Crabtree TOPAZ 2P Isolator 4x4

• Primary Function & Application: An essential high-power safety device, this complete 2P (Double Pole) Isolator Switch is engineered to provide a safe and compliant point of local isolation for heavy-duty fixed appliances. It ensures complete de-energisation by disconnecting both the live and neutral connections, which is critical for safe maintenance, repair, or emergency shutdown.
• Architectural Design Statement: Presented in a bold, square 4x4 (100mm x 100mm) format, this isolator moves beyond pure function to become a design element. It perfectly complements modern interiors, offering a balanced, symmetrical aesthetic that aligns with other 4x4 sockets in the TOPAZ range.
• Versatile Amperage Options: Available in two distinct ratings to meet specific appliance requirements: a 30 Amp version for standard geysers and ovens, and a heavy-duty 60 Amp version for large stoves, hobs, and powerful fixed machinery.
• Elegant TOPAZ Aesthetic: Features the signature ultra-slim, screwless coverplate and a large, clearly marked recessed switch lever. This allows a critical safety component to integrate flawlessly into a high-end, minimalist design scheme.
• Dual Colour Variants: Available in two distinct finishes to match any interior: a timeless Classic White and a bold Black Graphite.
• Uncompromised Safety & Quality: Proudly manufactured in South Africa, this SABS-approved isolator is constructed from high-impact, UV-stabilised polycarbonate. It is engineered for exceptional safety and durability and is backed by a comprehensive 5-year warranty for complete peace of mind.

Features

• Complete 4x4 Unit: Supplied fully assembled with a 100mm x 100mm coverplate, yoke, and a high-power isolator module.
• Double Pole (2P) Switching: Safely disconnects both the Live and Neutral conductors simultaneously for complete and total circuit isolation, as required by law for fixed appliances.
• Multiple Current Ratings: Available in a 30A version and a 60A version to cater to a wide range of high-load fixed appliances.
• Clear ON/OFF Indication: Features a large, robust switch lever that is clearly marked for unambiguous visual confirmation of the power status.
• Dual Colour Options: Available in classic White and sophisticated Black Graphite across both amperage ratings.
• Durable Polycarbonate Construction: Manufactured from high-impact, UV-stabilised polycarbonate for exceptional durability and colour fastness.
• Slim, Screwless Profile: The modern, slimline design conceals all mounting screws, allowing a critical safety device to maintain a high-end aesthetic.
• SABS Approved: Fully compliant with South African National Standards (SANS 10142-1), ensuring the highest levels of safety and quality.
• 5-Year Warranty: Backed by a comprehensive 5-year manufacturer's warranty for complete peace of mind.

Benefits

• Maximum Electrical Safety: The double pole mechanism ensures the appliance is completely "dead" when switched off, protecting technicians during maintenance and users in fault conditions.
• Bold Architectural Statement: The 4x4 format elevates the isolator from a simple utility item to a deliberate design choice that enhances modern spaces.
• Regulatory Compliance: Installation of a local isolator is a mandatory legal requirement for all fixed appliances in South Africa, ensuring your installation is fully compliant.
• Aesthetic Cohesion: Allows you to maintain a consistent design language throughout a property, as your 4x4 isolators will perfectly match your TOPAZ 4x4 sockets.
• Convenient Emergency Control: Provides a quickly accessible means to shut off power to a specific high-load appliance in an emergency, without needing to access the main distribution board.
• Exceptional Durability: The robust polycarbonate construction and heavy-duty internal components are built to handle high electrical loads reliably for years.
• Guaranteed Peace of Mind: SABS certification and a 5-year warranty provide the ultimate assurance of safety, quality, and long-term reliability.

In-Depth Technical Specifications

Ideal Use

The selection of the correct amperage is critical and depends entirely on the power draw of the appliance being connected.

• 30A Isolator (15225/xxxP):
  • Standard residential geysers (hot water cylinders).
  • Most single-unit air conditioners.
  • Under-counter ovens and standalone hobs (check individual ratings).
  • Swimming pool pumps and borehole pumps.
• 60A Isolator (15226/xxxP):
  • Large, freestanding electric stoves with multiple plates and a large oven.
  • High-power instantaneous water heaters ("geyserless" systems).
  • Large central air conditioning units.
  • Can be used as a local isolator for small distribution boards or sub-circuits in outbuildings.

Tips

• CRITICAL - Mandatory Professional Installation: Isolators handle significant, potentially lethal electrical current. Installation must only be performed by a qualified and certified electrician who can ensure the correct wiring gauge and secure connections are used.
• CRITICAL - Match the Amperage: The most important step is to select an isolator with a current rating equal to or greater than the appliance it will control. Installing a 30A isolator on a circuit for a 45A stove is a severe violation and a major fire hazard. Always check the appliance's power rating plate.
• 4x4 Wall Box Required: This is a 4x4 unit and requires a square 100mm x 100mm wall box for installation. It is not compatible with rectangular 4x2 wall boxes.
• Understanding Double Pole Safety: A 2P isolator physically disconnects both the Live and Neutral wires. This is superior to a single-pole switch because it guarantees no part of the appliance's internal wiring can be live, even in the event of a wiring fault elsewhere in the building.
• Correct Wire Gauge: The electrician must use the correct thickness (cross-sectional area) of electrical wire that corresponds to the amperage (30A or 60A). Undersized wiring will overheat and can cause a fire.
• Secure Terminal Connections: High-current connections that are even slightly loose will generate extreme heat, melt the terminals, and create a serious fire risk. The installing electrician must ensure the terminal screws are torqued to the correct specification.
• Accessibility: Ensure the isolator is installed in a location that is easily accessible, as required by wiring regulations (e.g., within 1.5 meters of the appliance).
