GEN3 MCB6-163 63A Single Pole C-Curve MCB Circuit Breaker 6kA

Description

The top of the single-pole range.

The GEN3 MCB6-163 is a 63-amp single-pole miniature circuit breaker with a C-curve tripping characteristic and 6kA breaking capacity. It mounts on standard DIN rail in a single module width, protecting final subcircuits from overload and short-circuit faults in domestic, commercial and light industrial switchboards. At 63A it is the highest rating in the single-pole MCB6 range, suited to large sub-mains and high-demand feeds.

What the C-Curve and 6kA Mean

A C-curve breaker trips on sustained overloads and tolerates the brief inrush of typical mixed circuits, making it the common choice for general lighting, power and small motor loads. The 6kA breaking capacity is the maximum fault current the device can safely interrupt, which suits most domestic and light commercial switchboards fed from the distribution network.

Flexible Terminals, Single-Module Fit

Fork and tunnel terminals let the MCB6-163 connect to a busbar comb or directly to cable, making board assembly quick and tidy. At a single module wide it fits standard DIN rail in any compatible load centre or switchboard. As a GEN3 product it is covered by Australian/NZ approval or compliance certificates and is interchangeable with other major brands.

Q: What does the C-curve rating on the GEN3 MCB6-163 mean?
A: A C-curve breaker trips between five and ten times its rated current on short-circuit, tolerating normal inrush while protecting against sustained overloads. It suits general lighting, power and mixed loads.

Q: What does 6kA breaking capacity mean?
A: It is the maximum prospective short-circuit current the breaker can safely interrupt without damage, namely 6,000 amps. This is suitable for most domestic and light commercial installations.

Q: What circuits is the 63A MCB6-163 used for?
A: As the largest single-pole rating in the range, 63A commonly protects large sub-mains and high-demand feeds. Final circuit design should always be confirmed by a licensed electrician.
