Automatic Transfer Switch
100 amp, 120/240V, 1-phase
with generator exerciser
(integral service entrance disconnect optional)

The Eaton Cutler-Hammer RLC Residential/Light Commercial Automatic Transfer Switch complements remote start generator sets allowing the standby power system to be fully automatic.  This contactor-based switch is perfect for applications where adjustable voltage and time delay settings are not required.  Settings are fixed at values that are suitable for most applications.  100 and 200 amp ratings are available with indoor and outdoor enclosures.

The RLC Automatic Transfer Switch combines reliability and flexibility in a small, economical package for transferring loads between the utility and generator sets.   This transfer switch works together with any remote-start generator using two-wire start control.  The controller in the switch monitors utility and emergency standby power generator power.  When utility power fails or is unsatisfactory, the controller starts the generator set and transfers the load to the generator set.  When the controller senses that utility power is restored it automatically transfers back to utility power, shutting down the generator and instantly resetting itself for the next power interruption.  No action is required by site staff.

Enclosures
The transfer panel and control are mounted in a single hinged door NEMA 1 (indoor) or 3R (outdoor) enclosure.

Optional Service Entrance Rated
This switch can be service entrance rated as an option.  If there is no service entrance rated disconnect between this switch and your utility meter, select this option to save purchasing, installing and wiring a separately mounted disconnect.

Positive Interlocking
Mechanical contactor interlocking prevents simultaneous closing of normal and emergency contacts.  Independent break-before-make action positively prevents dangerous source-to-source connections.

Microprocessor Control
Reliable, microprocessor based control system with undervoltage monitoring of the utility and voltage and frequency sensing of the generator, standard time delays.   This switch now comes standard with the Eaton ATC-100 controller which provides timing functions, voltage & frequency sensing and the generator exerciser.  The new RLC1 series switch with the ATC-100 controller replaces the old RLCM series.

Agency Approvals
Complies with NEMA ICS 10
Conforms to applicable requirements for NFPA 110
UBC and BOCA Uniform building code for Seismic Zone 4
Listed to UL 1008, CSA, IEC listed to 240 VAC 50/60 Hz
ISO 9001 and 14001

 

Specs

NOTES:
1) The start time delay prevents nuisance generator starts during momentary utility power variations; transfer time delay allows generator set to stabilize before load is applied; retransfer delay prevents needless power interruption if return of utility power is momentary; stop delay allows gradual generator set cool down; undervoltage sensing of utility supply provides reliable starting of generator set during brownout conditions.
2) This switch can be service entrance rated as an option.  If there is no service entrance rated disconnect between this switch and your utility meter, select this option to save installing a separately mounted disconnect.
3) The RLC contactor comes with 2 power poles to switch the two hot leads of a 120/240V system.  It does NOT switch the neutral, which is acceptable in most areas of the USA.  See article 250.20 of the 2002 NEC.  If there are special requirements in your area that require switching the neutral (as dictated by local codes or electrical inspectors) you must use a different transfer switch.
4) This switch provides a single isolated contact for controlling the genset.  The contact closes when the genset is to start and run.
