GENERAL INFORMATION ON AN MC4 CONNECTOR SYSTEM
MC4 Connector Systems used to connect Samlex Solar Panels consist of male and female MC4 connectors and
branch connectors. This type of connector system is easy to install and uses "snap-in" safety locking tabs to
lock two mating connectors, thereby avoiding unintentional disconnection. Also, the mating contacts are
sealed against an ingress of dust and water. Specifications are as follows:
• Contact diameter Ø 4 mm
• Maximum rated current - 30 A
• Maximum system voltage - 1000 V
• Degree of ingress protection when connected and properly locked - IP67
• Temperature range 40°C to +90°C
• TÜV Rheinland – type approved
MC4 Connectors (Fig. 1)
The MC4 Connectors and branch connectors mentioned in this manual have been designated "Male" and
"Female" based on the characteristics of the mating contact inserts inside the terminals.
In the MC4 Male Connector (1 of Fig. 1), the internal mating contact insert (2, Fig. 1) is a male pin. It has
two slots (3 of Fig. 1) for insertion of the two "snap-in" type of locking tabs (6 of Fig. 1) of the MC4 Female
Connector (4 of Fig. 1) for firm mating connection. This connector is marked "-".
In MC4 Female Connector (4, of Fig. 1), the internal mating contact insert (5 of Fig. 1) is a female cylindrical
socket. It has two "snap-in" type of locking tabs (6 of Fig. 1) that are inserted into the two slots (3 of Fig. 1) in
the MC4 Male Connector (1 of Fig. 1) for firm mating connection.
Wire is crimped to the contact inserts (2 and 5 of Fig. 1) using a special purpose crimping tool designed for
MC4 connectors. After the wire has been crimped, the contact insert is required to be seated securely inside
the housing and the strain relief / seal (7 of Fig. 1) is to be tightened fully to provide a water-tight seal.
