DESCRIPTION

Circuit Breaker BC series

Application

BC series circuit breaker for equipment (hydraulic-magnetic circuit breaker) is used in the power system with rated current up to DC400A and AC100A, rated voltage up to AC277/480V (50/60Hz) or DC125V. 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.

Packing and depositing

The products should be stored in the warehouse where there are 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.

Notice
10.1 Do not disassemble the breaker privately.
10.2 Attention to live part when the breaker is energized and avoid touching them.
10.3 Please make sure reliable connection to avoid fault tripping or damage of terminal caused by exceptional heat resulting from unsuitable connection.
10.4 Please maintain the distance of 45mm from the arc jet slot of the product (LINE side) when installation in case there is short circuit breaker due to arc jet.
10.5 The breaker should be mounted within 5° of the mounting plane in case the characters of the product are affected.
10.6 The fasten torque of screw is 0.5N.m.。
