Description

The WKC216B is a 16A 2 Pole 10kA Miniature Circuit Breaker (MCB) designed for dependable short-circuit and overload protection in small power and lighting applications. With a B-curve tripping characteristic and double-pole isolation, it’s ideal for heating circuits, immersion heaters, control gear, and general sockets where inrush currents remain low.

Each unit provides full isolation of both live conductors in line with BS EN 60898-1, making it suitable for domestic consumer units, commercial boards, and EV-ready installations.

Installer Tip: 16A B-curve breakers are commonly used for heating, immersion, and control circuits. For equipment with higher start-up currents, upgrade to a C-curve or D-curve version.

Key Features

  • 16A rated – suited to heating and small-power loads
  • 10kA breaking capacity – safe for higher-fault installations
  • 2-pole configuration – isolates both live conductors
  • B-curve tripping – fast disconnection for resistive or low inrush circuits
  • Bi-directional terminals – can be wired line or load from either end
  • Compact 36 mm (2-module) design – easy retrofit on any 35 mm DIN rail
  • Complies with IEC/EN 60898-1 and 18th Edition Wiring Regs
  • Suitable for consumer units, three-phase panels and EV boards

FAQs

What applications suit a 16 A B-curve MCB?

Commonly used for heating, immersion, and small-power sub-circuits where inrush current is minimal.

Is this breaker compliant with UK regs?

Yes – built to BS EN 60898-1 and compliant with the 18th Edition Wiring Regulations.

Can I use it in an EV board?

Yes – ideal for control or auxiliary feeds in EV consumer units.

Does it isolate both conductors?

Yes – 2-pole isolation disconnects both live lines simultaneously for added safety.
