Circuit Breaker BM series
Application
BM series circuit breaker for equipment (hydraulic-magnetic circuit breaker) is used in the power system with rated current from 0.1A to 30A, rated voltage up to AC250V (50/60Hz) or DC80V. It provides overload, short circuit protection. It can also be used for infrequent close or open. The application fields are computer and peripheral equipment, industrial automatic control system, telecom equipment, power supply system, UPS, railroad, marine, spacecraft, elevator, portable power supply and so on.
Specification
2.1 Standards: IEC 60934, GB 17701, UL1077, UL489A

Packing and depositing
The products should be stored in the warehouse where there is ventilation. The relative humidity there should not exceed 80%, and the ambient temperature there is between -25℃ to +60℃. In addition, there should not be acidic, alkaline and corrosive gas in the air. The products should not be deposited more than 3 years in the above mentioned conditions since the producing date
Notices
9.1 Do not disassemble the breaker privately.
9.2 Attention to live part when the breaker is energized and avoid touching them.
9.3 Please make sure reliable connection to avoid fault tripping or damage of terminal caused by exceptional heat resulting from unsuitable connection.
