FAQs
Install with base mounting on a suitable panel surface using screw terminals rated for the appropriate conductor size. Ensure the terminals are tightened to 15–22 N·m as per IEC 60947-1. Maintain proper clearance and alignment for the four-pole assembly, and integrate the handle extension only during manual operation. Verify accessibility for padlocking at the 0-position.
The device supports a conventional free-air current of Ith 160 A at Θ = 40 °C and a fully enclosed current Ie = 160 A. It is rated for Ui 1000 V and Uimp 12 kV, with a Rated Operational Current Ie across 380–415 V, 500 V, and 690 V up to 160 A. A 4P configuration enables simultaneous switching of all phases.
Yes. The product carries CE conformity with Declaration of Conformity and RoHS/REACH declarations. It aligns with CMRT reporting and AB B’s environmental and safety standards, supporting regulatory compliance in European and global markets for electrical protection and switchgear components.
Padlocking is available at the 0-position, with door interlocks in the I- and II-positions and when padlocked, ensuring that the circuit cannot be energized during servicing. The optional handle extension allows smooth manual operation, while the lockout mechanism helps enforce safe working conditions and prevents accidental energization.
