1SDA059014R1 ABB E6H/MS 6300 4P W MP Switch Disconnector 6300 A

Why Choose the ABB E6H/MS 6300 4P W MP Switch Disconnector?

The ABB E6H/MS 6300 4P W MP, order code 1SDA059014R1, is a heavy-duty SACE Emax air switch disconnector moving part engineered for high-current switching and isolation in demanding low-voltage power distribution systems. Built on the ABB E6 frame, this four-pole device provides a rated uninterrupted current of 6300 A and forms the moving portion of a withdrawable SACE Emax installation.

The E6H/MS 6300 combines ABB's service-friendly withdrawable architecture with the H short-circuit performance level. It provides a rated short-time withstand current of 100 kA for 1 s and 85 kA for 3 s, delivering substantial withstand capability for major incoming, bus-tie and distribution duties in high-power electrical installations.

Rated for operation up to 690 V AC or 250 V DC, with a rated insulation voltage of 1000 V and rated impulse withstand voltage of 12 kV, the E6H/MS 6300 is designed for substantial low-voltage distribution duties. As an /MS switch disconnector, it provides switching and isolation without an integral overcurrent trip unit, making it suitable for installations where circuit protection is provided separately.

Key Advantages

• Exceptional 6300 A rated current for major low-voltage power distribution systems.
• Four-pole withdrawable construction supports service-friendly high-power switchboard design.
• Supplied as the moving part for a compatible SACE Emax withdrawable assembly.
• Rated for operation up to 690 V AC or 250 V DC.
• High 100 kA short-time withstand current for 1 s.
• Robust E6 frame construction for demanding industrial and infrastructure applications.

Reliable High-Current Isolation for Major Power Distribution

The ABB E6H/MS 6300 is designed to provide dedicated high-current switching and isolation in systems where overcurrent protection is supplied separately. Its 6300 A continuous-current capability and high short-time withstand ratings make it particularly suitable for critical distribution points handling very substantial electrical loads.

The withdrawable design provides an important service advantage because the moving portion can be disconnected and withdrawn from its corresponding fixed section. Combined with its four-pole configuration and 100 kA one-second withstand capability, the E6H/MS 6300 provides a robust solution for large industrial, infrastructure and high-capacity power distribution assemblies.

Typical Applications

• High-current industrial low-voltage distribution switchboards.
• Main incoming power isolation.
• Four-pole power distribution and isolation.
• Bus-tie and busbar isolation duties.
• Withdrawable high-capacity switchgear assemblies.
• Large industrial plants and manufacturing facilities.
• Infrastructure and major commercial power distribution systems.
