OTL95-3 connector yellow-green 3xAl/Cu 6-95mm² 1000V AC/1500V DC, universal terminal MAA3095Y10

Universal busbar connector for Al/Cu conductors in power installations

The OTL95-3 busbar connector in yellow-green is a professional solution for the secure connection of aluminum and copper conductors with a cross-section of 6-95 mm². Designed for voltages of 1000V AC and 1500V DC, it is suitable for both industrial, photovoltaic, and power installations.

Construction and materials ensuring connection reliability

The body made of galvanized aluminum and polyamide PA66 guarantees corrosion resistance and electrical stability. The insulating material meets the UL94 V0 flammability class, ensuring maximum operational safety. The connector features internal bridged tiers, allowing for efficient power distribution between levels.

The universal screw connection mechanism enables the handling of various conductor types:

• Flexible conductors without ferrule end: 6-70 mm²
• Flexible conductors with ferrule end: 6-70 mm²
• Multi-core conductors: 6-95 mm²

Operating parameters and operational safety

The device operates in a temperature range from -25°C to +80°C, maintaining full functionality in harsh environmental conditions. The rated current is 490A, allowing for the transmission of significant power loads.

The structural dimensions are 59×84×51 mm (width×depth×height), and the weight is only 178g, which facilitates installation in switchboards with limited space. The tightening torque is adapted to the conductor cross-section:

• 12 Nm for 6-25 mm² conductors
• 22 Nm for 35-95 mm² conductors

Installation and installation compatibility

The mounting mechanism allows for quick fastening on a standard DIN rail TH-35 mm or alternatively using M6 (hex) screws. A single device provides 6 electrical connections on one level, simplifying the installation topology.

The IP20 protection rating protects against contact with live parts, and the yellow-green color identifies the grounding function according to international standards.

Regulatory compliance and quality certification

The connector meets the requirements of European standards:

• EN 60947 - low-voltage switchgear and controlgear
• EN 61238 - electrical connection equipment
• Quality certificates confirmed by notified bodies UL1059 and SGS FI

The design has achieved short-circuit class "A", which means it can be used as main power terminals in installations exposed to current overloads and short circuits.
