GEN3 MCB6-120 20A Single Pole C-Curve MCB Circuit Breaker 6kA

Description

Protection for power and appliance circuits.

The GEN3 MCB6-120 is a 20-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. The 20A rating is a common choice for power circuits and dedicated appliance feeds such as ovens and air conditioners.

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 MCB6-120 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 MCB6-120 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 20A MCB6-120 used for?
A: The 20A rating commonly protects power circuits and dedicated appliance feeds such as ovens and air conditioners. Final circuit design should always be confirmed by a licensed electrician.
