Connector OTL150-2 grey 2xAl/Cu 25-150mm² 1000V AC/1500V DC, universal terminal MAA2150A10

Universal solution for Al/Cu installations in demanding applications

The OTL150-2 splice connector is a professional distribution component designed for installations requiring the highest reliability of electrical connections. Thanks to innovative galvanizing technology, it enables the direct connection of aluminum and copper conductors without the need for Cu/Al adapters or special bimetallic terminals.

Construction and materials ensuring operational safety

The housing is made of high-quality thermoplastic with a V0 flammability rating according to UL94, which guarantees the self-extinguishing properties of the material and maximum user safety. The compact design with dimensions of 51×54×84 mm allows for installation even in limited switchgear space.

The ClickSet™ mounting mechanism enables rapid fastening on a TH-35 mm DIN rail, significantly accelerating the installation process. Alternatively, screw mounting is also possible for greater application flexibility. Each connector features factory-applied contact paste, which protects the contact point from corrosion and ensures an optimal electrical connection immediately upon removal from the packaging.

Operating parameters and conductor compatibility

The universal nature of this connector is evident in the wide range of supported cross-sections - from 25 to 150 mm² for solid, stranded, and sector conductors. It can accommodate both rigid and multi-stranded conductors, eliminating the need to use different types of connectors in a single installation.

A rated voltage of up to 1000V AC/1500V DC makes this solution ideal for both low-voltage and medium-voltage installations. The operating temperature range from -25°C to +80°C ensures reliability in harsh environmental conditions.

Professional applications and certification

The OTL150-2 splice connector finds wide application in power engineering, industry, as well as residential and photovoltaic installations. It is particularly recommended for power distribution and as a main supply element in installations exposed to current overloads and short circuits.

The product meets the requirements of EN 60947 and EN 61238 standards and holds UL 1059 and SGS FI certificates confirming the highest manufacturing quality. Each unit undergoes rigorous mechanical, load, and short-circuit testing, resulting in achieving short-circuit class A according to IEC/EN 61238-1:2003.

Available in gray (IP20), it serves as an aesthetic element for any electrical switchgear while maintaining full technical functionality required in professional power engineering applications.
