FAQs
The 1SCA103953R1001 is designed for base-mounted installations with screw terminals, supporting high-current main circuits up to 2000 A. Its four-pole construction (4P) suits large switchgear assemblies and OEM panels, while compatibility with standard mounting footprints simplifies retrofits and new builds alike. Ensure the enclosure provides enough clearance for 664 mm width and 335 mm depth, and verify torque specifications of 50–75 N·m for secure terminations.
Key ratings include a rated operational current (Ie) of 2000 A for AC-21B, AC-31B, and AC-33B configurations, Ui of 1000 V, Uimp of 12 kV, and Icw of 55 kA rms for 1 second. The switch is main-circuit rated for 1000 V, with a four-pole arrangement and a power loss of about 55 W per pole. These specs support robust performance in high-current switching applications.
Front protection is rated IP20, offering protection against contact with non-hazardous parts while not being fully dust-tight. The unit is designed to withstand electrical surges with a rated impulse withstand voltage (Uimp) of 12 kV and a rated insulation voltage (Ui) of 1000 V, ensuring safer operation under transient conditions common in industrial power systems.
The product supports CE conformity (Declaration of Conformity), RoHS, and REACH compliance, with an accompanying DNV certificate for additional oversight. These certifications help meet European regulatory requirements and supplier qualification criteria for critical electrical equipment used in industrial environments.
The padlockable 0-position and I/II door interlock features enhance safety and reduce maintenance risk by preventing unintended operations. Its high current rating and robust construction lower fault-related downtime, contributing to a shorter total cost of ownership. In addition, its RoHS/REACH compliance simplifies regulatory audits, while base mounting and screw-terminal connections shorten installation and service times.
