With a neutral tail, compact footprint, and robust safety performance, it’s the ideal choice for electricians and contractors working in commercial, industrial, and switchboard environments where both safety and ease of installation are essential.

Q: Does this RCBO protect the neutral conductor?
A: No, the neutral is not protected, but a neutral tail is provided for connection convenience.

Q: Can this be used in standard commercial switchboards?
A: Yes, it is fully DIN mountable and complies with AS/NZS 61009 standards for commercial installations.

Q: What type of loads is the C Curve suited for?
A: C Curve is ideal for resistive and moderately inductive loads, including lighting and motor loads.

Q: Is this RCBO suitable for residential use?
A: While primarily designed for commercial/industrial use, it can also be used in residential three-phase circuits where applicable.
