The highly sophisticated CM-S/N range in ABBs new S-line housing offers two different types of connection terminals and is ideally suited for universal use. Double-chamber cage connection terminals make it possible to connect fires up to 2 x 2.5 mm2 (2 x 14 AWG), rigid or fine-strand, with or without ferrules. Potential distribution does not require additional terminals. Easy connect technology Innovative push-in connection terminals for tool-free installation. The connection is gas-proof and has the same direction as the double-chamber cage connection terminals.
