1SDA059013R1 ABB E6H/MS 6300 3P W MP Switch Disconnector 6300 A

Why Choose the ABB E6H/MS 6300 3P W MP Switch Disconnector?

The ABB E6H/MS 6300 3P W MP, order code 1SDA059013R1, 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 three-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, together with the robust construction required 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. ABB /MS switch disconnectors are derived from corresponding Emax circuit breakers and retain their overall dimensions and accessory possibilities while omitting the overcurrent trip unit.

Key Advantages

• Exceptional 6300 A rated current for major low-voltage distribution systems.
• Three-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.
• AC-23A utilisation capability supports switching of motor loads and other highly inductive loads.

Key Features

• ABB SACE Emax E6H/MS series.
• 6300 A rated uninterrupted current.
• Three-pole (3P) construction.
• Withdrawable (W) moving part (MP) configuration.
• 690 V AC / 250 V DC rated operational voltage.
• 1000 V rated insulation voltage.
• 12 kV rated impulse withstand voltage.
• H short-circuit performance level.
• 2000-cycle electrical durability.
• 12,000-cycle mechanical durability.

Reliable High-Current Isolation for Major Power Distribution

ABB /MS switch disconnectors are derived from corresponding SACE Emax circuit breakers and retain their overall dimensions and ability to accommodate Emax accessories while differing through the absence of overcurrent trip units. The E6H/MS 6300 therefore provides dedicated switching and isolation where electrical protection is supplied separately, while its AC-23A utilisation category supports switching of motor loads and other highly inductive circuits within the applicable ratings.

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 exceptional 6300 A rating, three-pole construction and 100 kA one-second withstand capability, the E6H/MS 6300 is particularly suited to major industrial, infrastructure and high-capacity power distribution assemblies.

Typical Applications

• High-current industrial low-voltage distribution switchboards.
• Main incoming power 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.
