Description

The Timeguard TX2316 16A B-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 a practical option for electricians selecting protective devices for a new consumer unit or replacing a compatible breaker during renovation work. The 16A rating and B-curve characteristic must match the circuit design, cable capacity and connected load.

What does B-curve mean?

The B-curve characteristic describes how the breaker responds to a high current over a short period. It has a lower instantaneous magnetic operating threshold than an equivalent C-curve MCB.

This is separate from its 16A rated current and 6kA short-circuit breaking capacity. Each figure serves a different purpose when selecting the correct protection for a circuit.

Terminals designed to help avoid incorrect connections

The terminal cages include blanking plates that help prevent a cable or busbar from being positioned outside the clamp. The maximum terminal capacity is 25mm², and the specified tightening torque is 2.5Nm.

A contact position indicator provides a visible indication of contact status. For maintenance, the breaker can be removed without removing the busbar once the installation has been safely isolated.

FAQ's

What is the Timeguard TX2316 used for?

It provides 16A overload and short-circuit protection for an individual circuit within a compatible Timeguard TX consumer unit. Its suitability depends on the circuit design.

Is the TX2316 B-curve or C-curve?

TX2316 is B-curve. The corresponding 16A C-curve model is TX2316C, so the final letter matters when ordering.

What does the 16A rating mean?

It is the breaker’s rated current under specified operating conditions. It does not mean that any appliance drawing up to 16A is automatically suitable for the circuit.

Will it trip immediately if the current exceeds 16A?

Not necessarily. Operating time depends on the size and duration of the overcurrent and the breaker’s time-current characteristic. An MCB does not behave like a precise 16A on/off threshold.

What is the instantaneous trip range of a B-curve MCB?

Under BS EN 60898-1, the B-curve instantaneous magnetic operating band is 3–5 times rated current. For a 16A device, that corresponds to 48–80A.

Does the 48–80A trip range allow it to carry that current continuously?

No. That band describes short-duration magnetic operation. The device’s rated current remains 16A.

How does TX2316 differ from TX2316C?

Both are 16A models, but their magnetic tripping characteristics differ. B-curve has a lower instantaneous operating threshold than C-curve. The correct version depends on the circuit’s load and fault-protection requirements.

Can I replace a 10A breaker with this 16A model?

Only after an electrician confirms that the circuit can be protected correctly at 16A. Cable size alone is insufficient: installation method, grouping, insulation, fault conditions and other design factors also matter.

Is it suitable for a 16A socket circuit?

A 16A socket rating does not establish suitability by itself. The electrician must confirm the circuit arrangement, cable protection, required residual-current protection and consumer unit compatibility.

Can it be used with LED lighting or equipment with a starting current?

Suitability depends on the equipment’s inrush characteristics and the circuit design. Check the equipment manufacturer’s protective-device guidance rather than selecting a breaker from running wattage alone.
