Clipsal by Schneider Electric | MAX9 MAXBAR Comb Busbar 3P+N 13 Module | 100A 400V Top Feed
The Clipsal MX9B313 is a MAX9 MAXBAR top-feed comb busbar rated 100A at 400V, configured 3P+N across 13 modules of 18mm pitch. The MX9B313 carries three phases and neutral from the main switch across a row of Clipsal MAX9 three-phase protective devices, replacing the cable tails a traditional switchboard loom needs. It complies with AS/NZS 61439-3 and AS/NZS 3000, and ships as the kit without a neutral terminal block, with four connectors to bring the feed onto the bar.
Wiring a three-phase switchboard row by hand means running three phase tails and a neutral to every protective device, which takes installation time and crowds the enclosure. A row of three-phase devices multiplies the terminations an electrician has to make and complicates later fault finding. The MX9B313 addresses this with a top-feed comb busbar that distributes three phases and neutral in a single pass. Its cuttable configuration lets an electrician trim the bar to the exact module count a row requires.
MAXBAR is built to speed up switchboard assembly: Clipsal rates the system at up to 15 times faster than feeding devices with individual cables. The MX9B313 arrives as a kit with the four connectors and tooth covers a three-phase row needs, so there is less to source and less to hand-terminate. Feeding three phases and neutral from one comb gives a cleaner assembly that is quicker to verify and hand over. For contractors building three-phase MAX9 boards, the busbar keeps every switchboard consistent from job to job.
Features
- 100A rated — the MX9B313 carries up to 100A per phase across the bar, matching the main switch and device ratings used in MAX9 boards.
- 3P+N configuration — distributes three phases and neutral along the bar, feeding three-phase final sub-circuits without separate cable looming.
- 400V three-phase rated — rated 400V AC for three-phase distribution across a MAX9 switchboard row.
- 13 modules of 18mm pitch — spans a 13-way three-phase row, with a 9mm outgoer pitch that lines up with Clipsal MAX9 devices.
- Top-feed comb design — picks up three phases and neutral from the main switch and combs them down to each device in a single pass.
- Cuttable bar — trims to the exact number of modules a row uses, so one 13-module bar also suits shorter rows.
- Four connectors and tooth covers included — the MX9B313 kit ships with 4 connectors and 4 tooth covers to bring the feed on and insulate unused teeth.
- Insulated body — the busbar is insulated and rated to 500V, with a 4kV impulse withstand voltage for switchboard use.
- Horizontal top mounting — mounts horizontally along the top of the DIN row as a top-feed bar.
- 960 deg C fire resistance — the insulation carries a 960 deg C glow-wire rating for enclosure safety.
- Compliant to AS/NZS 61439-3 — meets AS/NZS 61439-3 and AS/NZS 3000 for low-voltage switchgear assemblies.
- No neutral terminal block — this kit ships without a neutral terminal block and takes its feed through the connectors, so it suits rows that do not carry the main incomer.
Where to use
- Three-phase MAX9 boards — the MX9B313 feeds three phases and neutral across a row of three-phase protective devices in a MAX9 enclosure.
- Three-phase device rows — lands the feed across a row of Clipsal MAX9 three-phase RCBOs and circuit protection on a 3P+N row.
- Switchboard upgrades — replaces cable-tail looming when building a three-phase row into a MAX9 enclosure.
- Larger domestic and commercial boards — suits installations that carry three-phase supply into a MAX9 switchboard.
- Rows without the main incomer — the MX9B313 is made for rows that take their feed through the connectors, not the row holding the main switch.
- Consistent board layouts — helps contractors standardise three-phase MAX9 switchboard builds across multiple jobs.
The MX9B313 is a three-phase busbar and is not for single-phase 1P+N rows, which require a 1P+N busbar. It ships without a neutral terminal block, so it is not for single-row boards or the row that carries the main incomer. It is a MAX9 system component for installation by a licensed electrician, and is not compatible with other busbar ranges or non-MAX9 enclosures.
