DC Magnetic Contactor

A KRIPAL DC Magnetic Contactor is an electromechanical switch designed specifically for Direct Current (DC) power circuits. It uses a DC control coil that, when energized, creates a magnetic field. This field moves a set of contacts to either close (completing the circuit) or open (breaking the circuit), allowing for remote control of high-power DC loads with a low-power signal.

KRIPAL DC Contactors offer a wide range of options to fit various applications:

• Coil Voltages: Standard options include DC 24V, 48V, 120V, 220V, and 250V.
• Current Ratings: The main contacts are robust, with a rated current range, making them suitable for both light control duties and heavy-power switching.

KRIPAL DC Contactors are versatile and reliable components used across multiple industries:

Industrial Automation: Ideal for start/stop control of small motors, pumps, and blowers on automated production lines and conveyor systems. They can connect directly to PLC DC output modules for seamless integration.

Renewable Energy & Storage: Used in the low-voltage auxiliary circuits of photovoltaic inverters and energy storage systems to reliably control cooling fans and miniature circuit breakers.

Commercial Buildings: Applied in building management systems for lighting control, HVAC fan coil units, and small elevator auxiliary circuits, where their low coil power consumption reduces energy loss.

E-Mobility & Transport: Serve as key switching components in the internal control circuits of EV charging piles and in auxiliary electrical systems for metros/light rail, meeting demands for high reliability and vibration resistance.

Medical Equipment: Found in devices like small sterilizers and analysers that use DC control power, where stable performance and low electromagnetic interference are critical for safety.

They are perfectly suited for automation because they can be directly interfaced with PLC DC output modules. This provides precise and reliable logic control for motors and other actuators without the need for additional interfacing devices, simplifying system design and improving response times.

In solar and storage applications, system stability is paramount. KRIPAL DC Contactors provide reliable switching for critical auxiliary functions like thermal management (cooling fans) and circuit protection. Their design ensures consistent performance in DC environments, contributing to the overall uptime and longevity of the inverter or battery system.

A key advantage in commercial buildings is energy efficiency. The low power consumption of the DC coils significantly reduces standby energy loss compared to some alternatives. This helps lower the long-term operational costs of lighting and HVAC control systems.
