drives the contacts to disconnect.
