Users should verify actual device performance in their specifi c applications. Caution when using Breaker Before using the breaker, please fully read the DESIGN AND HANDLING CAUTIONS stated below so that there will be no breaker performance deterioration and/or damage to the breaker body or terminal. DESIGN CAUTIONS 1. Use within the electrical ratings specifi ed in this data sheet. If used over the rating of voltage or current, ON-OFF life m ight be impacted and contact may be deteriorated due to breaker arm damage. 2. If used over the electrical rating, the circuit may not open safely. Please test your device for any abnormalities and confi rm that the breaker will open the circuit safely in your device. 3. Mount the breaker on your device where heat is the highest in order to transfer it effectively to the breaker. 4. After the breaker is mounted, affi x it so that the breaker body and terminals will not move. If not affi xed, breaker resistance could increase or contact open due to stress during handling or vibration/shock during transportation. 5. Mount the breaker body and terminals in a straight and fl at direction. If the body and terminals are mounted in a twisted co ndition, breaker resistance could increase or create body damage. 6. If breaker is to be resin-molded, test and evaluate to determine whether the breaker can be used effectively. 7. The breaker cannot be used as a repetitive ON-OFF thermostat. 8. The breaker is not washable. Do not wash. 9. The breaker is not designed nor guaranteed for fl ow, refl ow or hand-soldering applications. If such application is required, test and evaluate in your specifi c application to confi rm that the breaker can be used. 10. When mounting and after mounting the breaker, do not apply supersonic vibration. Vibration and heat may cause the breaker resistance to increase or may cause body damage. If you apply supersonic vibration after mounting the breaker, test and evaluate in your specifi c application to confi rm that the breaker can be used. 11. Do not use the breaker in the following abnormal environments: a) Water, oil, chemicals or organic solutions b) Direct sunlight, outdoor exposure, dust c) Dew condensation, allowing the breaker to get wet d) Salt breeze, chlorine, hydrogen sulfi de, ammonium, sulfi de-oxidation, hydrogen chloride, and anywhere there is a possibilit y of generating corrosive gas such as ulfurous acid gas e) Strong static electric charge or electromagnetic wave 12. Thie breaker is not designed or tested for, and should not be used in aerospace, airplane, nuclear, military, life-sustaining medical and other related equipment.
