Crabtree Starbreaker Miniature Circuit Breaker - Type B - 16 Amp

Type B breakers trip at 3-5 times their rated current, suitable for low inrush loads. Type C breakers trip at 5-10 times their rated current, ideal for inductive loads like motors. Type D breakers trip at 10-20 times their rated current, used for very high inrush loads like transformers or welding equipment.

It signifies the maximum fault current the circuit breaker can safely interrupt without being destroyed. A 6kA capacity is suitable for most residential and light commercial installations where the maximum expected fault current is below this level.

This MCB is designed for modern distribution boards with specific busbar systems. It cannot directly replace old-style rewireable fuses or cartridge fuses without a compatible modern consumer unit.

For general kitchen sockets, a 16A Type B breaker may be suitable, but care should be taken if high-power appliances with significant inrush currents (like toasters or kettles) are on the same circuit. A Type C breaker is often preferred for kitchen sockets to prevent nuisance tripping.

Your distribution board must have a plug-in busbar system designed to accept Crabtree Starbreaker MCBs. Look for compatible Crabtree consumer units or check the manufacturer's specifications for your existing board.

Warranty details are typically provided by the retailer or manufacturer at the point of sale. Please refer to your purchase documentation for specific warranty information.

Miniature circuit breakers like this one are generally designed and rated for AC (Alternating Current) circuits only. Using them on DC circuits can be unsafe and lead to improper operation or failure.

Check if the load exceeds the 16A rating. Verify if the circuit has high inrush current devices; consider a Type C breaker if necessary. Inspect wiring for potential faults.

Ensure the fault condition has been cleared. If the breaker remains unresettable, it may be damaged and require replacement by a qualified electrician.

Slight warmth can be normal under load, but excessive heat indicates a potential issue. Check connections for tightness and inspect for signs of arcing or damage. Consult an electrician.
