Siemens HHFD Series circuit breakers are designed to protect industrial machinery and equipment from damages caused by short-circuit and overload occurrences. These UL-listed breakers come with a molded case to hold the current-carrying components, trip devices and other mechanisms within a compact space. The thermal-magnetic trip mechanism of these devices overrides mild current overloads but instantly responds to heavy fluctuations for user safety. They further come with a bolt-on mounting facility to offer compatibility with panelboards and switchboards. Choose from a wide range of these Siemens circuit breakers available in current ratings ranging from 110 to 250A, on Raptor Supplies.

Molded case circuit breakers are designed to prevent the flow of faulty power supplies into sensitive electrical equipment that may cause overloads and short circuits. With current ratings up to 1600A, these units are ideal for isolation applications in large PV systems. Raptor Supplies offers a wide range of these MCCBs from brands like ABB, Square D, Eaton, General Electric and Siemens. Square D circuit breakers come equipped with a thermal-magnetic trip unit which instantly opens under faulty currents and are capable of providing both time-delayed and instantaneous current limiting functions. These units feature an I-line type configuration at the ON end for facilitating bus connections in panelboards and lugs at the OFF end for cable connection. General Electric molded case circuit breakers feature a programmable electronic trip unit which accentuates the toggle when the current exceeds the predetermined value. These breakers come equipped with bolt-on type terminals for easy installation in reverse-feed applications. They are available in 2 and 3 pole options with a maximum voltage rating of 600VAC on Raptor Supplies.
While both molded case circuit breakers and conventional circuit breakers serve the same primary purpose of protecting electrical circuits, MCCBs are a specific type of circuit breaker with a molded case for added durability and protection.
Once the fault or overload is resolved, you can reset the MCCB to restore power to the circuit.
Molded case circuit breakers are designed for higher current ratings and are used in industrial settings with heavy machinery, while MCBs are smaller and designed for residential or light commercial applications with lower current ratings.
Yes, MCCBs are commonly used in three-phase systems. Brands like WEG, Siemens and ABB come in various configurations to suit single-phase or three-phase applications.
Selecting the right MCCB involves considering factors such as the system's voltage, current rating, environmental conditions and specific protection requirements.
