A9V31363

What does this earth-leakage add-on block do?

This Acti9 Vigi iC60 module adds residual-current protection to a compatible miniature circuit breaker. It detects earth-leakage current and operates the associated breaker when the specified threshold is reached.

What are its rated current and earth-leakage sensitivity?

The A9V31363 has a rated current of 63 A and an earth-leakage sensitivity of 30 mA. These describe its current rating and residual-current operating threshold respectively.

How many poles does the module have?

The module has three poles, making it suitable for compatible three-pole circuit-breaker assemblies. Its rated operational voltage and connection arrangement should be checked against the intended circuit.

What type of residual-current protection does it provide?

It provides Type A-SI protection, with SI denoting Super Immunised. This classification should be considered when selecting residual-current protection for the electrical characteristics of the connected loads.

Does the residual-current protection have an intentional time delay?

No. The module is specified as instantaneous rather than time-delayed. This describes its residual-current operating characteristic, not a zero-duration trip time.

Which circuit-breaker ranges are compatible?

The datasheet lists compatibility with Acti9 iC60 and Acti9 Reflex iC60 devices, with single-terminal product compatibility specified. The exact breaker configuration should be checked before combining the devices.

Can the module be used as a standalone circuit breaker?

No. It is an add-on residual-current device intended to operate with a compatible circuit breaker, rather than a standalone breaker. Overcurrent protection is provided by the associated circuit breaker.

What supply voltage and frequency is it designed for?

The A9V31363 is designed for AC networks operating at 50 or 60 Hz. Its rated operational voltage is 400 V AC under EN 61009-1 and 400/415 V AC under IEC 61009-1.

How is the module mounted and connected?

The module uses clip-on mounting on a DIN rail and connects to the associated miniature circuit breaker using screws. Bottom connection compatibility is listed for comb busbars and distribution blocks.

What are the dimensions and weight?

The module measures 91 mm high, 117 mm wide and 73.5 mm deep, with a net weight of 0.21 kg. Space planning should also account for the associated breaker and wiring.

Which conductor sizes do the terminals accept?

The bottom tunnel terminals accept one rigid conductor from 1 to 35 mm², or one flexible conductor from 1 to 25 mm². Flexible conductors can be used with or without cable ends, within the stated range.

What are the specified wire stripping length and terminal tightening torque?

For the bottom connections, the specified wire stripping length is 14 mm and the tightening torque is 3.5 N·m.

What degree of ingress protection does it offer?

The device is rated IP20, with IP40 specified when installed in a modular enclosure. Both ratings are stated in accordance with IEC 60529.

What operating and storage temperatures are specified?

The specified ambient operating temperature is −25 to +60 °C. The storage temperature range is −40 to +85 °C.

Does the module provide a local trip indication?

Yes. A local trip indicator is included to show that the device has tripped.

Is the residual-current tripping technology voltage independent?

Yes. The datasheet specifies voltage-independent residual-current tripping technology. The device must still be selected and installed within its stated electrical ratings.
