BLC DC Breaker Landing Cabinet
The C&C Power BLC DC Breaker Landing Cabinet allows for multiple battery strings to be terminated to a common bus protected by a DC rated circuit breaker. This isolates the battery strings from the UPS for safety purposes and to provide ease of maintenance on either the battery strings or the UPS.
The BLC DC Breaker Landing Cabinet is available with current capacities ranging from 1600 to 3000 Amperes at up to 600VDC.
The circuit breakers are available with the following optional accessories:
Auxiliary Switch: For applications requiring remote on or off indication. Each auxiliary switch comprises of an open, closed, and common contact.
Bell Alarm: The bell alarm switch is closed when the circuit breaker has been tripped due to a short circuit, shunt trip, or under-voltage trip. The bell alarm switch is automatically opened when the circuit breaker is reset.
Shunt Trip: Circuit breakers may be tripped from a remote location with the use of a shunt trip. Shunt trips can be activated by applying a specified voltage through the shunt trip contacts which automatically cause the circuit breaker to trip.
Under-voltage (UV) Trip: The UV trip monitors a voltage across a set of contacts. If the voltage drops to a value below 35% of the specified coil rating, the under-voltage trip device trips the circuit breaker. The operation is instantaneous and the circuit breaker cannot be reset until the voltage returns to at least 85% of the specified coil voltage.
