Basler Electric ES Series Protection Relays

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

protection related to Generator, Transformer, Distribution, Process Control,

Auto Transfer Schemes, and Motor applications. ES relays offer many high-end

features not typically found in a low-cost device to provide simple, yet sophisticated,

protection for your applications. Multiple DIN-rail mounting options are available.

Product Features & Benefits

• Simplify protection by covering a wide range of applications using ES relays.

• Sophisticated fundamental sensing technology gives you high-end harmonic

protection capabilities that prevent false tripping and allows you to be more selective.

• DIN-rail mounting provides low-cost, fast, easy, and compact installation.

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

• Red and green LEDs on the front panel provide intuitive, easy-to-understand

indication of system status.

• Digital microprocessor design is extremely accurate to ensure a high level of

dependability and security, giving you confidence in your settings.

• The ES relay self-monitors to detect internal component failure and, in the unlikely

event of an internal failure, flashes the Power LED.

• Voltage and Frequency models are available in six standard input voltages and

extensive custom nominal voltages.

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

sources.

• Conformal coating improves protection against dust and corrosion.

• Accurate, repeatable, and reliable operation.
