MSS International, through its specialist division G Corner Electrical Systems, offers advanced DC switches and isolators designed to meet the highest standards of safety, efficiency, and durability.
EnquiryEngineered for Versatility and Performance in Diverse Applications
DC switches and isolators are indispensable components of modern electrical systems. These devices ensure safety during maintenance and fault resolution by isolating circuits, while their robust design supports demanding industrial applications. MSS International’s range combines cutting-edge materials, advanced manufacturing, and bespoke designs to deliver unmatched reliability.
- DC Breakers for On-Load Switching: MSS DC breakers allow circuits to be opened or closed under load, providing continuous power flow while protecting against overloads. This makes them essential in applications like electrolytic cell isolation, where maintaining power integrity is critical.
- DC Isolators for Off-Load Circuit Safety: Designed for no-load operations, MSS DC isolators provide a visible isolation gap to ensure complete disconnection before any circuit work begins. These devices excel in environments requiring strict safety protocols, such as battery systems or photovoltaic arrays.
- Tailored Designs for Industry-Specific Needs: Whether for chlorine refineries, Green Hydrogen production, or metals refining, our DC switches and isolators are customised to suit specific operational requirements. With encapsulated contacts for harsh environments and portable models for flexible use, MSS offers solutions tailored to each customer’s needs.
- Seamless Integration and Turnkey Support: From initial design validation to modular assembly and site delivery, MSS ensures that every product integrates seamlessly into your system. Our modular packaging streamlines installation even in remote locations, while our on-site specialists provide supervision and final commissioning support.
MSS International’s DC switches and isolators combine precision engineering with industry expertise, ensuring reliable performance in the most challenging conditions.

01 / FAQs
What is the difference between a DC switch and a DC isolator?
A DC switch can operate under load, opening or closing a circuit while maintaining current flow. A DC isolator, by contrast, operates off-load, providing a visible disconnection point for maintenance or safety purposes.
Can MSS customise DC switches and isolators?
Yes, MSS offers fully customised designs to meet specific voltage, current, and environmental requirements, including harsh industrial settings.
How does MSS ensure product quality?
Every switch and isolator undergoes rigorous testing, including contact resistance analysis, torque checks, and voltage endurance tests, ensuring zero-defect performance.
How to install a DC breaker or Isolator?
The G Corner Team is composed of installation specialist going directly to your site. We provide a dedicated support in the installation, in addition to all working instructions for you to safely operate in the future.
What current flows through a DC isolator?
The current that flows through a DC isolator depends on the specific application and the load it is designed to handle. Typically, DC isolators are rated for specific current capacities such as 10A, 20A, or higher, ensuring they can safely interrupt the circuit without damage. The exact rating should be chosen based on the operational requirements and safety standards of the installation.
What industries benefit from MSS DC switches and isolators?
Our solutions are widely used in chlorine refineries, photovoltaic systems, Green Hydrogen production, and metals refining.
What is the role of a DC breaker in a chlorine refinery?
A DC breaker in a chlorine refinery plays a critical role in ensuring electrical safety and operational reliability. It protects the electrical circuits by interrupting the flow of direct current in case of overloads or short circuits, thereby preventing damage to equipment and reducing the risk of fire or explosions in a highly reactive environment.
What support does MSS provide during installation?
MSS offers modular preassembled components, comprehensive installation guides, and on-site supervision by our specialists to ensure smooth and efficient installation.
