Clipsal MAX9 Miniature Circuit-Breaker (MCB) 3-Pole 63A C-Curve 6kA 415V Incomer Red Toggle

Description

Three-pole 63A main incomer MCB with red toggle for clear switchboard identification.

The Clipsal MX9MC363R is the dedicated incomer variant of the MAX9 3-pole 63A miniature circuit-breaker, featuring a distinctive red toggle that makes main switch identification instant in any switchboard. Delivering a C-curve trip characteristic and 6kA breaking capacity at 415V AC, it provides reliable overload and short-circuit protection at the head of a three-phase board. Built to AS/NZS 60898 and backed by a 7-year Clipsal warranty.

Why it Matters

Red Toggle for Instant Main Switch Identification
In an Australian switchboard, the main switch must be immediately identifiable. The MX9MC363R's red toggle makes it visually distinct from downstream breakers at a glance, reducing confusion during maintenance or emergency shutdown. This is the dedicated incomer variant — specifically designed for use as the main switch at the head of a MAX9 distribution board.

Wire Sealing for Secured Circuits
As a 63A device, this MCB includes a through-hole for sealing by wire, letting you lock the device against unauthorised removal — useful where a main incomer needs to stay verifiably in place. It's also compatible with the A9A26970 padlocking device for OFF-position locking.

Built Tough and Built to Last
Rated to 20,000 mechanical and 10,000 electrical operations, with an operating range of -25°C to 70°C (derating applies), the MX9MC363R is made for the temperature swings of real Australian switchboards. Limitation class 3 keeps let-through energy down during a fault, protecting downstream cabling.

What makes the MX9MC363R different from the MX9MC363?
The MX9MC363R is the incomer variant with a red toggle handle for clear main switch identification. It shares the same 63A, 3-pole, C-curve, 6kA electrical characteristics as the standard MX9MC363 but is designated for use as a main incomer rather than a general distribution sub-circuit breaker.

Can the MX9MC363R be used as a main switch?
Yes. It is designed specifically as a three-phase main incomer MCB. The red toggle provides instant visual identification as the main switch, and its suitability-for-isolation rating confirms it can serve as a disconnection device.

What is the breaking capacity of the MX9MC363R?
It has a rated short-circuit breaking capacity of 6000A (6kA) Icn at 415V AC, tested to AS/NZS 60898 for use in residential and commercial switchboards.
