Description
The LM-ERO is a two-pole, cUL-listed, class-1008 (for
applications covered under NEC Article 702) automatic
transfer switch for use in optional standby systems. Each pole
has the ability to transfer a fully loaded 20-amp circuit, which
provides the ability to switch two independent, 20A hot leads
or the hot and neutral leads of a single circuit.
