TRIPPING CURVE COMPARISON

• 30 mA instantaneous RCD
• 30 mA APR (anti-disturbance) instantaneous RCD
• 300 mA selective RCD (type S)

* Type S RCDs have a delayed tripping action and are installed
upstream of other rapid RCDs to guarantee selectivity and limit
the power out only to the portion of the system affected by a
fault.
* APR devices which trip according to the limit times allowed by
the Standards for instantaneous RCDs.
