Description

The Timeguard TX2432C 32A 30mA Type A RCBO combines overload, short-circuit and residual-current protection in one compact device. Designed for Timeguard TX series consumer units, it has a C-curve overcurrent characteristic, a 6kA breaking capacity and a single-module housing.

Use it where the circuit design calls for 32A C-curve protection and the consumer unit is compatible. It is suitable for electricians selecting protective devices for a new installation or replacing an existing RCBO with the correct specification.

Understand Type A and C-curve

These classifications describe different functions. Type A residual-current protection responds to sinusoidal AC and pulsating DC residual currents. C-curve describes the overcurrent operating characteristic.

Compared with an equivalent B-curve device, C-curve has a higher instantaneous magnetic operating threshold. This can accommodate brief starting currents where the equipment and circuit design support its use. The rated circuit current remains 32A.

Solid neutral and unidirectional operation

This model has a solid neutral, which remains connected when the protected line pole opens. It should be distinguished from a switched-neutral RCBO when assessing the installation’s isolation requirements.

The device is also unidirectional. Supply and load connections must follow the manufacturer’s markings, and it must not be selected for a circuit requiring bidirectional power flow.

Practical terminals and maintenance features

Top terminals accept conductors up to 10mm², with a specified tightening torque of 1.2Nm. Bottom terminals accept up to 25mm², with a tightening torque of 2.5Nm.

Terminal blanking plates help prevent incorrect cable or busbar insertion. A test button and contact position indicator are included, and the RCBO can be removed without removing the busbar once the assembly has been safely isolated.

Measuring 18mm wide × 85mm high × 73mm deep, it mounts onto a 35mm DIN rail. Timeguard provides a five-year guarantee, subject to its applicable terms.

Manufacturer compatibility is limited to Timeguard TX series consumer units.

FAQ's

What does the Timeguard TX2432C protect against?

It combines overload, short-circuit and residual-current protection for an individual circuit. Its ratings are 32A, 30mA, Type A, C-curve and 6kA.

How does an RCBO differ from an MCB?

An MCB provides overload and short-circuit protection. An RCBO also incorporates residual-current protection to detect an imbalance between line and neutral currents.

What is the difference between 32A and 30mA?

32A is the rated circuit current. The 30mA figure is the rated residual operating current of the earth-leakage protection. They describe separate functions.

Why is it described as Type A and C-curve?

Type A describes the residual-current detection characteristic. C-curve describes the overcurrent operating characteristic. This is a Type A RCBO with a C-curve overcurrent function.

What residual currents can Type A protection detect?

Type A responds to sinusoidal AC and pulsating DC residual currents. It should not be treated as equivalent to Type B residual-current protection.

How does TX2432C differ from TX2432?

TX2432C is C-curve; TX2432 is B-curve. Both are listed as 32A, 30mA, Type A, solid-neutral unidirectional RCBOs.

Why might an electrician specify C-curve?

Its higher instantaneous magnetic operating threshold can accommodate brief starting currents where the equipment and circuit design support C-curve protection.

Can it replace a B-curve RCBO to prevent tripping?

Only after the cause of the tripping and the circuit design have been checked. Changing the characteristic can affect fault-disconnection requirements and will not correct overloads or wiring defects.

Does C-curve increase the permitted continuous load?

No. The rated circuit current remains 32A. The C-curve characteristic relates to the overcurrent response.
