Products

TYPLE supplies electrical protection and distribution products for solar PV systems, building power networks, energy storage installations, and electrical equipment. Our range covers circuit protection, surge protection, isolation, switching, power distribution, control, and connection. Customers can source individual electrical components or request integrated assemblies configured according to their system voltage, current, installation environment, and project requirements.

Combiner Boxes and Distribution Enclosures

Our range includes solar combiner boxes, PV isolator boxes, DC and AC combiner boxes, AC distribution boxes, battery protection boxes, and electrical junction boxes. These products bring protection and connection components together in an organized enclosure, helping simplify field wiring, inspection, and maintenance.

Available configurations can integrate gPV fuses, circuit breakers, isolator switches, surge protection devices, terminals, busbars, cable glands, and monitoring components. Input and output quantities, voltage ratings, enclosure materials, internal layouts, and component combinations can be selected for different solar, energy storage, and power distribution projects.

DC Protection Products for Solar PV Systems

TYPLE provides DC electrical protection products for photovoltaic arrays and energy storage circuits. The product range includes DC miniature circuit breakers, molded case circuit breakers, DC surge protection devices, PV isolator switches, DC fuses, fuse holders, solar connectors, and monitoring devices.

These components help protect cables and downstream equipment against overcurrent, short circuits, and transient overvoltage while providing circuit isolation for installation and maintenance. Products are available in different DC voltage classes, current ratings, pole configurations, and mounting methods. Selection should be based on PV string voltage, short-circuit current, inverter requirements, conductor capacity, and applicable project standards.

AC Circuit Protection and Power Distribution Products

Our AC-side product range supports final distribution, main power distribution, electrical control, and auxiliary power applications. Available products include MCBs, RCBOs, RCCBs, isolator switches, surge protection devices, overvoltage and undervoltage protectors, modular contactors, and low-voltage fuses.

For higher-current power distribution, TYPLE supplies molded case circuit breakers, air circuit breakers, automatic transfer switches, and disconnecting switches. The range also includes AC contactors, push buttons, indicator lights, limit switches, changeover switches, transformers, switching power supplies, voltage regulators, and terminal blocks.

How to Select Electrical Protection Products

Electrical protection and distribution products must be matched to the actual circuit design rather than selected by rated current alone. Important considerations include:

• Rated AC or DC operating voltage
• Load and maximum circuit current
• Prospective short-circuit current
• Required breaking capacity
• Number of poles
• Leakage protection requirements
• Surge protection type and rating
• Cable size and terminal capacity
• Installation and mounting method
• Indoor or outdoor enclosure rating
• Ambient temperature and environmental conditions

Outdoor PV systems generally require DC-rated components and weather-resistant enclosures. Building distribution systems may place greater emphasis on breaking capacity, residual-current protection, transfer control, and DIN-rail installation.

OEM Electrical Products and Custom Assemblies

TYPLE offers OEM and project-based customization for customers requiring specific ratings, component combinations, enclosure sizes, wiring layouts, labels, colors, or packaging. Combiner boxes and distribution assemblies can be supplied pre-wired according to a confirmed electrical design. Individual protection and control devices can also be configured for private-label distribution and bulk project procurement.

Customers can provide circuit diagrams, voltage and current requirements, equipment models, cable specifications, installation conditions, and order quantities. Based on this information, TYPLE can recommend suitable components and confirm the required protection and distribution configuration.
