GEN3 MCB6-332 32A Three Pole C-Curve MCB Circuit Breaker 6kA

Description

Three-phase protection that trips together.

The GEN3 MCB6-332 is a 32-amp three-pole miniature circuit breaker with a C-curve tripping characteristic and 6kA breaking capacity. It mounts on standard DIN rail across three modules and protects all three phases of a three-phase circuit at once, with a common trip mechanism that isolates every phase together on a fault. The 32A rating is a common choice for larger three-phase loads such as motors, three-phase appliances and sub-mains.

Key Features

Why Three Poles and Common Trip Matter

On a three-phase circuit, a fault on any one phase needs to disconnect all three to keep the load and wiring safe. The MCB6-332's three poles share a common trip bar, so an overload or short circuit on a single phase trips the whole device, isolating the complete circuit at once. A C-curve characteristic tolerates the brief inrush of typical three-phase loads while still protecting against sustained overloads, and the 6kA breaking capacity suits most commercial and light industrial switchboards.

Flexible Terminals, Standard DIN Fit

Fork and tunnel terminals let the MCB6-332 connect to a busbar comb or directly to cable, making three-phase board assembly quick and tidy. Spanning three modules 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 a three-pole MCB like the MCB6-332 do?
A: It protects all three phases of a three-phase circuit and trips them together. A fault on any one phase isolates the whole circuit via a common trip mechanism.

Q: What does the C-curve and 6kA rating mean?
A: The C-curve trips between five and ten times rated current on short-circuit, tolerating normal inrush. The 6kA breaking capacity is the maximum fault current it can safely interrupt, suiting most commercial and light industrial installations.

Q: How much space does the MCB6-332 take in a switchboard?
A: It is a three-module device, approximately 55mm wide, and mounts on standard DIN rail in any compatible load centre or switchboard.
