Product Description

Siemens 5SL7320-8RC MCB 20A 3-Pole D Characteristic 15kA

The Siemens 5SL7320-8RC is a SENTRON 5SL7 miniature circuit breaker (MCB) designed for dependable protection against overload and short-circuit conditions in suitable electrical installations. This MCB features a 20 A rated current, 3-pole configuration, D tripping characteristic, 415 V rating and 15 kA short-circuit breaking capacity. Product documentation confirms the 3-pole design, D characteristic and 15 kA breaking capacity.

The Siemens 5SL7320-8RC 20A 3-pole MCB is suitable for electrical circuits where a D-characteristic protective device is required. The D curve is generally selected for applications where equipment can produce relatively high starting or inrush currents. This can make it appropriate for selected motor, transformer, inductive-load and industrial equipment circuits, provided the protection design is correctly matched to the connected load.

With its 3-pole configuration, the MCB is intended for compatible three-phase electrical systems. It can be used in suitable distribution boards, industrial control panels, machinery panels, automation systems and electrical switchboards.

The 15 kA short-circuit breaking capacity provides a high specified interruption capability. The available product data specifies 15 kA according to EN 60898 and IEC 60947-2. The prospective short-circuit current of the installation should nevertheless be checked before selecting the protective device.

The 20 A rated current makes this MCB suitable for appropriately designed circuits where the load current and conductor capacity are compatible with the protective-device rating. Proper coordination with upstream and downstream protection is also important.

The product is designed for infrastructure and industrial applications and is specified as halogen-free, sealable and silicon-free.

Benefits

The Siemens 5SL7320-8RC provides dependable circuit protection for applications requiring a 20 A, 3-pole MCB with D characteristic and 15 kA breaking capacity. Its D tripping curve is intended for suitable circuits where higher starting or inrush currents may occur.

This makes the MCB a practical option for appropriately designed applications involving motors, transformers, inductive equipment and selected industrial loads. The D characteristic can help accommodate expected starting-current peaks while maintaining overcurrent protection when correctly applied.

The 15 kA breaking capacity provides a high specified short-circuit interruption capability for suitable installations. This is particularly relevant in industrial and distribution environments where the available fault current can be significant.

The 3-pole construction provides coordinated protection and switching for compatible three-phase circuits. This makes the device suitable for installation in control cabinets, distribution boards, machinery panels and electrical switchboards.

The 20 A current rating makes the 5SL7320-8RC suitable for appropriately designed lower-to-medium current circuits. The MCB rating should always be coordinated with the connected load, conductor size and overall electrical protection system.

The 415 V rating supports use in compatible three-phase electrical distribution systems. The product documentation also specifies a maximum 440 V AC for multi-phase operation.

The device's halogen-free, sealable and silicon-free construction can also support professional electrical-panel applications where these product characteristics are desirable.
