DD11 and DD21 – New with Rotated Switch

  • Designed for medical applications
  • 2-pole fuseholder
  • DD11: 2-pole switch
  • DD21: 1- or 2-pole switch
  • V-Lock cord retention

The Schurter DD11 and DD21 power entry modules, which are already used in a variety of applications, are now available in a version with a rotated switch. This meets the specific requirements of medical applications where the switch (rocker) must be rotated by 180°: the switch-on position is at the top and the switch-off position is at the bottom.

With their ultra-compact design, the power entry modules DD11 and DD21 are the ideal choice for low-profile designs. They are all-in-one solutions comprising an IEC C14 connector, a fuse holder and a switch. All the individual components are pre-wired. This significantly reduces assembly time. The compact design and three-in-one functionality allow less space to be used in the equipment. The power entry modules DD11 and DD21 are ideal for applications involving high transient loads.

New with 180° Rotated Switch
Schurter newly offers two different variants with switch-on and -off position rotated by 180°, thus meeting the requirements of many medical electronic applications.

V-Lock Cord Retention
All DD11 and DD21 modules, including these new variants with rotated switch, are equipped with the proven V-Lock cord retention system as standard.

Application Areas
The new variants are suitable for applications according to IEC/UL 62368-1 (Audio/video, information and communication technology equipment), IEC 60601-1 (Medical electrical equipment) and IEC 60335-1 (Electrical appliances for household and similar purposes). They also meet the requirements for appliances in unattended use. This includes the enhanced requirements of glow wire tests acc. to IEC 60695-2-11 or -12 & -13.
