Excellence in Solid State Technology available in Crydom’s DRH Series of Power Enhanced AC 3-Phase Contactors

Crydom introduces the DRH Series, a compact size solution for heating applications with loads up to 20 Amps

DRH Series Press Release Image

Crydom is pleased to announce the new DRH Series of AC Output Solid State Contactors. Based on the same technology and compact 45mm size of the SOLICON DRC, the most innovative compact DIN Rail Mount, IEC standard based contactors in the market, combines all the advantages of a solid state design with the functionality and simplicity of use of an electromechanical contactor.

View DRH Series

While the DRC series was intended for motor applications, the DRH Series, thanks to the enhanced power of 20 Amps on each channel, is intended to switch any resistive as well as inductive loads; it is the perfect solution in any heating application in market segments such as Plastic, Packaging, HVAC, Food & Beverage, Printing and Medical. This product is an ideal replacement of electromechanical contactors when higher reliability is needed or when fast cycling is frequent. Their compact size and easy installation make these devices an optimum solution in commercial and industrial applications, especially when retrofitting. Reliable operation is ensured by means of the integrated over-voltage protection, over-temperature protection, high I2t and surge current ratings and immunity conformance to industrial standards.

Main features include:

  • Rating up to 600 VAC, 18 A (3 controlled legs), 20 A (2 controlled legs)
  • Integrated over-voltage protection
  • Integrated over-temperature protection
  • Alarm output in case of over-temperature
  • Enclosed heat sink eliminates the need for protective earth connection
  • 4-32 VDC or 90-280 VAC control input
  • Multicolor LED with input status and alarm indication
  • UL 100 kA Short Circuit Current Rating
  • C-UL-US listed, CE compliant

These features make the DRH Series unique in the market with a broader working temperature range (-10ºC to +70ºC), better resistance to surge current (716 Amps), higher resistance to short circuit (2560 A2sec), smaller size and a greater life span (50 million cycles).

All these premium features are included in both available DRH models:

  • DRH3P60x18x, Solid State Contactor 3 controlled legs, 18 Amps @40°C
  • DRH3P60x20x, Solid State Contactor 2 controlled legs, 20 Amps @40°C

The DRH Series is available in either instantaneous turn-on (typically used for inductive loads or motor loads) or zero voltage turn-on (more often used with resistive loads). Both are available with either 2 or 3 controlled legs.

The high current rating is the result of an innovative design that increases the air flow thus improving the thermal performance. DRH contactors also feature over-temperature protection to avoid overheating in case of a fan malfunction. The internal temperature is constantly monitored and the fan is switched only when necessary in order to extend its lifetime. The LED makes the operator aware of internal temperature rising before it reaches its limit; once reached, the contactor will safely switch off and the alarm output contact will switch on.

Crydom’s DRH Series contactors are C-UL-US Listed and compliant to IEC 60947-4-2 requirements. They are also CE compliant to the Low Voltage Directive as well as the EMC and RoHS Directive.
