Basler Electric ES Series Protection Relays

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.

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.
