Basler Electric ES Series Protection Relays

Overview

ES Series Protection Relays provide a wide range of cost-saving options to

simplify protection related to Auto Transfer, Distribution, Generators, Motors,

Process Control, and Transformers. Multiple DIN-rail mounting options are

available.

Features

• Fundamental sensing technology

• DIN rail mounting

• Covers a wide range of applications

• Models available in six standard voltages

• Many self-powered options

• Conformal coating for improved protection against dust and corrosion

• HMI

- Front Panel accessible adjustments

- Front panel Indications - Red indicates a fault condition,

green indicates a normal, non-fault condition.

• Digital microprocessor design

• Internal diagnostics

• High dependability and security

• Two form-C auxiliary contacts available on most models

• High quality relaying solutions based on more than 50 years of relaying

experience and more than 30 years of reliable digital relaying design.

Benefits

• Fundamental sensing technology provides high-end harmonic

protection capabilities that prevent false tripping and allow you to

be more selective with your settings.

• DIN-rail mounting provides easy, time-saving, and compact

installation.

• Simple, economical, yet sophisticated protection for generator,

transformer, distribution, process control, automatic transfer

schemes, and motor applications.

• Many ES relay models are self-powered, eliminating the need for

additional power sources.

• Relay settings are simple and intuitive, making setup fast with no

PC required.

• Red and Green LEDs ensure clear indication of system status to

avoid misinterpretations that could lead to downtime.

• Digital microprocessor design offers consistency for all models,

enhances functionality, and improves performance.

• Internal diagnostics self-monitor and visually annunciate when

relay function or accuracy is compromised, providing clear

understanding of the functional status of the device.

• High dependability and security means relays trip when they are

supposed to and do not trip when they are not supposed to.
