ABB Electrical DP40C3P-1/B/CE Definite Purpose Contactor

ABB Electrical DP40C3P-1/B/CE Definite Purpose Contactor

Basic Parameters

Rated current: 40A, can meet the control needs of medium power electrical equipment, such as some small to medium-sized motor.

Number of poles: 3 poles, suitable for three-phase circuit control, can simultaneously control the three-phase load on and off, commonly used in three-phase motor control circuit.

Control voltage: 120V AC, this voltage is the working voltage of the control coil, need to provide a stable 120V AC power supply to drive the contactor action.

Rated voltage: 600V, the maximum voltage that the main contacts can withstand, to ensure that the contactor can work safely and reliably in the circuit of the corresponding voltage level, can be applied to a variety of different voltage levels of the electrical system, but the access to the circuit voltage can not exceed this rated voltage.

Performance characteristics

High reliability: the contacts are made of high-quality materials and advanced manufacturing process, with good electrical conductivity, wear resistance and anti-melting welding, which can maintain stable contact performance under frequent on/off operation, reduce contact resistance, reduce energy consumption and heat generation, improve reliability and service life, and ensure stable operation of the electrical system.

Fast response: low inductance and resistance of the control coil can quickly generate electromagnetic force after connecting the control voltage, which makes the movable iron core quickly suction, driving the main contact to close, and realises fast connection to the load; when the control voltage is disconnected, it can also be quickly released, and cuts off the load circuit in time, which is suitable for occasions with high requirements on the speed of control.

Compact design: compact structure, small size, occupies less space, easy to install and wiring in a variety of electrical control cabinets, distribution boxes and other limited space, can save installation space, reduce the overall size and cost of the equipment, but also convenient to combine and integrate with other electrical components.

Good compatibility: As a member of ABB electrical product series, it has good compatibility and working ability with other ABB electrical components, such as overload relay, thermal relay, control relay, etc. It can form various control circuits and protection circuits, providing users with one-stop electrical solutions and reducing the complexity of system design and installation.

Conformity to standards: Conformity to a number of international standards, such as IEC 60947-4-1, UL 508, etc., to ensure that the products in the global scope of universality and reliability, can be in different countries and regions of the safe and stable operation of the electrical system, to meet the needs of a variety of industrial and commercial applications.

Application Areas

HVAC system: In the heating, ventilation and air conditioning system, it is used to control the start and stop of the motors of air conditioning units, chillers, fans and other equipment to achieve the regulation of indoor temperature, humidity and air circulation.

Food service equipment: can be used to control the motor in food processing equipment, such as ovens, freezers, mixers, etc., to ensure the normal operation of the equipment to meet the different needs of food processing.

Refrigeration equipment: commonly used to control motors in refrigeration equipment such as refrigeration compressors, condensing fans, evaporating fans, etc., to ensure the normal operation of the refrigeration system and to maintain a refrigerated and frozen environment.

Welding equipment: In welding equipment, it can control the operation of welding transformers, wire feeding motors, etc., to achieve precise control of the welding process, to ensure the quality of welding and the safe operation of the equipment.
