OTL-PEN50 connector yellow/green/blue 2xAl/Cu 1.5-50mm² 1000V AC/1500V DC Connector, universal terminal MAA2050P10

Universal connector for splitting the PEN conductor into N and PE

The universal OTL-PEN50 connector is an advanced electrical accessory designed specifically for the safe splitting of the PEN neutral-protective conductor into separate neutral (N) and protective (PE) conductors in TN-C-S systems. It provides a reliable solution for both the modernization of existing installations and the construction of new electrical networks.

Construction and materials ensuring durability

The connector body is made of high-quality PA66 thermoplastic, which is characterized by exceptional resistance to high temperatures and a UL94 V0 flammability rating. The conductive elements consist of tin-plated aluminum, which guarantees optimal electrical conductivity and resistance to galvanic corrosion in Al/Cu connections.

The compact design with dimensions of 49×43×30 mm allows for efficient use of space in distribution boards and control cabinets. The internal tiers are factory-bridged, eliminating the need for additional connecting elements and simplifying the installation process.

Versatility of connections and compatibility

The connector supports a wide range of conductor cross-sections from 1,5 mm² to 50 mm², for both single-core and multi-core conductors made of aluminum or copper. Screw connections allow for secure fastening of various types of conductors without the need for special ferrule terminals.

The ClickSet™ mounting mechanism allows for quick and easy mounting on a standard TH-35 mm DIN rail. Alternatively, screw mounting is also possible, increasing application flexibility in various types of distribution boards.

Electrical parameters and operational safety

The device is characterized by high electrical parameters: the rated current is 320A for copper conductors and 290A for aluminum conductors, at a rated voltage of up to 1000V AC / 1500V DC. The operating temperature range from -25°C to +80°C ensures reliability in various environmental conditions.

The connector complies with the requirements of EN 60947-7-1:2009 and EN 61238:2003 standards, has short-circuit class A, and an IP20 protection rating. The yellow-green color for the protective part (PE) and blue for the neutral part (N) allows for unambiguous identification of the function of individual connections.

Application in TN-C installation modernization

The solution is particularly useful for modernizing older TN-C type installations to the modern TN-C-S system required by current safety standards. It enables the organization of the electrical installation in the distribution board by clearly marking the PEN conductor split point.

It is effective in residential, commercial, and industrial buildings where electrical installation safety is of crucial importance. The product is also available in larger cross-sections: 95 mm², 150 mm², and 240 mm² for higher power installations.

The universal OTL-PEN50 MOREK connector enables the safe conversion of power systems while maintaining the highest standards of quality and operational reliability.
