Rated at 60A and 600V, it features a screw-type connection structure, tinned copper conductive components and a durable thermosetting plastic housing.
With a wiring range of 6–14mm² and a compact body measuring 83.5 × 41.2 × 32.5mm, this terminal block is suitable for power distribution, electrical equipment and industrial wiring applications.
Its three independent connection positions help keep conductors properly arranged and provide a practical solution for stable electrical connections.
TC-603 3 Pole Fixed Terminal Block
The JINH TC-603 3 Pole Fixed Terminal Block is designed for electrical applications that require dependable wire connections, organized conductor arrangement and a practical terminal structure. With three independent connection positions, this model provides a convenient way to connect and distribute electrical conductors in power circuits, control equipment and general industrial installations.
Rated at 60A and 600V, the TC-603 is suitable for electrical systems operating within its specified ratings. Its screw-type connection design allows conductors to be secured through mechanical tightening, helping maintain stable contact between the wire and the conductive terminal. This structure is widely used in electrical equipment where reliable wire termination and straightforward installation are important.
Three Independent Connection Positions
The TC-603 features a three-position terminal layout. Each position provides a separate connection point, making it easier for installers to arrange conductors according to the wiring requirements of the equipment. Compared with a single connection point, the three-pole structure offers more flexibility when several electrical lines need to be connected within one compact component.
The fixed design helps keep the terminal block in its intended installation position. It can be incorporated into electrical assemblies and equipment wiring layouts where a stable, clearly arranged connection component is required. The screw terminals provide a familiar connection method for electricians and equipment manufacturers, making the product practical for different wiring projects.
Tinned Copper Conductive Components
Conductive components are made of tinned copper. Copper is commonly selected for electrical terminals because of its conductivity, while the tin-plated surface provides a protective finish for the metal. This material combination is suitable for terminal applications where consistent electrical contact and dependable conductor connection are required.
The screw connection structure applies pressure to the inserted conductor when tightened. Correct wire preparation and tightening according to the installation requirements help establish a stable electrical connection. The TC-603 supports multi-stranded flexible cords, single-strand hard wires and multi-stranded hard wires, as indicated in the product specification image.
Thermosetting Plastic Housing
The terminal block uses a thermosetting plastic housing. This material is commonly used in electrical connection components because it maintains a firm molded structure and is suitable for use in electrical assemblies. The housing supports the internal conductive parts and helps keep the three connection positions arranged within one component.
The dark housing and transparent protective cover allow the terminal structure to remain compact and organized. The cover also provides a physical barrier over the connection area. During installation and maintenance, users should follow the relevant equipment instructions and ensure that the power supply is disconnected before handling the terminal block.
60A Rated Current and 600V Rated Voltage
The TC-603 has a rated current of 60A and a rated voltage of 600V. These ratings make it suitable for selected power connection and distribution applications, provided that the complete electrical system is designed within the product's specified limits.
The wiring range is 6–14mm², offering compatibility with conductors within this specified cross-sectional range. Selecting the correct wire size is important for connection quality and electrical safety. Users should confirm conductor type, wire cross-section, operating current and installation conditions before choosing the terminal block for a particular project.
Compact Dimensions for Equipment Installation
The overall dimensions of the TC-603 are 83.5mm in length, 41.2mm in width and 32.5mm in height. Its three-pole structure combines multiple connection positions in one component, helping equipment manufacturers arrange wiring in a more orderly way.
The compact terminal design can be used in electrical control assemblies, power distribution equipment, machinery wiring and other installations that require fixed wire connection points. Before installation, users should check the available mounting space and confirm that the product dimensions match the equipment layout.
Typical Applications
The JINH TC-603 can be considered for a range of electrical connection applications, including:
Power distribution equipment
Industrial electrical control assemblies
Machinery and equipment wiring
Electrical cabinets and control panels
Power connection and conductor distribution
General electrical installation projects
The appropriate application depends on the system design, conductor selection, environmental conditions and applicable electrical standards. Users should verify that the terminal block's ratings and installation requirements match the intended operating conditions.
