Samlex's MC4-2 Kit contains 1 male and 1 female MC4 solar panel connector. 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 when locked, the mating contacts are sealed against ingress of dust and

water. Speci cations are as follows:

• Connectors supplied with this kit are for use with wire size AWG #10 or AWG #12 with outer insulation

diameter of 3 – 6 mm

• 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, UL listed

Construction of MC4 Connectors (See Fig. 1)

The connectors can be crimped / soldered to wire size AWG #10 or AWG # 12 with an outer insulation

diameter of 3 to 6 mm.

MC4 Female Connector (PV-KBT4/6I) MC4 Male Connector (PV-KST4/6I)

Note: “Male” and “Female” designation is based on the mating characteristic

of the internal mating contact (see 2A and 2B)

Fig. 1. MC4 Male and Female Connectors

The Male and Female MC4 Connectors consist of the following components (See Fig. 1).

• Outer insulated housing with locking arrangement (1 of Fig. 1)

• Tin-plated Copper metallic male & female mating contacts (2A and 2B of Fig. 1). The wire is placed in

the crimping area (4 of Fig 1) and crimped with a special crimping tool

• Nut & internal rubber bush (3 of Fig. 1). When the nut is tightened, the internal rubber bush is

compressed around the outer jacket of the cable, providing water-tight sealing.
