Siemens 4 Pole 25 kA Frame MCCB Thermal Magnetic Trip Unit, (FTFM) 3VT1 Series

Siemens 4 Pole 25 kA MCCB Thermal Magnetic Trip Unit (FTFM) 3VT1 Series are essential components in electrical distribution systems, providing reliable protection against overloads and short circuits. The Thermal Magnetic Trip Unit is a crucial element within these MCCBs, offering dual-functionality for both thermal and magnetic protection.

Thermal protection operates by sensing the heat generated by excessive current flow, triggering the trip mechanism to disconnect power when temperatures reach dangerous levels due to prolonged overload conditions. This safeguards the MCCB and connected electrical systems from damage caused by overheating.

Meanwhile, magnetic protection responds swiftly to sudden, high-current surges, such as those caused by short circuits. The magnetic trip mechanism detects the rapid increase in current and promptly trips the MCCB to interrupt the circuit, preventing damage to equipment and minimizing downtime.

Siemens designs its MCCB Thermal Magnetic Trip Units with precision engineering and advanced technology, ensuring high-performance protection for a wide range of applications, from industrial machinery to commercial facilities. With their robust construction and dependable operation, Siemens MCCBs with Thermal Magnetic Trip Units contribute to the safety and reliability of electrical systems, providing peace of mind to users and helping to maintain uninterrupted operations.
