300A Rectangular Terminal Post
Engineered for harsh industrial and automotive environments, the Longyyd 300A Rectangular Terminal Post delivers exceptional electrical conductivity and environmental protection. Featuring a ruggedized IP67-rated enclosure with a flip-open protective cover, this power stud ensures dust-free and water-resistant performance, making it ideal for electric vehicle (EV) battery arrays, commercial solar inverters, and industrial power distribution units.
Key Features & Advantages
- Polarity Identification: Vivid Red (Positive) and Black (Negative) options prevent wiring errors during high-voltage assemblies.
- Superior Dielectric Strength: Tested to withstand ≥3000VAC/min, ensuring zero insulation breakdown under high-voltage surges.
- Thermal Resilience: Wide operational temperature range from -40°C to 105°C, perfect for high-load engine bays or outdoor energy storage enclosures.
- Anti-Vibration & Anti-Corrosion: Full-copper/brass core minimizes contact resistance and heat generation, paired with stainless steel bolts and lock washers for robust mechanical lock.

FAQ Section
Q1: Does the terminal post come as a pair or individual units?
A: We supply them both as individual units and as color-coded pairs (1x Red Positive, 1x Black Negative). You can specify your required quantity and color configuration during the RFQ process.
Q2: What type of cable lug or connection is recommended for the M10 internal thread?
A: The terminal core features an internal M10 thread combined with a ∅10mm horizontal through-hole. You can secure connections using standard M10 metric machine screws, heavy-duty compression ring lugs, or pass a solid pin connector directly through the cross hole for flexible high-current routing.
Q3: How does the product achieve its IP67 waterproof rating?
A: Each terminal kit includes a custom-engineered high-density rubber sealing gasket that sits beneath the 43x43mm rectangular base flange, blocking moisture from penetrating the panel cut-out. Additionally, the tight-fitting protective polymer cap seals the top conducting elements from water splashes and dust ingress.
Q4: Is the housing material safe against fire hazards?
A: Yes. The outer protective cap and base insulating housing are manufactured from premium thermoplastic that meets the UL94-V0 flammability rating. In the event of extreme overheating, the material self-extinguishes within 10 seconds and does not drop flaming particles.
Q5: Can I request custom modifications or OEM branding for bulk orders?
A: Absolutely. As a direct manufacturer, we offer custom thread sizing (e.g., M8 or imperial threads), customized base dimensions, and laser-etched logo branding for wholesale commercial contracts. Please contact our sales team with your detailed blueprints.
