Not suitalbe for all other ECGs. Mounting By using an inrush current limiter, the installation effort in big systems will be reduced because a higher number of ECGs per strand and circuit breaker is possible. It is suitable for installation directly in the control cabinet (DIN rail dimensions) Installation example with PTi 70/220240 I (mains looping) e.g. up to approx. 32x PTi 70 I on one circuit breaker (16 A, B char.)
