RC Surge Snubber

RC Surge Snubber

2.4kV – 24kV RC Surge Snubber Transformer, Generator, Motor Protection

RC Surge Snubber | Transformer | Generator | Motor | Protection - APT
The APT Surge Snubber is designed to protect the insulation of medium voltage transformers, generators, and motors by reducing the rate of rise of the surge wave in the event of switching or lightning surges. Having an APT Surge Snubber installed will protect your equipment against the damage, chaos, and hazards that can be associated with switching and lightning surges.
