30 A Terminal Block - 12 Circuits

The BLUE SEA 30A 12-circuit terminal block (reference 2512-BSS) is designed for distributing and organizing electrical connections on board vessels. It centralizes and secures multiple circuit connections, providing a structured solution for electrical installations.

This terminal block has a maximum capacity of 30 amperes per circuit. It is suitable for handling medium to high loads, typical of navigation equipment, lighting, or pumping systems.

This terminal block has 12 separate circuits, allowing clear separation of different power supplies.

No, this terminal block is a pure distribution solution. It does not include overcurrent protection. External protection devices, such as circuit breakers or fuses, must be added upstream for each circuit.

The dimensions of this terminal block are 196.8 mm in length, 42.8 mm in width, and 14.3 mm in height. These dimensions allow for installation in confined spaces.

This terminal block is suitable for use in 12V or 24V electrical systems, common on board vessels.

The terminal block mounting points are designed for #10 (M5) mounting screws.

The terminals of this terminal block are equipped with #8 (M4) screw-type termination, ensuring reliable conductor connection.

Yes, this terminal block is part of the Blue Sea Systems range, known for the robustness of its wiring solutions designed for marine environments. It is intended for use aboard vessels.

This terminal block provides an orderly connection interface for individual circuits before they are connected to a device or control panel. It complements the brand's bus bars, which are typically used to consolidate main ground or positive power points.

The terminals are designed for #8 (M4) termination screws. Ensure the wire cross-section is compatible with the screw size and can handle the maximum current of 30 amperes per circuit without overheating.

Although it is designed and optimized for marine applications, a terminal block is a generic electrical component. It could technically be used in other 12V or 24V systems if current specifications and environmental requirements are met.

The available information does not mention protective caps or a cover being included with the 2512-BSS terminal block. It is recommended to check for separately available accessories if additional protection is required.

With its 12 separate circuits, this terminal block allows you to centralize and clearly separate the different power feeds. It is recommended to group wires by function and route them neatly to the appropriate terminals for a clean, secure, and easy-to-maintain installation.

A distribution terminal block like the 2512-BSS is a passive connection point. It does not inherently manage polarity. Polarity (positive or negative) must be handled by the upstream and downstream wiring, according to the requirements of each connected circuit.

In a complex electrical system, this terminal block acts as an organized junction point. It distributes power from a main source (often via a bus bar) to multiple individual circuits while helping maintain wiring order and clarity.

This terminal block can be used interchangeably to distribute either the positive or the negative, or a mix of both if needed, provided the 30-ampere current capacity per circuit is not exceeded. It is designed as a neutral connection point for conductors.

The terminal block is a passive component and can be mounted in any orientation (horizontal, vertical, etc.) as long as access to the terminals for wiring and maintenance is provided, and #10 (M5) mounting screws are used for secure fastening.

Blue Sea Systems is a recognized manufacturer of marine electrical products. While specific standards are not listed in the provided information, products from this brand are generally designed to meet marine environment requirements and industry standards.

By centralizing and organizing the connections of 12 separate circuits, this terminal block greatly simplifies the identification of wires and circuits. This makes maintenance, modification, or troubleshooting operations easier by providing a clear and structured access point for each connection.
