Busbar Trunking Tap-Off / Plug-In Box

Engineered to tap power directly from a busbar trunking (busway) run, this fully sealed plug-in box houses an integrated molded-case circuit breaker behind color-coded copper busbar connections. The IP65-rated carbon steel enclosure, finished in RAL 7035 grey, is built to order — current rating, breaker selection, and connection interface configured to match your busway system as a B2B, OEM/ODM-ready platform.

Construction & Configuration

Every tap-off box is built around a sealed enclosure, color-coded busbar connections, and integrated circuit protection.

SEA

Fully Sealed Enclosure Structure

A sealed carbon steel enclosure keeps dust and moisture away from internal busbar connections and the circuit breaker.

TAP

Color-Coded Busbar Tap Connections

Yellow, green, and red copper busbar tabs provide clear three-phase connection points, with a blue tab for neutral/earth.

MCB

Integrated Molded-Case Circuit Breaker

A panel-mounted MCCB protects the downstream circuit fed from the tap-off connection.

OUT

Bottom Cable Entry

A bottom knockout/entry point routes outgoing cable to downstream distribution or equipment.

LCK

Locking Door with Warning Label

A latch-secured door with an electrical hazard warning label restricts access to qualified personnel.

FIN

Powder-Coated Carbon Steel Finish
