Clipsal MX9MC216 MAX9 Miniature Circuit-Breaker MCB 2P 16A C Curve 6kA 415V

Description

Two-pole 16A protection with full double-pole isolation.

The Clipsal MX9MC216 is a 2-pole 16A miniature circuit-breaker from the MAX9 range, switching and protecting both conductors together for complete isolation of the circuit. It delivers a C-curve trip characteristic and 6kA breaking capacity, is rated 415V and built to AS/NZS 60898 — well suited to two-pole final sub-circuits in Australian distribution boards where both active and neutral (or two actives) need to be broken simultaneously.

Why it Matters

Double-Pole Isolation
As a 2-pole device, the MX9MC216 breaks both conductors of a circuit at once. That gives complete isolation when the breaker trips or is switched off — important for circuits where isolating just the active isn't enough, and a requirement in many two-pole and three-phase-derived configurations.

C-Curve for General Circuits
The C-curve trips between 5 and 10 times rated current, giving it the headroom to ride out normal inrush from mixed lighting and small-motor loads without nuisance tripping, while still clearing genuine faults quickly. It's the go-to characteristic for general-purpose final sub-circuits.

Suitable for Isolation
Clipsal rates this device as suitable for isolation, so it can serve as an isolating switch as well as an overcurrent protective device — useful where a circuit needs a clear, lockable disconnection point.

Is the MX9MC216 a two-pole breaker?
Yes. It is a 2-pole (2P) MCB occupying two 18mm modules (36mm total) on the DIN rail, protecting and switching two conductors together.

What does the C curve mean on this MCB?
C-curve means the breaker trips magnetically at 5 to 10 times its 16A rating, making it suitable for general circuits with moderate inrush such as lighting and power outlets.

What is the breaking capacity of the MX9MC216?
It has a rated short-circuit breaking capacity of 6000A (6kA), tested to AS/NZS 60898 for use in residential and commercial switchboards.
