Description
The WKC316C 3 Pole 10kA MCB is a 16A C Curve breaker designed to protect three-phase circuits from short-circuit and overload faults. With a 10kA breaking capacity and compliance to BS 7671 (18th Edition), it’s commonly used for industrial loads, EV chargers, motors, and solar PV installs. Its C Curve tripping profile provides safe disconnection for circuits with moderate inrush currents.
Installer Tip: Choose C Curve devices for inductive loads where inrush occurs (motors, HVAC, EV). For resistive circuits, see the B Curve, or for heavy inrush, check the D Curve.
Key Features
- 16A rated current – protects medium three-phase inductive loads

Installation notes
Install in DIN rail consumer units or distribution boards. Select curve carefully:
- B Curve: resistive loads (lighting, sockets)
- C Curve: inductive loads (motors, HVAC, EV chargers)
- D Curve: heavy inrush loads (transformers, welders)
Confirm 10kA breaking capacity is sufficient for the site’s prospective fault level. Installation must comply with BS 7671 and be carried out by a qualified electrician.
FAQs
Where is the WKC316C best used?
In three-phase systems protecting 16A inductive loads such as EV chargers, motors, or HVAC equipment.
How does a C Curve compare with B and D?
C Curve trips at 5–10x In, designed for circuits with inrush. B Curve trips faster (3–5x In), while D Curve trips slower (10–20x In).
Why use a 10kA MCB?
It ensures the breaker can handle high prospective fault currents often found in commercial and industrial setups.
Is this breaker bi-directional?
Yes — it can be wired from either the top or bottom terminals.
Is it EV and PV compatible?
Yes — widely used in EV charge points and solar PV boards.
