Onesto Isolator 60A 3P 4x4

• Provides the highest level of local electrical isolation for heavy-duty, three-phase fixed appliances requiring up to 60 Amps.
• Functions as an essential and legally required safety device, engineered with a triple pole (3P) mechanism that simultaneously disconnects all three live conductors.
• Masterfully combines mandatory SANS-compliant safety for high-current, three-phase systems with the sophisticated, modern aesthetic of the Onesto Oracle range.
• Delivered as a complete, ready-to-install 4x4 unit, providing a stylish and elegant alternative to bulky, industrial isolators in visible areas.
• Features a distinctive red switch lever for clear, unambiguous indication of the ON/OFF status, enhancing operational safety.
• Constructed from premium, high-impact polycarbonate to ensure exceptional durability and long-lasting performance in demanding environments.

Features

• Triple Pole Safety Mechanism: The core safety feature for three-phase equipment. It ensures a complete and verifiable disconnection of all three phases (L1, L2, L3) from the appliance, providing absolute safety for maintenance.
• Heavy-Duty 60 Amp Rating: A powerful rating designed to safely manage the significant electrical loads of large residential, commercial, and light industrial three-phase appliances.
• Standard 4x4 Footprint: Designed to be installed into a standard 4x4 (100mm x 100mm) electrical wall box.
• Clear Status Indication: The prominent red switch lever is clearly marked with "ON" and "OFF" for immediate visual confirmation of the circuit's state.
• All-in-One Integrated Unit: Supplied as a complete, pre-assembled product including the 4x4 faceplate, high-current 60A 3-pole mechanism, and robust mounting frame.
• Slim Wall Profile: Features the signature sleek, low-profile design of the Oracle range, allowing this heavy-duty device to match the aesthetic of standard switches.
• High-Impact Polycarbonate Housing: The entire unit is manufactured from tough, UV-stabilised polycarbonate to resist physical impacts and prevent colour degradation.
• Dual Colour Options: Available in a classic, clean White and a modern, sophisticated Black Graphite to complement any interior design.

Benefits

• Absolute Safety for Heavy-Duty Equipment: Provides the ultimate protection for technicians and property owners by creating a complete air gap in the three-phase supply during servicing of high-power equipment.
• Ensures Full Legal & Regulatory Compliance: Installing a correctly rated 3-pole isolator is a mandatory requirement of SANS 10142-1 for all three-phase fixed appliances, ensuring your installation is safe, legal, and insurable.
• Maintains a High-End Aesthetic: Allows you to meet critical safety regulations without compromising on interior design. Its elegant form integrates seamlessly into modern commercial kitchens, plant rooms, and workshops.
• Simplified Installation: The complete, all-in-one design is faster and easier for a qualified electrician to install compared to sourcing and fitting separate industrial components.
• Exceptional Durability: The high-quality materials are built to withstand the demands of both residential and commercial environments, ensuring long-term reliability.
• Creates a Cohesive Design Language: Guarantees a consistent, modern look across your entire installation by matching the design of the standard Oracle switches and sockets.

In-Depth Technical Specifications

This heavy-duty isolator is a critical safety component for any installation with high-current, three-phase appliances. Below are its detailed technical specifications.

Product Specifications

Ideal Use

A 60A 3-pole isolator is a specialized safety device for high-power, three-phase electrical appliances and systems.

• Large Commercial Stoves & Ovens: The primary application for isolating heavy-duty cooking equipment in restaurants, hotels, and catering facilities.
• Large HVAC Systems: Essential for safely isolating powerful three-phase air conditioning compressors or heating units in commercial buildings.
• Three-Phase Instantaneous Water Heaters: Required for high-capacity, industrial-scale tankless geysers.
• Large Three-Phase Motors: Provides local isolation for powerful motors used in workshops, for large pool pumps, or in light industrial applications.
• Sub-Distribution Board Isolation: Can be used as a local main switch or isolator for a small sub-DB in a workshop, outbuilding, or specific commercial area.

Tips

• FOR THREE-PHASE SYSTEMS ONLY: This is a critical point. This isolator is specifically designed for properties with a three-phase electrical supply. It is not suitable for and must not be used on standard single-phase systems found in most homes.
• 2-Pole vs. 3-Pole Distinction: For standard single-phase appliances (like most residential stoves and geysers), you must use an Onesto 2 Pole Isolator. Using a 3-pole isolator on a single-phase appliance is incorrect, non-compliant, and unsafe.
• Professional Sizing is Crucial: The 60A rating is for heavy-duty applications. A qualified electrician must calculate the full load current of the appliance to select the correctly rated isolator and its corresponding circuit breaker.
• Requires a 4x4 Wall Box: This isolator is designed for a square 4x4 (100x100mm) wall box and will not fit in a smaller 4x2 box.
• Mandatory Professional Installation: Due to the extremely high energy levels, the complexity of three-phase wiring, and the critical safety function of this device, it must be installed by a qualified and certified electrician with proven experience in three-phase systems.
