❓ Frequently Asked Questions

What does "C16" mean?

"C" is the tripping curve, suited for medium inrush loads like motors. "16" means 16 amp current rating.

Is this suitable for a three-phase system?

Yes. It protects all three phases with a single breaker.

Can this MCB be used in residential installations?

Usually found in commercial and industrial setups, but suitable for homes with 3-phase supply.

What’s the difference between B, C, and D curves?

B = 3–5× rated current, C = 5–10×, D = 10–20×. C is ideal for inductive loads.

Will this fit my enclosure?

Yes, it's designed for 35mm DIN rails, standard in most consumer and distribution boards. 3 Modules wide.
