Product Description

The Ex9BP UL1077 Miniature Circuit Breaker is a DC miniature circuit breaker with the following features:

šŸ›”ļø
Compliance Standard
It complies with the UL 1077 standard and can provide overcurrent protection for branch circuit devices.
⚔
Rated Current
The rated current range is from 10A to 63A, and its tripping characteristic range is 9.6 to 14.4 times the rated current (9.6 - 14.4In), with a C-type tripping curve.
šŸ”Œ
Rated Voltage & Connection
Supports rated voltages of 300Vdc and 600Vdc. Features a polarity-free design supporting non-polarised connection, ensuring wiring convenience and minimizing error risks.
šŸ’„
Breaking Capacity
The breaking capacity is 6kA, allowing it to quickly cut off the circuit when a short-circuit fault occurs within the specified range to avoid fault expansion.
šŸŒ”ļø
Environment & Lifespan
Wide ambient temperature range from -30°C to +70°C. Delivers robust durability with an electrical life of up to 6,000 operations and mechanical life up to 20,000 operations.
āš™ļø
Application Scenarios
Perfectly suited for over-current protection in DC circuits, such as in photovoltaic module combiner boxes and charging systems.
