Product Overview
Description
Accurate, Reliable Performance
- Current Measurement-based Protection
While electromechanical overload relays pass motor current through heating elements to provide an indirect simulation of motor heating, the E1 Plus Overload Relay directly measures motor current. Current measurement based overload protection more accurately models a motor’s thermal condition. Furthermore, ambient temperature does not impact the performance of current measurement-based designs over the specified temperature operating range.
- Electronic Design
Thermal modeling is performed electronically with precision solid-state components; at the heart of the E1 Plus Overload Relay is an application specific integrated circuit (ASIC). The ASIC continually processes motor current data to accurately maintain the time-current status of the motor thermal capacity utilization value.
- Thermal Memory
A thermal memory circuit allows the E1 Plus Overload Relay to model the heating and cooling effects of motor on and off periods. This ensures accurate protection for both hot and cold motors.
- Enhanced Phase Loss Protection
A separate phase loss detection circuit incorporated into the E1 Plus Overload Relay allows it to respond quickly to phase loss conditions; typical reaction time is 3 seconds.
Easy to Select and Apply
- Straightforward Installation
The self-powered design means that the E1 Plus Overload Relay installs like traditional overload relays. Device setup is accomplished by simply dialing the setting potentiometer to the motor FLA rating. The low energy consumption of the electronic design minimizes temperature rise issues inside control cabinets.
- Wide Adjustment Range
A wide 5:1 adjustment range results in the need for half as many catalog numbers as the bimetallic alternative in order to cover the same current range. This helps to reduce inventory carrying costs and affords greater installation flexibility for dual voltage machines. Evenly spaced setting tick marks enhance the ease of installation setup.
Rugged Construction
- Insert Molded Power Connections
The unique line-side insert molded power connections make for a sturdy two-component starter assembly that is unmatched in the industry. The preformed power connections allow for easy starter assembly – every time.
- Current Transformers
The current transformers are secured separately in the overload housing to ensure the greatest degree of resistance to shock and vibration conditions. Varnished laminations ensure consistent performance and provide additional protection against corrosion.
- Latching Relay
The robust design of the bi-polar latching relay provides reliable trip and reset performance for the most demanding of applications. The self-enclosed relay offers additional environmental protection for use in industrial applications.
Application Flexibility
- Isolated Contacts
The isolated contact configuration allows the N.C. and N.O. contacts to be applied in circuits operating at different voltage levels and without polarity restrictions. The B600 contact rating affords application in circuits rated to 600V.
- DIP Switch Settings
DIP switch settings allow the selection of trip class (10, 15, 20, or 30) and the reset mode (manual or automatic), making these devices very versatile.
