The Niglon MCB6B1-10 10A Type B Miniature Circuit Breaker is a single-pole protective device designed to provide reliable overload and short-circuit protection for suitable domestic and light commercial electrical circuits.
Featuring a 10 Amp current rating, Type B tripping characteristic and 6kA breaking capacity, the MCB6B1-10 is suitable for appropriately designed low-current electrical circuits, including lighting and other installations where a 10A protective device is required.
Manufactured in accordance with BS EN 60898-1, this compact circuit breaker offers DIN rail mounting, bi-directional operation, a single-module width and terminals accepting conductors up to 25mm².
10A Type B Circuit Protection
The Niglon MCB6B1-10 has a rated current of 10A and a Type B tripping characteristic, providing overcurrent protection for suitably designed electrical circuits.
Type B miniature circuit breakers are commonly used where connected equipment has relatively low starting currents. Typical applications may include domestic lighting and other low-current circuits, subject to the cable size, load and installation design.
The breaker automatically disconnects the circuit when an overload or short-circuit fault causes it to trip, helping protect electrical wiring and connected equipment against the effects of excessive current.
Type B Tripping Characteristic
The Type B tripping characteristic provides instantaneous magnetic operation at approximately 3 to 5 times the rated current.
For a 10A Type B MCB, this corresponds to an instantaneous magnetic tripping range of approximately 30A to 50A.
The correct rating and tripping characteristic must always be selected to suit the connected load, cable protection requirements and circuit conditions.
6kA Short-Circuit Breaking Capacity
The MCB6B1-10 has a 6kA (6000A) rated short-circuit breaking capacity in accordance with BS EN 60898-1.
This rating indicates the maximum prospective short-circuit current that the device is designed to safely interrupt under its specified operating and test conditions.
The breaking capacity of the protective device must be suitable for the prospective fault current at the installation.
Single Pole DIN Rail Mounting
The Niglon MCB6B1-10 is a single-pole miniature circuit breaker designed for installation onto a compatible standard DIN rail.
Its compact single-module construction occupies approximately 18mm of DIN rail space, making it suitable for compatible consumer units and electrical distribution equipment.
The front-mounted operating lever allows the circuit to be manually switched on or off and reset following a trip, once the cause of the fault has been identified and corrected.
Bi-Directional Operation
Niglon specifies the MCB6B1-10 as bi-directional, allowing current to flow in either direction through the protective device within its approved operating conditions.
This provides additional flexibility for suitable electrical distribution arrangements, subject to the manufacturer's installation instructions and compatibility with the complete electrical system.
25mm² Maximum Cable Capacity
The Niglon MCB6B1-10 features screw terminal connections with a manufacturer-specified maximum cable capacity of 25mm².
The recommended terminal tightening torque is 2.5Nm, helping ensure secure electrical connections when installed using suitable conductors and the correct termination method.
Cable selection and termination must always comply with the manufacturer's instructions and the requirements of the electrical installation.
BS EN 60898-1 Compliant
The Niglon MCB6B1-10 is manufactured in accordance with BS EN 60898-1, the standard for circuit breakers providing overcurrent protection in household and similar installations.
Niglon lists Semko certification, CE marking and UKCA marking for this range of miniature circuit breakers.
The MCB is intended for installation by suitably qualified persons within compatible electrical distribution equipment.
