The NHP MOD6+ 1 Pole C Curve MCB (MD6M1) offers dependable protection in a compact form, making it a go-to solution for electricians and installers seeking performance, safety, and compliance with Australian standards.

Q: What does a C Curve trip characteristic mean?
A: C Curve MCBs trip at 5–10 times their rated current, ideal for resistive loads and low inrush inductive circuits.

Q: Can this MCB be used in outdoor applications?
A: The unit itself is IP40, so it must be installed within a weatherproof enclosure if used outdoors.

Q: Is this breaker compatible with standard DIN rail systems?
A: Yes, the MOD6+ is DIN rail mountable and fits standard switchboards.

Q: Is this breaker suitable for three-phase systems?
A: No, this is a single-pole device. For three-phase circuits, consider using multi-pole versions of the MOD6+ series.

All products must be installed by a licensed electrican. DIY electrical work is illegal and very dangerous.
