Clipsal MX9MC163R MAX9 MCB 1P 63A C Curve 6kA 240/415V Incomer Red Toggle

Description

Red-toggle 63A incomer for clear main-switch identification.

The Clipsal MX9MC163R is a 1-pole 63A miniature circuit-breaker from the MAX9 range, purpose-designated as an incomer and fitted with a distinctive red toggle so the main switch stands out instantly on a busy switchboard. It delivers a C-curve trip characteristic and 6kA breaking capacity, is rated 240/415V and built to AS/NZS 60898 — the same proven MAX9 breaker mechanism as the standard 63A, set apart by its incomer role and red handle.

Why it Matters

Designated as an Incomer
Unlike the standard 63A MCB, this variant carries Clipsal's incomer device designation — it's intended for use as the main switch feeding a distribution board. Its red toggle makes the main incomer immediately identifiable to anyone working on the board, which matters for safe isolation.

MAXBAR Compatible as Main Incomer
When used as the main incomer, this MCB is compatible with MAXBAR, so it can pick up and distribute the active feed across the board's RCBOs and AFDDs without individual cable connections — speeding up switchboard assembly.

Wire Sealing for Secured Circuits
At 40A and above, this MCB includes a through-hole for sealing by wire, letting you lock the device against unauthorised removal. It's also compatible with the A9A26970 padlocking device for OFF-position locking.

What makes the MX9MC163R different from the standard 63A MCB?
It shares the same 63A C-curve breaker mechanism but is designated as an incomer and fitted with a red toggle, so the main switch is easy to identify on the switchboard.

Is the MX9MC163R a single-pole breaker?
Yes. It is a 1-pole (1P) MCB occupying a single 18mm module on the DIN rail, protecting one active conductor.

What is the breaking capacity of the MX9MC163R?
It has a rated short-circuit breaking capacity of 6000A (6kA), tested to AS/NZS 60898 for use in residential and commercial switchboards.
