 Detailed Description

ESCO AUTOMATIC RV TRANSFER SWITCHES

These Recreational Vehicle (RV) switches are designed for fast and easy installation in RV applications only. Not for installation in homes, cabins or other residential applications.

ESCO transfer switches feature a rugged power-coated steel cabinet with re-settable branch-circuit rated circuit breakers as required. Switches are non-defeatable (break-before-make) double-throw switches.

ESCO AUTOMATIC RV TRANSFER SWITCH IDENTIFICATION & FEATURES

ES350 Designed for use with three connections and allows automatic switching between inverter, generator and shore power. Designed for generators having a rated output of 50 amps (or more) 120/240V AC single phase 60 hertz, external power source (shore power cord) of 50 amps 120/240 VAC single phase 60 hertz and up to 50A 120V AC inverter. 30 second time delay to allow generator to get up to speed. Mechanical and electrical interlocks to insure no power feedback. Monitors voltages on the generator side and/or shore power, when below 105 VAC for 10 seconds it will not allow power to pass through. Specify when ordering if you want monitoring only on the generator or shore otherwise monitoring will be provided on generator and shore sides. Designed to shed inverter loads when used with a 30 Amp transfer switch.

ES50M-65N Designed for usage as an electrical transfer switch to automatically switch multiple power sources (from one to another), i.e. switching from shore power to generator power. 30 second time delay to allow generator to get up to speed. Monitors for low voltage on the generator side. Cut off for low voltage is 90 VAC for 1 second.
The ES50M-65N is primarily designed for installation in conjunction with a generator having a rated output of not larger than 12 kW and an external power cord having a rated output of 240 VAC @ 50A, 1PH, 60HZ, Features: Automatically switches from power cord to generator. Heavy duty contactor assembly specifically designed for rigorous use, will handle 50 AMP power cord.
Transfers both hot and neutral legs simultaneously. Economical and reliable time delay switches automatically from shoreline to generator power.
Capable of monitoring for low generator voltage. Built-in time delay allows generator to get up to speed. Quick and easy installation. Designed for OEM and aftermarket applications. Please see factory brochure.
This is the most popular switch for RV's that we sell.

LPT30 Designed to switch automatically switches from (two sources, shore power to generator) by starting the generator when a need for power exists and there is no shore power. 30 second time delay to allow generator to get up to speed. Generator startup delay can be bypassed. Used for inverter applications with inverter load sensing circuitry. Allows inverter to operate in stand-by mode without unnecessary battery drain. Can switch 120VAC up to 30 amps It is designed for straight forward wiring. The metallic enclosure is provided with knockouts of various sizes. Just select the proper size, remove knockouts, and install cable clamps in knockout holes. The LPT30 is designed for use in a circuit capable of delivering not more than 500A rms symmetrical, 150V maximum, when protected by a circuit breaker not rated more than 30 amps. Please see factory brochure.
