Overview
The VKL11F is a Type F residual current circuit breaker for AC 50/60 Hz installations incorporating single-phase frequency converters and electronically controlled equipment. It detects sinusoidal AC, pulsating DC and composite or mixed-frequency residual currents up to 1 kHz. The range includes 16 A to 100 A ratings, 30, 100 and 300 mA sensitivities, and 2P or 4P configurations. Voltage-independent magnetic operation, short-time delay and surge-current immunity support use in residential, commercial and industrial installations. The RCCB must be used together with suitable overload and short-circuit protection.
Features
- Detects sinusoidal AC, pulsating DC and mixed-frequency residual currents up to 1 kHz.
- Maintains normal functionality with superimposed smooth DC residual current up to 10 mA.
- Voltage-independent magnetic operation with short-time delay.
- Surge-current immunity up to 3 kA.
- Mechanical red/green contact-position indicator.
- Designed according to IEC/EN 62423 and IEC/EN 61008-1.
