Overload Relays

Solid State ESP200, Class 48, 958 and 958L General

NEMA CONTROL

PRODUCTS                                           

Designed for a wide variety of applications.The field selectable Trip Class 5,10, 20 or 30 can easily be set by 2 DIPswitches.

This eliminates the guess factor of an application requirements and provides reduced inventory for multiple applications.

The inherent benefits of the ESP200 ultimately results in cost savings for the user.

ESP200 has a 4:1 current adjustment range with a fine adjustment dial labeled in full load amps.

The heaterless overload minimizes the heat trapped in the enclosures, reduces cost for ventilation or cooling.

Easily accessible Reset button, provides visible and audible indications to ensure the tripped overload is ready to re-start.

Designed to replace thermal, or ESP100 overload relays for any application. It has the same dimensions and footprint

of the ESP100 overload relays.

It can be directly coupled to the contactors or remotely mounted. It can be used with other types of controllers for

applications requiring DP or IEC contactors. As a retrofit for other brands, it is used with a plate available

for retrofitting competitive products.

This overload is specifically designed for special applications, to provide excellent protection of hermetically sealed and

artificially cooled motors that require ambient insensitive and quick trip response times. Combined with a series

lockout relay, it provides unsurpassed protection for hermetically sealed compressor motors in air conditioning

applications. The combination of high trip speed, current adjustment, and ease of installation makes it suitable for these

applications. The trip curves are customized to provide proper overload protection for these loads without

causing nuisance tripping. It has selectable manual or automatic reset mode, and provides ground fault

selection to protect equipment from damage in case of a fault.

Specifically designed for the oil market and the cycling loads experienced with these types of pumping applications.

These overload relays provide protection for standard motors, oil well pump motors, multi-torque connections, and

ultra-high slip motors. Rotors can be damaged in less than 15 seconds during motor stall conditions

if electrical power is not removed. To prevent damage during motor stall, the 958L solid state overload removes the

power in 7 seconds at 250% lock rotor current. Therefore, the motor casing and the rotor will be protected from

being damage saving the user money and time.
