Solution Series - bolt connection terminal blocks
Bolt connection terminal blocks, also known as stud-type or screw-type terminal blocks, are robust electrical connectors designed for high-current and high-voltage applications. These blocks feature a threaded stud or bolt that secures ring or fork terminals, providing a reliable and vibration-resistant connection. They are typically rated for currents from 100A to over 600A, with voltage ratings up to 1000V AC/DC, and are available in configurations such as 1-pole, 2-pole, or multi-pole assemblies. The bolt connection ensures low contact resistance and high mechanical strength, making them ideal for power distribution and heavy-duty industrial environments. Common materials include tin-plated copper or brass conductors with polyamide or thermoplastic insulation, offering high dielectric strength and flame retardancy (UL94 V-0). These blocks are often used in conjunction with busbars or as part of a modular terminal block system, allowing for easy expansion and maintenance.
These terminal blocks are primarily deployed in industrial control panels, power distribution boards, switchgear assemblies, and automation systems. They are essential in sectors such as manufacturing, energy generation, renewable energy (solar and wind), transportation (railways and marine), and heavy machinery. Typical applications include connecting power cables, transformers, motors, generators, and battery banks. They are also used in HVAC systems, elevators, and mining equipment where high current capacity and secure connections are critical. Their robust design makes them suitable for harsh environments with high vibration, temperature extremes, or exposure to dust and moisture, often meeting IP20 or higher protection ratings when enclosed.
Within the Solution Series, key subcategories include single-pole bolt terminal blocks (e.g., models like ER0208-01 for 100A, ER0208-02 for 200A), multi-pole blocks (e.g., ER0208-03 for 3-pole 300A), and feed-through blocks for busbar connections. The article codes typically follow a pattern: ER0208-XX, where XX indicates the current rating or pole configuration. For example, ER0208-04 might denote a 400A 1-pole block, while ER0208-05 could be a 2-pole 250A variant. These blocks often include accessories like marking tags, end covers, and mounting brackets, but the core articles focus on the terminal block itself. Other relevant items include high-current stud connectors and modular bolt blocks for DIN rail or panel mounting.
