MCB

The result of poor coordination between protection devices can significantly increase the amount of downtime caused by small faults. Therefore, a final distribution circuit will require a trip element that trips quickly, resets easily and can fit within a narrow distribution panel layout. An MCB is provided for these types of applications where reliable overload and short-circuit protection are needed for all types of lighting, control wiring or small power supply feed.

Perfect Automation & Innovation supply these breakers for systems that operate on a continuous basis and require quick fault isolation without interfering with upstream supply.

The current rating (or trip value) and the tripping curve are based on the actual cable size, inrush condition and load pattern connected to the final circuit. Thermal/magnetic protection mechanisms are designed to detect both sustained overload and fast-transient fault currents, thereby safeguarding the circuit from potential hazards caused by everyday operation of the circuit. Compact designs with high circuit density help distribute more circuits while still providing adequate access for the wiring to be installed properly within a distribution board.

Our MCB (Miniature Circuit Breakers) are ideal for applications that require dependable overload and short-circuit protection for lighting, control wiring, and small power feeders. At Perfect Automation & Innovation, we manufacture our MCBs for systems that operate continuously and require rapid isolation of faults to be ensured without disturbing the supply of power upstream.

The current rating of MCB's and the trip curves of MCB's are determined based on actual cable size, condition of inrush, and the load pattern of the connected motor. The thermal-magnetic mechanism operates & reacts not only to sustained overloads but also to fault conditions to promote safe operation of the circuit during daily operations. The compact design of MCB's enables higher density of circuits within the distribution board while also enabling proper access in the manner of wiring.

The use of clear contact position indicators allows maintenance personnel to identify trip conditions without requiring any other tools to do so. The construction of the terminals allows for secure fastening which reduces the possibility of heat build-up due to poor connections. The mounting arrangement allows for replacing of MCBs quickly during service operations, thereby minimizing the time of facility shutdown for a running business.

MCBs can be used with auxiliary contacts and busbar systems, therefore enabling organized assembly of the control panel, and also allowing for the expansion of circuits in the future.

These MCB's are commonly utilized in Control Panel construction; Commercial Distribution Boards; Utility Rooms; and Automation System applications where reliable protection of circuits; safe operation; and fast restoration of supply are part of the day-to-day maintenance of Electrical Systems.
