The 4P 1250 A rating delivers high-current capacity for demanding applications, enabling a single switch to safely transfer large loads without voltage collapse. Business impact: reduced downtime and safer power transitions in critical processes. Application: data centers, water treatment, and large motor drives where uninterrupted operation matters. The padlockable 0-position and door interlock prevent unauthorized operation during maintenance, minimizing safety incidents and warranty concerns. Application: factory floors and switchgear assemblies where personnel safety is essential. The included handle and shaft support quick manual operation with a solid grip, reducing operator fatigue during frequent transfers. Business impact: faster change-overs and improved cycle times. Application: control panels with frequent source changes and interlocked safety procedures. Base mounting and screw-terminal wiring simplify installation, improving reliability and reducing assembly time. Application: panel builders seeking scalable, serviceable designs. Electrical performance specs: rated insulation voltage 1000 V, impulse withstand 12 kV, and short-time withstand current 50 kA for 1 s, delivering robust protection in fault events. This aligns with IEC 60947-1 and UL/CSA expectations for reliability and compliance. Environmental and compliance notes: RoHS and Reach declarations, Front IP20 protection, and 3rd-party documentation support traceability and regulatory alignment. These factors translate into lower lifecycle costs through easier maintenance planning, spare-part compatibility, and clearer installation guidelines.

FAQs
The unit uses base mounting with screw terminals, simplifying panel integration and wiring. The 50 mm terminal width supports straightforward, secure connections, reducing wiring errors during installation. This configuration is ideal for large control panels, minimizing assembly time and ensuring reliable fault-free operation in 1250 A circuits.
A 4-pole design ensures simultaneous switching of all conductors, reducing arcing and thermal stress during transfer. The 1250 A rating supports high-load applications, enabling smoother transitions with lower risk of nuisance tripping. This improves overall process uptime and reduces maintenance cycles in heavy machinery and distribution panels.
Yes, the switch is rated for a main circuit voltage of up to 1000 V, aligning with IEC 60947-1 expectations. The insulation voltage specification supports safe operation across the intended voltage range, while the 12 kV rated impulse withstand adds protection against transient overvoltages common in industrial environments.
The model carries a CE Declaration of Conformity for OT series switches and RoHS/Reach declarations for environmental compliance. This supports regulatory adherence in many markets, simplifies procurement documentation, and provides assurance during audits and quality reviews.
Plan for periodic inspection of the padlockable handle mechanism, door interlock integrity, and terminal torque (50–75 N·m per IEC 60947-1). The robust current rating and reliable interlocks reduce downtime during maintenance, lowering total cost of ownership through fewer unscheduled outages and longer service intervals for high-current transfer equipment.
