The 3SB electro mechanical devices provide fast trip response with low current draw at 28 VDC. For adaptability to aircraft cockpit panel mounting, they are packaged in a standard MS 26574 style thermal circuit breaker configuration. This fast trip/low current performance provides the opportunity for system level savings. It enables the designer to potentially downsize the system power source and eliminate expensive I/O boards or other electronics while also reducing the amount of cabling required.

Changes in training schemes normally entail system rewiring to reconfigure the simulator, which becomes labor intensive and costly. With the incorporation of a 3SB device the training changes can easily be achieved through system software — without the time and cost associated with rewiring.

Klixon® simulator circuit breakers also provide the same tactile feel as standard Mil qualified breakers for superior training realism.

Klixon® circuit breakers offer flexibility by offering replaceable ampere rating inserts. (To order different amp rating insert tabs, reference part number 27515.) Attached to the top of the pushbutton actuator, they match the current rating used in the actual aircraft. These inserts can be rotated within the pushbutton to meet your cockpit configuration needs.

An optional auxiliary switch for remote indications and a variety of connection alternatives are also available.
