3-pole OT Plus switch disconnectors provide solid isolation with a compact base/DIN mounting footprint, enabling quicker panel assembly and easier retrofits; this reduces installation time and post-installation adjustments in high-density control panels. The business impact is tangible: safer lockout/tagout procedures, fewer field-rework cycles, and consistent performance across multiple machines; typical applications include packaging lines, processing equipment, and automation cabinets where space remains at a premium. The screw-terminal design simplifies wiring, improves reliability, and supports both solid and stranded conductors within recommended ranges, minimizing wiring errors during maintenance. By offering a padlockable knob handle, these devices enhance operator safety and regulatory compliance during servicing, while external operation supports fast manual control in commissioning and troubleshooting. This combination delivers measurable efficiency gains, reduced downtime, and scalable integration with 3P protections in industrial environments. Compatibility with up to 4 NO and 4 NC auxiliary contacts broadens interlocking and signaling capabilities, enabling more sophisticated control logic without requiring additional modules. These attributes are particularly valuable in motor control centers and machine safety circuits where uptime matters and traceable maintenance records are essential.

FAQs
The 3P switch disconnectors are designed for base/DIN mounting and fit a 45 mm DIN cut-out. Use standard screw terminals for main circuit connections, following the recommended wire stripping length of 16-18 mm. Tightening torque is specified at 6 N·m per IEC 60947-1. For safety, use a Main Circuit Hexagon 4 screwdriver and ensure proper lockout-tagout with the padlockable knob handle during service.
Rated Operational Current AC-21A at 415 V is 160 A, and 125 A at 690 V, or 80 A at 800 V. The device supports a rated short-circuit capacity (I_cm) of up to 4.8 kA at 690 V and up to 50 kA at higher fuse configurations. Rated insulation voltage is 800 V, while the impulse withstand is 8 kV, making it suitable for demanding industrial environments.
Yes. The 3P front-operated OT Plus disconnectors are well-suited for motor control centers and interlock scenarios. They accommodate up to 4 NO and 4 NC auxiliary contacts, enabling complex safety interlocks and signaling. With front IP20 protection and IEC 60947-3 compliance, they provide reliable isolation and safe maintenance within control cabinets.
This device complies with IEC 60947-3 and carries CE conformity and UL/cULus certification, ensuring regulatory alignment for many markets. IP20 front protection supports indoor panel use, while the 3-pole design and robust construction help meet safety and reliability requirements across automated facilities.
The unit features robust mechanical durability rated at up to 100000 operations, reducing replacement frequency in active line environments. Screw terminals ease re-wiring during routine maintenance, and the padlockable handle supports safe lockout during servicing. Combined with modular compatibility for auxiliary contacts, this architecture lowers downtime and OPEX while simplifying spare-parts planning.
