Product Description

Siemens 5SL7402-8RC MCB 2A 4-Pole D Characteristic 15kA

The Siemens 5SL7402-8RC is a SENTRON 5SL7 miniature circuit breaker (MCB) designed for reliable protection against overload and short-circuit conditions in suitable electrical installations. This MCB features a 2 A rated current, 4-pole configuration, D tripping characteristic, 415 V rated voltage and 15 kA short-circuit breaking capacity. The 5SL7 range is specified for 240/415 V AC systems and is manufactured according to the applicable IS/IEC 60898-1 requirements.

The Siemens 5SL7402-8RC 2A 4-pole MCB is intended for circuits where a low-rated protective device is required along with a D characteristic. The D curve can be appropriate for selected loads that experience higher starting or inrush currents, subject to proper circuit design and protection coordination.

Its 4-pole configuration makes it suitable for compatible multi-phase electrical systems where four-pole circuit protection and switching are required. It can be incorporated into suitable distribution boards, industrial control panels, automation panels, machinery control systems and other electrical assemblies.

The 15 kA breaking capacity provides a high specified short-circuit interruption capability for installations where the prospective short-circuit current requires a protective device of this rating. The actual fault level of the installation should always be assessed before selecting the MCB. Siemens documentation and current product listings identify the 5SL7 D-characteristic range as having up to 15 kA breaking capacity.

With a 2 A rated current, the 5SL7402-8RC is intended for appropriately designed low-current circuits. It can be considered for suitable auxiliary, control, signalling and other electrical circuits where the connected load and conductor capacity are correctly matched to the MCB rating.

The D tripping characteristic is an important selection factor. Compared with a C-characteristic MCB, a D-characteristic device is intended for applications where higher transient starting currents may occur. The correct characteristic should therefore be selected according to the actual load and installation requirements.

As part of the Siemens SENTRON 5SL7 family, this MCB is suitable for professional electrical protection applications and can be considered by panel builders, OEMs, electrical contractors, system integrators and industrial maintenance teams.

Benefits

The Siemens 5SL7402-8RC provides dependable circuit protection for suitably designed low-current circuits requiring a 2 A, 4-pole MCB with D characteristic. Its compact modular design makes it suitable for integration into electrical panels and distribution systems where space-efficient circuit protection is required.

The D characteristic makes the device suitable for selected applications where the connected equipment can generate relatively high starting or inrush currents. This can include certain inductive or specialized loads, although the final MCB selection should always be based on the equipment characteristics and complete protection design.

The 15 kA breaking capacity provides a high specified fault-interruption capability for suitable installations. This is particularly relevant where the calculated prospective short-circuit current requires a protective device with an appropriate breaking capacity. The actual installation fault level must be verified before selection.

The 4-pole construction provides a practical solution for compatible multi-phase systems requiring coordinated protection and switching across four poles. It can help panel builders maintain an organized arrangement in distribution boards, control panels and industrial electrical assemblies.

The 2 A rated current makes this MCB suitable for appropriately designed low-current circuits. It can be considered for selected auxiliary and control applications where the circuit current, conductor capacity and equipment requirements are compatible with the protective device.

The 415 V rating supports use in compatible electrical distribution systems within the specified voltage range. The 5SL7 series is specified for 240/415 V AC, 50–60 Hz applications.

The Siemens 5SL7 series also offers compatible accessories for suitable configurations, allowing electrical protection and signalling arrangements to be expanded where required.

The Siemens 2 A 4P D curve 15 kA MCB can be considered for suitable projects across Faridabad, Delhi NCR, Noida, Gurgaon/Gurugram, Ghaziabad, Punjab, Mumbai, Pune, Ahmedabad, Hyderabad, Bengaluru/Bangalore, Chennai, Kolkata, Jaipur, Chandigarh, Ludhiana and other major industrial and commercial locations across India.

Always verify the connected load, conductor rating, prospective short-circuit current, system voltage and coordination with upstream and downstream protective devices before installation.
