FAQs
This 4P 160A change-over switch is designed for base mounting and screw-terminal connections, matching typical ABB OT and similar low-voltage switchgear installations. Verify cabinet clearance for the 205 mm width and 160 mm depth, then align mounting holes and terminal spacing to your existing enclosure to ensure a smooth retrofit with minimal rewiring.
Important specs include: 4 poles, 160 A rated current at 380–415 V, Ui 1000 V insulation, Uimp 12 kV impulse withstand, Ith 160 A at Θ = 40 °C, Icw 8 kA for 1 s, and screw terminals with 15–22 N·m tightening torque. These ensure safe operation, adequate fault protection, and compatibility with standard industrial feeders.
Yes. Its base mounting and included shaft simplify integration into existing panels. The lockable 0-position and door interlock reduce risk during maintenance, while 160 A capacity supports high-demand lines. Use the provided data sheet OTC1GB and OT-C manuals to map wiring, interlock logic, and replacement timelines for a smooth retrofit.
The product carries CE Declaration of Conformity, RoHS compliance, and DNV certification, with CMRT and SCIP records. These demonstrate regulatory compliance, environmental responsibility, and risk management across supply chains, aiding audits, supplier qualification, and adherence to European and global standards for electrical protection components.
The combination of a robust 160 A rating, secure locking, interlock protections, and straightforward installation reduces downtime during maintenance and minimizes wiring errors. In OEM panels and transfer-switch applications, this translates to lower labor costs, faster commissioning, and lower risk of electrical incidents over the lifecycle of the installation.
