GEN3 G45X2-20A 20A Double Pole RCBO Safety Switch 4.5kA Single Module

Description

True double-pole protection in a single module.

The GEN3 G45X2-20A is a 20-amp double-pole RCBO safety switch with a 4.5kA breaking capacity, combining residual-current (RCD) and overcurrent (MCB) protection in one compact device. Unlike a single-pole RCBO, it disconnects both the active and neutral conductors on a fault or overload, yet fits in a single 18mm module, leaving more room for wiring. Its 30mA Type A residual-current detection and dual-way wiring make it well suited to caravans, RVs, motorhomes and compact switchboards, with the 20A rating giving headroom for larger circuits and higher loads.

Why True Double-Pole Matters

A double-pole RCBO switches both the active and neutral conductors, fully isolating the protected circuit when it trips. This is particularly valued in caravans, RVs and motorhomes, where supply polarity cannot always be guaranteed, so isolating both conductors gives an added margin of safety. The G45X2-20A delivers this in a single 18mm module, where double-pole protection would traditionally take two module spaces, freeing room in compact boards. Its 20A rating suits larger circuits such as higher-draw appliances and combined loads.

RCD and MCB in One Device

As an RCBO, the G45X2-20A combines two protective functions: residual-current detection that trips on earth leakage at 30mA to protect against electric shock, and overcurrent protection that trips on overload and short circuit. The Type A classification detects both AC and pulsating DC residual currents. Dual-way wiring allows line or load connection at the top or bottom, and the unit is AS/NZS 61009.1 compliant.

Q: What does the GEN3 G45X2-20A protect against?
A: As an RCBO it provides both residual-current (earth leakage) protection at 30mA and overcurrent protection against overload and short circuit, in one device.

Q: What is the difference between the G45X2-20A and the lower-rated models?
A: Current rating. The G45X2-20A is rated 20A, against 16A and 10A versions. All are 4.5kA true double-pole RCBOs in a single 18mm module.

Q: Is the G45X2-20A suitable for a caravan or RV?
A: Yes. Its double-pole disconnection and compact single-module size make it well suited to caravans, RVs and motorhomes, where isolating both conductors adds safety.
