Klixon Aircraft Circuit Breakers 3SB Simulator Series

Single–phase
28VDC, fast trip response
Same tactile feel of industry aircraft breakers

Klixon 3SB series simulator circuit breaker was developed by Sensata Technologies to meet the growing needs of the commercial and military simulator industry. Due to the high operational coast of live training, more and more training is being conducted on simulators. The realism and complexity of tomorrow’s simulators will require a circuit breaker that can provide the same “look and feel” of industry accepted circuit breakers in order to create a superior training environment.

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.

Rated to 75VDC and 250VAC, 60Hz

The 2EP Series is a sub-miniature push-pull thermal circuit breaker adapted from a proven aerospace circuit breaker design to offer a truly high performance solution to the market place at a competitive price. The push-pull design of the 2EP decreases the risk of accidental tripping; temperature compensation allows it to maintain a constant calibration across temperature extremes; the thermal design allows a sufficient delay to minimize nuisance trips; the robust latching design offers high shock and vibration performance; the multi break design offers high interrupt performance and ratings at both AC and DC voltages. The 2EP is U.L. recognized (1077) and rated to 75 VDC, and 250 VAC at 60 Hz. All these features combine to make a solution which is ideally suited for industrial equipment, radars, medical and dental equipment, electronic control systems, recreational vehicles, telecom equipment, power supplies, and test equipment, to name a few.

The 2EP series is available in three configurations:

Using a bimetal, snap acting disc as the sensing and actuating element, the Klixon small frame P series thermal circuit breaker provides trouble-free over-current protection for harsh environments. Similar in construction to the C series device, the P is used in applications such as military vehicles and equipment where more precise ultimate trip characteristics are required.

Available in two configurations:
PDA: Automatic reset.
PDM: Manual reset.

AT SERIES SWITCHES

AT Series: The AT basic switch is the standard device in the AT family, capable of switching up to 3 amps at 28 VDC into resistive loads.

3AT Series: Higher ambient temperatures.

4AT Series: This device is designed to operate at temperatures lower than the standard AT switch.

10AT Series: This device is designed to operate at temperatures lower than the standard AT switch. Accordingly, this switch finds much use in space applications. For higher current capability than the standard AT switch.
