The 1250 A current rating paired with a four-pole arrangement delivers high-capacity switching for main feeders in demanding industrial environments, translating to fewer transfer interruptions and improved system availability. This feature directly impacts uptime and maintenance planning, enabling operators to schedule changes with confidence and reduce arc-related risks during source transfers. The 4P configuration supports simultaneous switching across phases, enhancing isolation integrity and enabling safe parallel operations in complex power networks used in manufacturing lines and data centers. Front-operated devices with base mounting simplify installation, allowing panels to be configured with minimal field wiring and reduced assembly time, thereby lowering labor costs and accelerating commissioning. Screw terminals with a 50 mm terminal width and a tightening torque of 50–75 N·m ensure robust, vibration-resistant connections in dirty or vibration-prone environments, improving long-term reliability and reducing retightening cycles. The device’s IP20 front protection, 1000 V rated insulation, and 12 kV impulse withstand provide strong protection against dust ingress and transient overvoltages, supporting compliance with safety standards in harsh industrial settings. ABB EcoSolutions compatibility and the documented environmental declarations (RoHS, Reach, CMRT) offer a clear path to responsible sourcing and regulatory compliance, reducing life-cycle risk for electrical protection and switchgear portfolios. The option to order the handle and shaft separately allows customization for installation constraints and operator ergonomics, improving user acceptance in field configurations. These features collectively support faster commissioning, lower total cost of ownership, and safer transfer switching in critical applications such as emergency power supply, critical process lines, and parallel feeder configurations.

FAQs
The device is designed for base mounting with screw terminals and a 50 mm terminal width. Install the unit in a suitable panel, connect input and output terminals per the operating diagram, and secure the connections to 50–75 N·m. Ensure the fourth pole is positioned as specified (Right Side) and that the switch is front-operated for easy manual transfer during commissioning and routine maintenance.
Key specs include a 1250 A current rating, rated operational currents for AC-23A across 380–415 V, 500 V, and 690 V, 1000 V rated insulation voltage, 12 kV rated impulse withstand, IP20 front protection, and 50–75 N·m tightening torque on screw terminals. The device uses four poles with a base-mounting design and Front operated actuation for accessible switching.
Yes. The switch is rated for high-current operation in voltages up to 415 V (AC-23A and AC-22A), and it supports industrial power distribution needs. Its insulation rating of 1000 V and impulse withstand of 12 kV provide ample protection for typical distribution center feeders, while the IP20 front enclosure helps protect internal components in controlled environments.
The product carries a CE Declaration of Conformity, RoHS information, and Reach declarations, along with a DNV Certificate for specific safety standards. These certifications support regulatory compliance, traceability, and responsible procurement in sensitive industries like marine, energy, and critical facility power systems.
The design minimizes maintenance through robust screw-terminal connections and a reliable 1250 A 4P switch configuration, reducing retightening needs and fault occurrences. The option to order the handle and shaft separately allows ergonomic customization, improving operator acceptance. Overall, lower downtime, faster commissioning, and long-term reliability drive favorable total cost of ownership in critical power transfer applications.
