Description
A four-pole differential switch is designed for monitoring electrical circuits and protecting against leakage currents caused by insulation faults. It detects imbalances in current flow between phase and neutral conductors, immediately disrupting power to prevent shock hazards or equipment damage. Type A variants are suitable for detecting both AC and pulsating DC leakage currents.
### Electrical Specifications
Rated current: 40 amps maximum across four poles — suitable for systems with moderate load requirements. Sensitivity: 30 mA trip threshold ensures responsive fault detection, reducing risk of injury or fire caused by undetected leaks. Integrated delay feature allows brief tolerances to avoid nuisance tripping during transient conditions.
### Functional Characteristics
Type A classification focuses on compatibility with AC waveforms and rectified DC waveforms arising from modern electrical devices such as chargers, inverters, etc. Delayed tripping reduces unintended activation caused by momentary voltage fluctuations but is not intended for extended holdouts under actual fault conditions.
#### Technical Notes / Limitations
- Operates within a frequency range of 50-60 Hz only.
- Not rated for use in networks exceeding 400 VAC phase-neutral configuration.
- Complies with IEC/EN standards but only on correctly earthed installations.
- Delay function increases reaction time slightly; unsuitable where immediate disconnection is critical.
- Requires periodic inspection/testing per regional safety codes.
