Siemens 5SL7463-8RC MCB 63A 4-Pole D Characteristic 10kA

The Siemens 5SL7463-8RC is a SENTRON 5SL7 miniature circuit breaker (MCB) designed for reliable protection against overload and short-circuit conditions in electrical installations. This MCB is rated for 415 V, features a 4-pole configuration, D tripping characteristic, 10 kA short-circuit breaking capacity, and a 63 A rated current.

The Siemens 5SL7463-8RC 63A 4-pole MCB is suitable for electrical circuits where higher inrush currents may occur. Its D characteristic provides a higher magnetic trip threshold compared with B and C characteristics, making it appropriate for selected applications involving motors, transformers and other loads with significant starting or inrush currents, provided the complete electrical installation is correctly designed.

The 4-pole configuration makes this MCB suitable for compatible multi-phase electrical distribution systems where four poles require protection and switching. It can be incorporated into distribution boards, industrial control panels, machinery panels and other electrical assemblies where a 4-pole protective device is required.

With a 10 kA breaking capacity, the 5SL7463-8RC is designed to interrupt specified short-circuit fault currents within its applicable ratings. This helps protect conductors and connected electrical equipment against damage caused by short-circuit and overload conditions.

As part of the Siemens SENTRON 5SL7 series, this miniature circuit breaker is designed for professional electrical distribution applications. It can be used by panel builders, OEMs, electrical contractors, system integrators and industrial maintenance teams looking for Siemens circuit protection solutions.

The 63 A D-curve MCB can be considered for appropriately designed industrial and commercial circuits where equipment starting current or inrush characteristics make a D characteristic suitable. MCB selection should always take into account the load profile, cable rating, prospective short-circuit current and coordination with upstream and downstream protective devices.

Benefits

The Siemens 5SL7463-8RC provides dependable circuit protection for electrical systems requiring a 63 A, 4-pole MCB with D tripping characteristic. The D characteristic is particularly useful for selected circuits where normal equipment operation involves relatively high starting or inrush currents.

This makes the MCB suitable for applications involving equipment such as motors, transformers and other inductive loads, provided the fault level and protection requirements of the installation are compatible with the device.

The 10 kA breaking capacity provides protection against specified short-circuit fault conditions. When correctly selected and coordinated, the MCB can help protect electrical wiring and connected equipment from overload and short-circuit events.

The 4-pole construction provides simultaneous switching and protection across four poles according to the electrical system design. This can help panel builders maintain an organized and efficient arrangement in distribution boards and industrial control panels.

The 415 V rating makes the 5SL7463-8RC suitable for compatible electrical distribution systems operating within its specified voltage rating. Its 63 A current rating provides a solution for higher-current circuits where the conductor and load characteristics are correctly matched.

The Siemens 5SL7 series also supports compatible accessories for selected configurations, allowing additional functions such as auxiliary signalling or residual current protection to be incorporated where applicable.
