Frequently Asked Questions (FAQ)
Q1: Why choose brass neutral links over aluminum or copper?
Brass neutral links offer the optimal balance of conductivity, mechanical strength, and cost-effectiveness. While copper has higher conductivity, brass provides better spring properties, superior corrosion resistance, and excellent machinability. Compared to aluminum, brass offers higher strength, better contact properties, and eliminates galvanic corrosion issues with copper conductors.
Q2: What is the purpose of tin plating on brass neutral links?
Tin plating provides multiple critical benefits: prevents surface oxidation maintaining low contact resistance, enhances corrosion protection particularly in humid environments, improves solderability for special applications, and provides better contact surface for aluminum conductors reducing galvanic corrosion risk.
Q3: Can you manufacture custom neutral link configurations?
Yes, we specialize in custom neutral link solutions including special pole arrangements (asymmetric spacing), custom current ratings, unique mounting configurations, integrated monitoring (CT mounting points), special markings/color coding, and OEM branding. Our engineering team can develop optimized solutions for your specific application requirements.
Q4: What testing is performed on your brass neutral links?
Every production batch undergoes comprehensive testing including dimensional verification, conductivity testing, temperature rise testing at 1.5x rated current, pull-out force testing of termination screws, salt spray corrosion testing (500+ hours), dielectric strength verification, and short-circuit withstand testing where applicable.
Q5: How do I select the correct neutral link for my application?
Selection depends on four key factors: system current requirements (continuous and peak), number of circuits to be connected, installation method (DIN rail or direct mount), and environmental conditions (humidity, temperature, corrosive atmosphere). Our technical team can assist with proper selection based on your specific application parameters.
