Onesto 20A 2P Isolator Module Only

• A heavy-duty, double-pole switch mechanism designed to provide safe and compliant isolation for fixed appliances up to 20A within the Onesto Oracle modular system.
• This is a module only; it is the functional internal switch and is not a complete, standalone isolator. It is a unique 'M' or Medium size and requires a specific grid plate.
• Engineered to provide 2-Pole (double pole) switching, simultaneously disconnecting both the Live and Neutral conductors for complete circuit isolation during maintenance.
• Allows electricians to build custom control panels that combine a 20A isolator with other standard modules, like an indicator light, for a fully integrated solution.
• Features a robust mechanism with silver cadmium oxide contacts for a long service life and reliable performance under high electrical loads.
• Backed by a comprehensive 5-year warranty, ensuring a safe and dependable safety switch at the heart of your custom assembly.

Features

• Function: Provides a 2-Pole (DP) latching switch action for the safe isolation of fixed appliances.
• Modular Design: A unique 'M' (Medium) size component of the Oracle system, designed to clip securely into a compatible Oracle grid plate.
• 20A Current Rating: Features a robust 20 Amp, 250V AC mechanism, ideal for appliances like air conditioners and pumps.
• Premium Contacts: Engineered with large, long-life Silver Cadmium Oxide (AgCdO) contacts for superior durability and resistance to electrical arcing.
• Durable Construction: Built with a high-quality, self-extinguishing polycarbonate body for safety and a long mechanical life.
• Core Colour Options: The module housing is available in White or Black Graphite to perfectly match the colour of the chosen grid plate.
• Certified and Compliant: Manufactured to meet the stringent safety and performance requirements of SANS 60669-1 for switches.

Benefits

• Compliant Appliance Safety: The primary benefit is enabling the creation of a legally compliant point of disconnection for fixed appliances, ensuring they are fully de-energised and safe to service.
• Flawless Design Cohesion: Allows you to build a heavy-duty isolator switch that perfectly matches the sophisticated design of your standard Oracle switches and sockets, eliminating industrial-looking safety switches.
• Ultimate Customisation: Enables the creation of unique control panels. For example, combine this isolator module with a Red Indicator Module in a single grid plate for a complete, professional geyser control station.
• Superior Durability: The use of Silver Cadmium Oxide contacts ensures the switch can handle the high electrical loads of motors and heating elements repeatedly without premature failure.
• Cost-Effective Repairs: In the event of a switch failure, only this module needs to be replaced, not the entire grid plate and surround assembly.

In-depth Technical Specifications

The Onesto 20A 2P Isolator Module Only is the heavy-duty heart of a custom Oracle safety switch. The following table details its complete technical specifications.

Ideal Use

This module is exclusively intended for professionals creating custom isolator switches for fixed appliances.

• Air Conditioning Units: Perfect for creating a compliant isolator for standard residential and light commercial air conditioners.
• Swimming Pool & Jacuzzi Pumps: Ideal for providing a safe and convenient point of disconnection for most standard-sized pump and filter systems.
• Electric Geysers / Water Heaters: Suitable for smaller geysers where the current draw does not exceed 20A.
• Fixed Heaters: Provides a safe isolation point for wall-mounted panel heaters or bathroom heaters.
• Any application where regulations require a 20A double-pole switch-disconnector for a permanently connected appliance.

Tips

To avoid purchasing errors and ensure a safe, compliant installation, it is critical to understand the specific nature of this module.

• CRITICAL - COMPONENT PART ONLY: You are purchasing only the internal 20A switch mechanism. To create a functional and finished product, you MUST also purchase a compatible Onesto Oracle Grid Plate and Surround separately.
• CRITICAL - UNIQUE 'M' MODULE SIZE: This is NOT a standard-size module. It is a Medium or 'M' size module, which is wider than a standard switch. It will NOT fit in a standard 1-lever grid plate (e.g., ON2011Y). You must use a specific grid plate designed to accommodate it.
• PROFESSIONAL INSTALLATION IS MANDATORY: The wiring of an isolator for a fixed appliance must be performed by a qualified and certified electrician in compliance with SANS 10142-1.
• EXAMPLE ASSEMBLY (20A Isolator with Indicator): To build this common configuration, you would need:
  1. An Onesto Grid Plate for 1x 'M' Module + 1x 'S' Module (e.g., ON201SY).
  2. This 20A Isolator Module (ONM2220).
  3. An Onesto Red Indicator Module (ONMIND).
  4. An Onesto 4x2 Decorative Surround.
• EXCLUSIVE COMPATIBILITY: This module is designed to fit ONLY in compatible Onesto Oracle grid plates. It is not compatible with other Onesto ranges or any other brand.
