Merlin Gerin's new NG125 range of miniature circuit breakers and residual
current devices provides robust industrial components in an
easy-to-install modular format. Breaking capacity is up to 50kA, which is
very high for modular, DIN rail mounting switchgear. The devices can be
used to protect circuits up to 125A, and are supplied in one- to
four-pole configurations with trip-free switch disconnectors, and 'vigi'
earth-leakage modules, with or without sensitivity and time delay
adjustment.
