## Long description

Noark CH‑KA B 4A 6kA 3-pole miniature circuit breaker provides overcurrent protection for low-voltage distribution circuits. This compact three-pole device features a B‑characteristic thermal-magnetic trip curve and a rated current of 4 A with a breaking capacity of 6 kA, suitable for consumer units and industrial control panels. The product is intended for DIN‑rail mounting and offers reliable interruption of short-circuits and overloads while occupying minimal panel space.
Advantages
The three-pole design ensures simultaneous disconnection of all phases for safer maintenance and fault isolation. The B‑characteristic trip curve is optimized for protection of resistive and light inductive loads, providing prompt response to short-circuits while allowing temporary inrush currents from motors and lighting. Compact dimensions and DIN‑rail compatibility simplify installation in distribution boards and control cabinets. The device combines consistent mechanical construction with electrical performance suited for standardized electrical installations.
Suitable for
 Overcurrent protection in residential and commercial distribution boards
 Protection of three-phase lighting circuits and small motors
 Use in industrial control panels and machinery protection for low-power circuits
 Retrofit or new installations requiring compact DIN‑rail breakers
Key specifications
 Poles: 3-pole configuration for three-phase systems
 Trip characteristic: B‑curve thermal-magnetic release
 Rated current: 4 A
 Breaking capacity: 6 kA
 Mounting: DIN‑rail compatible housing
 Application voltage range: designed for low-voltage distribution (nominal system voltages)
How to use
Install the breaker on a standard DIN rail inside the distribution board or control panel, ensuring correct orientation and secure mechanical locking. Connect conductors to the input and output terminals sized appropriately for the rated current and the installation practice; tighten terminal screws to the manufacturer's recommended torque values. Verify correct three-phase wiring and perform continuity and insulation tests before energising. For commissioning, switch the breaker on and confirm it remains closed under normal load and trips under simulated fault conditions.
Lietošanas ieteikumi
Choose the breaker rating and characteristic consistent with the protected circuit and coordinate with upstream and downstream protection devices to ensure selectivity; perform periodic inspection and testing in accordance with local electrical standards.
