The Siemens 5SL7220-8RC is a SENTRON 5SL7 miniature circuit breaker (MCB) designed to provide reliable protection against overload and short-circuit conditions in compatible electrical installations. This MCB features a 20 A rated current, 2-pole configuration, D tripping characteristic, 415 V AC rated voltage and 15 kA short-circuit breaking capacity.
The Siemens 5SL7220-8RC 20A 2-pole MCB is suitable for electrical circuits where a D tripping characteristic is required. The D curve is generally selected for applications where connected equipment can produce comparatively high starting or inrush currents. This makes the MCB suitable for appropriately designed circuits involving motors, transformers, inductive loads and selected industrial equipment.
The 2-pole configuration provides coordinated protection and switching for compatible two-pole circuits. The MCB can be incorporated into electrical distribution boards, industrial control panels, machinery panels, automation systems and OEM electrical assemblies.
With a 20 A rated current, the 5SL7220-8RC is suitable for appropriately designed medium-current circuits. The connected load, conductor capacity, installation conditions and coordination with upstream and downstream protective devices should be evaluated during selection.
The 415 V AC rating supports use in compatible electrical distribution systems. Its combination of 20 A current rating, 2 poles, D characteristic and 15 kA breaking capacity makes it suitable for professional electrical protection applications.
As part of the Siemens SENTRON 5SL7 series, the 5SL7220-8RC can be considered by panel builders, OEMs, electrical contractors, system integrators and industrial maintenance teams.
The Siemens 5SL7220-8RC 20A 2-pole D curve MCB can be considered for:
The Siemens 5SL7220-8RC provides dependable circuit protection for applications requiring a 20 A, 2-pole MCB with D characteristic and 15 kA breaking capacity. Its D tripping curve is intended for suitable circuits where connected equipment can experience relatively high starting or inrush currents.
This makes the MCB a practical option for appropriately designed motor, transformer, inductive-load and industrial equipment circuits. The D characteristic can accommodate higher startup-current conditions where required while maintaining protection against sustained overcurrent and short-circuit conditions.
The 15 kA breaking capacity provides a high specified short-circuit interruption capability for suitable electrical installations. The prospective short-circuit current should always be evaluated to ensure the protective device is appropriately rated for the intended circuit.
The 2-pole construction provides coordinated protection and switching for compatible two-pole circuits. This makes the device suitable for electrical distribution boards, control cabinets, machinery panels, OEM assemblies and other suitable electrical installations.
The 20 A rated current makes the 5SL7220-8RC suitable for appropriately designed medium-current circuits. Correct coordination between the MCB, cable size, connected equipment and upstream/downstream protection is essential for reliable electrical protection.
The 415 V AC rating supports use in compatible electrical distribution systems, making the MCB suitable for various industrial and commercial panel applications where the system voltage and load characteristics match the device ratings.
The Siemens SENTRON 5SL7 series provides a practical solution for professional circuit protection requirements. The 5SL7220-8RC can therefore be considered for OEM panels, industrial machinery, automation systems, electrical distribution boards and control applications.
