  Supplementary protectors are equipped with a delayed overload/time-dependent thermal release (thermal bimetal) for low overcurrent’s and with an instantaneous electromagnetic release for high overload and short-circuit currents. The thermal trip point on all versions is 1.13 to 1.45 times the supplementary protector rating.

  Tripping characteristic A, -5:
  To protect very sensitive circuits such as semiconductors. Magnetic trip point – 2 to 3 times supplementary protector rating.

  Tripping characteristic B, -6:
  For European residential circuit protection. Also for protection of computers and electronic equipment. Magnetic trip point
  – 3 to 5 times supplementary protector rating.

  Tripping characteristic C, -7:
  For general device protection in control circuits and all other supplementary circuit protection systems. Magnetic trip point
  – 5 to10 times supplementary protector rating.

  Tripping characteristic D, -8:
  For protection of high inrush loads. Magnetic trip point – 10 to 20 times supplementary protector rating.
