Unlike low-current counterparts, it boasts a 600V/150A rating—making it suitable for large-scale power distribution—and an 8000V surge voltage resistance to withstand extreme electrical transients. Crafted with PA66 insulation (UL94 V-0) and M6 brass screws, it meets IEC standards for Material Group I and Pollution Degree 3, ensuring reliability in dusty, humid, or contaminated settings. With a wire range of 18–1/0 AWG (accommodating thick power cables) and a required stripping length of 16mm, the RKM-35 is engineered for heavy machinery, power cabinets, and renewable energy systems where safety and high-current handling are non-negotiable.
150A/600V Rating: Supports large current flows for heavy-duty applications (e.g., 3-phase motor drives, industrial heaters). The 600V rating makes it compatible with medium-voltage industrial power grids.
8000V Surge Protection: Resists extreme voltage spikes (e.g., from lightning or power grid faults), preventing damage to expensive equipment like frequency converters or generators.
Pollution Degree 3 Compliance: Designed to operate in environments with significant dust, smoke, or conductive particles (e.g., manufacturing plants, mining facilities). The PA66 insulation repels contaminants, reducing short-circuit risks.
Material Group I Classification: Meets strict IEC standards for electrical insulation, ensuring long-term performance even at maximum temperature and voltage.
M6 Brass Screws: Brass offers superior electrical conductivity and corrosion resistance compared to steel, making it ideal for high-current connections. The screws require 3.2–3.7N·m of torque for secure clamping.
Wide Wire Range: Accepts 18 AWG (signal wires) to 1/0 AWG (heavy power cables), eliminating the need for separate terminals for control and power circuits.
16mm Stripping Length Guidance: Precisely specifies how much wire insulation to remove, ensuring optimal contact with the brass terminal and minimizing resistance.
UL94 V-0 Flame Retardancy: PA66 insulation self-extinguishes within 10 seconds of removing a flame, preventing fire spread in case of electrical faults.
High-Temperature Stability: While not explicitly stated, its industrial-grade construction implies compatibility with high-heat environments (e.g., near furnaces or engines), though operating within -40℃ to 105℃ is recommended for longevity.
Manufacturing: Used in heavy machinery (e.g., CNC machines, hydraulic presses) and assembly lines. Its 150A rating handles the power demands of large motors, while Pollution Degree 3 compliance resists factory dust.
Power Distribution: Integrates into electrical cabinets, switchgear, and bus ducts for commercial buildings or industrial facilities. It distributes power from main panels to sub-circuits (e.g., lighting, machinery).
Renewable Energy: Suitable for solar inverters, wind turbine control systems, and battery energy storage (BESS) units. The 8000V surge protection shields against voltage fluctuations from solar panels or wind gusts.
Industrial heaters and ovens (e.g., 3-phase 480V heaters) that require high current.
Electric vehicle (EV) charging stations (fast-charging models) that handle 150A+ currents.
Marine and offshore systems (e.g., shipboard power distribution), where corrosion-resistant brass screws and durable insulation withstand saltwater environments.
Pollution Degree 3 refers to environments with "conductive pollution or dry non-conductive pollution that becomes conductive due to condensation." For the RKM-35, this means it can operate in dusty factories or humid warehouses without short-circuiting—critical for industrial reliability.
Yes, but it is overspecified for residential use. The RKM-35’s 600V/150A rating is designed for industrial systems; residential applications (typically 120V/20A) would benefit from a lower-current terminal block (e.g., EMD series) for cost and space efficiency.
A 16mm stripping length ensures the wire’s conductor makes full contact with the brass terminal, minimizing resistance and heat generation. Shorter lengths may cause poor contact, while longer lengths risk exposed conductors touching adjacent terminals.
Use 3.2–3.7N·m (approximately 28–32.7 lbf·in). Too little torque leads to loose connections; too much can strip the screw or crack the PA66 insulation. Always use a calibrated torque wrench.
No. Brass terminals are designed for copper wires. Aluminum wires oxidize over time, creating a high-resistance layer that can cause overheating. Use copper wires (18–1/0 AWG) for safe, long-term performance.
