Battery Modular Connectors (BMC)

Battery modular connectors (BMC) play a crucial role in establishing connections between batteries and power sources. They are especially essential in renewable energy power systems and generators, including solar power, wind power, hydropower, and hybrid systems. These systems rely on reliable battery connections that offer high conductivity and exceptional protection levels.

1-Pole BMC

Single-Pole BMC

The Single-Pole BMC Series is available in four housing sizes, each housing supports a range of contacts, with each contact supporting a specific amperage rating and standard wire size. The compact housing can be stacked vertically and/or horizontally with other Single-Pole BMC connectors of the same size.

2-Pole BMC

Double-Pole BMC

The Standard Double-Pole BMC connectors are designed with a robust one-piece thermal polycarbonate housing, incorporating stainless steel spring backplates. This construction ensures consistent “contact force” between mated contacts, resulting in low resistance and high electrical efficiency.

UL 1977 Certified

KST BMC has earned the prestigious UL 1977 certification for its ability to transmit high currents effectively. This certification ensures that these connectors meet rigorous safety and performance standards, providing reassurance and peace of mind to users.

1-Pole & 2-Pole Series

The KST BMC are available in two series: Single-Pole and Double-Pole. The number of poles refers to the separate circuits that a connector can support. A single 1-pole connector can accommodate one circuit, while a double 2-pole connector can handle two circuits simultaneously. Both series offer a wide range of current ratings, from 15 to 350 Amps, making them suitable for use with up to 600 Volts of continuous AC or DC operation.

Reliable & Efficient

With their versatility and robust design, KST BMC provides reliable and efficient connectivity solutions for diverse power systems, ensuring seamless power transmission and supporting the demanding requirements of renewable energy and generator applications.

APP Equivalency

KST’s BMCs offer comparable housing, a wide range of contacts, and support for AWG sizes, meeting diverse industry standards and requirements. They are the equivalent of industry-leading battery connectors, ensuring compatibility and versatility.
