1SDA059085R1 ABB E1/CS 1250A 3-Pole Withdrawable Sectionalising Truck Moving Part

Why Choose the ABB 1SDA059085R1 E1/CS 1250 Sectionalising Truck?

The ABB 1SDA059085R1 is a SACE Emax E1/CS 1250 sectionalising truck moving part designed for sectionalising and isolation duties in low-voltage industrial power distribution systems. Rated at 1250 A, this three-pole withdrawable device provides a robust solution for switchboards where circuit sections need to be interconnected or isolated without incorporating an overcurrent protection trip unit.

Part of the proven ABB SACE Emax platform, the E1/CS uses the E1 frame in a dedicated sectionalising-truck configuration. The W MP designation identifies this product as the moving part of a withdrawable assembly, allowing it to be inserted into and removed from the appropriate fixed part as part of a serviceable switchgear installation.

The 1SDA059085R1 provides a rated operational and uninterrupted current of 1250 A in a three-pole configuration. It is specified for 690 V AC operation, with a rated insulation voltage of 1000 V and rated impulse withstand voltage of 12 kV, making it suitable for substantial industrial distribution assemblies.

Reliable Sectionalising for Industrial Power Distribution

A sectionalising truck is used within switchgear to provide a conductive connection between sections of an electrical distribution system while allowing that connection to be isolated when required. Unlike a circuit breaker equipped with a protection trip unit, its primary purpose is sectionalising, coupling and isolation within the switchboard rather than automatic overcurrent protection.

The ABB SACE Emax E1/CS 1250 combines a 1250 A current rating with a withdrawable moving-part design, allowing the device to form part of serviceable switchgear architectures. Its three-pole construction, 690 V AC operational rating and Emax mechanical platform make it suitable for substantial industrial distribution systems where reliable sectionalising is required.

Typical Applications

• Industrial low-voltage switchboards.
• Busbar sectionalising and coupling arrangements.
• Power distribution assemblies.
• Withdrawable industrial switchgear.
• Manufacturing and process plant electrical distribution.
