The Timeguard TX2350C 50A C-curve MCB protects an individual electrical circuit against overload and short circuit. Designed for Timeguard TX series consumer units, this single-pole miniature circuit breaker has a 6kA breaking capacity and occupies one module.
It is an option for electricians selecting a protective device for a compatible installation or replacing an existing breaker where the circuit requires 50A C-curve protection.
C-curve MCBs have a higher instantaneous magnetic operating threshold than equivalent B-curve breakers. This can accommodate brief starting currents where the connected equipment and circuit design support their use.
The current rating remains 50A. Choosing C-curve does not increase the circuit’s permitted continuous load. Cable protection, equipment starting characteristics and the fault current needed to achieve the required disconnection time must all be considered.

FAQ's
What is the Timeguard TX2350C?
It is a 50A C-curve single-pole miniature circuit breaker with a 6kA breaking capacity. It provides overload and short-circuit protection within compatible Timeguard TX consumer units.
Is TX2350C definitely C-curve?
Yes. The manufacturer’s datasheet lists this exact code in its C-curve range. The B-curve bullet on the product page conflicts with the heading and datasheet.
What is the difference between TX2350C and TX2350?
TX2350C is C-curve; TX2350 is B-curve. Both are rated at 50A, but their instantaneous magnetic operating characteristics differ.
What does C-curve mean?
Under BS EN 60898-1, the C-curve instantaneous magnetic operating band is 5–10 times rated current. Its magnetic operating threshold is higher than that of an equivalent B-curve device.
What is that operating band for a 50A C-curve MCB?
It corresponds to 250–500A. This describes short-duration magnetic operation, not a permitted continuous load.
Will it trip immediately when the current exceeds 50A?
Not necessarily. Operating time depends on the size and duration of the overcurrent and the breaker’s time-current characteristic.
Can I replace a 50A B-curve breaker with this model?
Only after an electrician verifies the circuit design. Changing the characteristic affects the fault current needed for rapid operation and may alter whether the required disconnection conditions are met.
